ЦитироватьChennai: The 640-tonne GSLV Mk-III, Isro's heaviest rocket till date, is likely to be launched in January as some stages of the rocket are still undergoing tests.

Isro first had planned to launch the heavy rocket in December end. But the largest cryogenic engine CE-20 developed for this rocket is yet to be delivered as it is undergoing tests at Isro's Propulsion Complex (IPRC) in Mahendragiri, Tamil Nadu.

The indigenous first developmental vehicle is capable of placing the 4-tonne class GSAT satellites into the Geostationary Transfer Orbit. The 43.43-metre tall vehicle has the liquid and cryogenic stage and two S200 solid rocket boosters.

"All the systems are now getting ready. The L110 and S200 stages are already delivered to Satish Dhawan Space Centre in Sriharikota. The cryogenic engine CE-20 is still not delivered as the engine tests are going on," K.Sivan, director, Vikram Sarabhai Space Centre (VSSC), Thiruvanan thapuram told Deccan Chronicle.

The cryogenic stage for the vehicle is expected to be delivered sometime in December. "The exact date for the launch will be finalised only when we finish our tests. It's not like PSLV or GSLV launches. It's a new stage, new testing and some new observations will be there and we have to solve the teething issues. In all likelihood, the launch may go to January," he said.

GSLV-Mk-III rocket will launch the 3.2-tonne GSAT-19 satellite into the Geosynchronous Transfer Orbit. "GSLV-Mk-III will launch the satellite like our regular GSLV rocket," K.Sivan said.

The 25-metre height solid rocket boosters will burn 207 tonne of solid propellant each to give the required thrust to lift off the vehicle. The GSAT-19 satellite will carry Ka and Ku-band payload along with a Geostationary Radiation Spectrometer (GRASP) payload to monitor and study the nature of the charged particles and influence of space radiation on spacecraft and electronic components.

Earlier, Isro had tested the 3,775 kg Crew Module Atmospheric Re-entry Experiment (CARE) using the GSLV-Mk-III rocket which flew with a passive cryogenic stage. The module re-entered the atmosphere from the height of 126 km and deployed its parachutes as planned and splashed down in the Bay of Bengal.

Департамент также сообщил о готовящемся в первом квартале пуске ракеты-носителя GSLV–D1 с криогенной ступенью. Ракета выведет на орбиту коммуникационный спутник GSAT-19. В сентябре Индия впервые применила криогенную ступень в рабочем порядке во время запуска метеорологического спутника INSAT-3DR. В более ранних пусках ее включали в тестовом режиме.

В департаменте космических исследований рассчитывают, что грузоподъемность GSLV–D1 будет доведена до 4 тонн полезной нагрузки. Также индийские ученые рассчитывают получить одобрение на развитие полукриогенной ступени. Они уже разрабатывают такой двигатель и ожидают, что полукриогенная ступень будет готова в течение пяти лет.

ЦитироватьThe Indian Space Research Organisation (ISRO) successfully conducted the test of the Geosynchronous Satellite Launch Vehicle Mk III's indigenous cryogenic CE-20 engine at ISRO Propulsion Complex in Mahendragiri in the district on Saturday.

The CE-20 was ignited and tested for 25 seconds from 7.20 p.m. in the presence of A.S. Kiran Kumar, Chairman, ISRO, to study the performance of the engine that will play a pivotal role in the rocket weighing about 4 tonne.

"The engine, which will get ignited at high altitude in vacuum during actual flight, performed exceptionally well to meet all predetermined goals," said sources in the ISRO Propulsion Complex.

ЦитироватьSivan said GSLV MK III is scheduled for launch on January 20, 2017.

ЦитироватьGSLV MKIII, the future launch vehicle of ISRO, capable of launching 4-ton class spacecraft into Geosynchronous Transfer Orbit (GTO) is in the advanced stage of realisation. It consists of two solid strap-on (S200) motors, one earth storable liquid core stage (L110) and the indigenously developed C25 cryogenic stage. The C25 stage is powered by CE20 cryogenic engine. The first CE20 flight engine acceptance test was successfully conducted for a duration of 25 seconds in high altitude simulation test facility during December 2016. This flight acceptance test is an important milestone for ISRO as it could successfully cross the major engine development endeavors in the maiden attempt. This engine was conceived, configured, designed, fabricated and developed by Liquid Propulsion Systems Centre (LPSC).

LPSC is the centre for design, development and realisation of liquid propulsion stages for ISRO's Launch Vehicles. Development of fluid control valves, transducers, propellant management devices for vacuum conditions and other key components of liquid propulsion systems are also under the purview of LPSC.

To test the Engine at flight identical conditions, High Altitude Test (HAT) facility was established at IPRC, Mahendragiri. This facility allows testing of the CE20 engine at its full area ratio in vacuum condition which otherwise would experience flow separation at sea level ambient pressures.

The successful engine testing in the high altitude conditions was preceded by multiple tests on two engines with sea level nozzle divergent (area ratio 10). The development test conducted on these engines provided confidence in their design. The design of the flight nozzle was also validated in the medium duration High Altitude Test programme.

The Engine High Altitude Test Programme contained a series of high altitude tests (5 hot tests with a cumulative duration of 41.20 sec) to demonstrate the vacuum ignition, validate the nozzle performance, propellant flow build up characteristics, chill down performance and to demonstrate the ignition margins. All the test objectives were successfully achieved in this test programme. The testing of engine in HAT facility has also helped in finalising the engine start and shut down sequence for flight. Summing up, the test programme has imparted good confidence on the performance and functioning of CE20 Engine in GSLV MKIII (LVM3)-D1 mission.

The realisation of flight stage for the GSLV MKIII (LVM3)-D1 mission is in progress and the first mission is expected by early 2017.

ЦитироватьChennai: Isro has postponed its heaviest rocket GSLV Mk-III's launch due to pending tests to be conducted on the vehicle. Now, the rocket will either be launched in March or April after completing the tests.

Earlier, the space organisation tentatively planned to launch it on January 20. The GSLV Mk-III rocket will launch the 3.2 tonne GSAT-19 satellite.

"Subsequently, some more tests are planned for the vehicle and the stage level tests also got delayed. Now, these tests will be conducted this month. If any issues arise during the tests we will correct them," K. Sivan, director, Vikram Sarabhai Space Centre (VSSC), Thiruvananthapuram told Deccan Chronicle.

The high altitude test for GSLV Mk-III's large cryogenic engine CE-20 was conducted in December. Isro also plans to send the Saarc satellite with GSLV Mk-II rocket in March.

"We are planning to launch both the GSLV Mk-III and GSLV Mk-II rockets in March and April. Maybe one will be launched in March and another one in April depending on the availability of the launch pad," he said.

ЦитироватьThe Indian Space Research Organisation (ISRO) successfully tested its indigenously developed Cryogenic Upper Stage (CUS) for GSLV MkIII on February 17, 2017. The cryogenic stage designated as C25 was tested for a flight duration of 640 seconds at ISRO Propulsion Complex (IPRC) in Mahendragiri. C25 Stage had earlier been tested successfully for 50 seconds on January 25, 2017 to validate all the systems.

Prior to Stage development hot tests, three CE20 engines were realised and two engines were subjected to qualification tests in sea level conditions. This included 800 seconds duration hot test and the third engine identified for flight was tested in high

Altitude conditions for a duration of 25 seconds.

This Stage test is a significant milestone as it is the last in series of engine and stage development hot tests before the first development flight of GSLV MkIII.

The C25 stage is the most powerful upper stage developed by ISRO and uses Liquid Oxygen (LOX) and Liquid Hydrogen (LH2) propellant combination.  The stage carries 27.8 tons of propellants loaded in two independent tanks. Development of a cryogenic stage has unique design challenges, with liquid Hydrogen stored at -253 deg C and liquid Oxygen stored at -195 deg C in its tanks. To store these cryogenic fluids, special multi-layer insulation is provided for the tanks and other structures.

The development of the cryogenic stage was led by Liquid Propulsion Systems Centre (LPSC) with support from various System Development Agencies from other ISRO Centres of ISRO, viz., Vikram Sarabhai Space Centre (VSSC), ISRO Propulsion Complex (IPRC) and Sathish Dhawan Space Centre (SDSC), SHAR.

The Cryogenic Stage development tests were carried out in two phases.  First, the Stage was subjected to fluid mock-up, wherein the stage preparation and servicing at launch complex in SDSC, SHAR, Shriharikota was completed to prove all the ground facilities established for servicing the cryogenic stage. This was followed by testing of the Stage at ISRO Propulsion Complex, Mahendragiri. From the Stage realisation to completion of testing was accomplished in four months.

The performance of the Stage during the hot test was as predicted. Successful hot test for flight duration qualifies the design of the stage and the robustness of the facilities conceived and established towards its development.

The flight cryogenic stage is in advanced stage of realisation, and forms the upper stage of GSLV MkIII the next generation launch vehicle of ISRO, capable of launching 4 ton class satellites into Geosynchronous Transfer Orbit (GTO). The vehicle consists of two solid strap-ons (S200) motors, one earth storable liquid core stage (L110) and the Cryogenic Upper Stage (C25).

ЦитироватьИндия успешно испытала собственный криогенный двигатель для тяжелой ракеты-носителя
НЬЮ-ДЕЛИ, 18 февраля. /Корр. ТАСС Евгений Пахомов/. Индийская организация космических исследований провела успешное испытание криогенного двигателя собственной разработки, предназначенного для тяжелой ракеты-носителя нового поколения. Как сообщает телеканал NDTV (http://www.ndtv.com/india-news/isro-tests-indias-largest-cryogenic-engine-for-400-ton-rocket-1660935?pfrom=home-lateststories), силовой агрегат проработал полные 10 минут.
Испытания состоялись днем ранее на территории двигателестроительного комплекса в Махендрагири на юге страны. Силовой агрегат предназначен для установки на новой индийской ракете-носителе GSLV Mark III  высотой около 50 м и весом более 414 тонн. Эти испытания стали последними перед запуском ракеты, который может состоятся в этом году, указывает телеканал.
Новый мощный носитель GSLV Mark III сможет выводить грузы до 10 тонн на низкую околоземную орбиту и до 4 тонн - на геосинхронную орбиту. Планируется также, что он может быть использован для выведения на орбиту первого индийского космического корабля с людьми на борту. В перспективе GSLV Mark III также предназначается для запуска межпланетных автоматических станций.
Как указывает NDTV, разработка нового двигателя потребовала почти 20 лет, поскольку в 1990-е годы Россия под давлением США была вынуждена отказаться от передачи индийской стороне технологий производства криогенных силовых установок. Создание такого двигателя - очень сложная задача, ее смогли решить только РФ, США, Франция, Китай, Япония и Индия, отмечает телеканал.

ЦитироватьGSLV Mark III launch: Why ISRO's biggest challenge will be at the end of this month

By HARI PULAKKAT, ET Bureau | Upd ated: May 02, 2017, 11.36 AM IST

Every engineer works under constraints. For those designing the third generation geostationary launch vehicle (GSLV), the main constraints were the launch facilities at Sriharikota and the capabilities of Indian industry. They could design a big rocket, but the Indian Space Research Organisation (Isro) would have had to build an expensive place to launch them. They would have also had to find companies to make the vehicle components, as making big rocket components was beyond industry capabilities.

Спойлер

When Isro started developing this rocket a decade and a half ago, it was far fr om being a thoroughbred organisation. It was not of great repute, its technical skills not cutting edge and its commercial potential, negligible. The first generation GSLV had just been test-flown, but its satellite had not reached its desired orbit. The GSLV Mark III was a complex vehicle and some of its critical technologies had to be developed from scratch. Isro's cryogenic engine development had hit hurdles and got delayed beyond reasonable measure.

However, by the turn of the century, Isro had shown glimpses of its current prowess. It had learned the art of making satellites. Its polar satellite launch vehicle (PSLV) had begun to put remote-sensing satellites into low earth orbit with precision, and this vehicle was slowly acquiring a reputation for reliability. The PSLV was relatively easier game.

The GSLV was a different matter altogether, requiring powerful solid motors and liquid engines in the early stages and a cryogenic engine on top. GSLV Mark III was conceived as a heavy lifter, by Indian standards, capable of putting communication satellites into a geostationary orbit, 36,000 km above the earth. A powerful cryogenic engine needed to be developed quickly.

Isro is now readying the vehicle for its first full flight at the end of this month, roughly three weeks after another flight of the current generation GSLV on May 5. Isro has used new ideas in its design, necessitating new methods in manufacturing. Some of these ideas will be tested for the first time in a flight from Sriharikota. It would be the first flight of GSLV III using India's fully-indigenous cryogenic engine. If successful, it would also be India's first launch vehicle qualified for human space flight. "This vehicle is going to be at the frontier for Isro," says G Ayyappan, Mark III project director. "It can be used for human flight as well."

Спойлер

All of these combine to make it one of the most critical flights in Isro's history. Although the space technology frontier has moved on, promising to keep Isro engineers busy for a long time, GSLV Mark III is the culmination of all that Isro initially set out to do when first se t up in the 1960s. When fully ready, it would give Isro self-reliance and the ability to put any satellite into any orbit.

The current flight of GSLV III is a developmental flight. Isro is planning another developmental flight a year later. It takes at least two flawless developmental fights for the vehicle to be ready for commercial use. This year, India will put two communication satellites in orbit using the French Arianne launcher. One of these satellites will weigh 5.6 tonnes. It is beyond the capabilities of even the current GSLV III, which is now being developed to put four-tonne satellites into geostationary orbit. Later versions of the GSLV will be able to put satellites weighing up to seven to eight tonnes into geostationary orbit.

Isro had gone through a difficult period a few years ago, when a launch of its GSLV Mark II failed. This failure had its impact on GSLV Mark III as well. "Because we had problems with Mark II," says Isro chairman Kiran Kumar, "we had to rework some facilities of Mark III for Mark II. So Mark III got slightly delayed." The successful flight of GSLV Mark II in 2014 was thus a major milestone for Isro. It also qualified India's cryogenic engine, which was a reengineered version of the Russian cryogenic engines.

The cryogenic engine in Mark III is entirely designed in India, and is twice as powerful as the Mark II cryogenic engines. Isro has used a different technology for this engine called the gas-generator cycle, primarily because it gave the engineers the freedom to test each component separately. The earlier engine used a method called staged combustion, wh ere the entire engine had to be tested as one entity. "We have now made about 200 tests on the engine and its components separately," says Kiran Kumar.

For the cryogenic engine, Isro had to create new high altitude test facilities at Mahendragiri near Thiruvananthapuram. Isro tested the full engine in April 2015 for 635 seconds, and again in June 2015 for 800 seconds, well beyond the duration of its burning during a real flight. It had two more tests subsequently, one early in 2016 and another in December 2016. The performance of the new cryogenic engine would be the most crucial aspect of the flight later this month, as it is being tested for the first time in a flight. Although there are other new features in the vehicle, some of these have already been tested in a partial flight two years ago. "We had doubts about the configuration," says K Radhakrishnan, former chairman of Isro. "So we decided to have an atmospheric test flight with a passive cryogenic engine."

This flight was on December 18, 2014, when Isro tested the recovery of a crew module. Isro had doubts about the configuration because it had two boosters on either side of the liquid core stage, with the core stage not firing with the boosters. GSLV Mark II had four strap-on motors surrounding the core stage. "The aerodynamics of Mark III special because the strap-ons are in one plane," says S Somanath, former project director of GSLV Mark III and now the director of the Liquid Propulsion Systems Centre near Thiruvananthapuram. The absence of strap-ons in the other plane makes the pitching and yawing manoeuvres slightly different.

At 3.2 meter in diameter, the strap-on motors are the third largest in the world. Apart from their size, the use of two strap-on motors provided another challenge for Isro. The two motors had to match their performance precisely. If not, one would tilt the vehicle to the other side during flight. To avoid this imbalance, Isro made the boosters from one casting, by splitting it into two. It was Isro's first attempt at pair casting. It was to ensure uniformity of material and uniform degradation and it needed the development of new infrastructure.

GSLV Mark III has a core liquid stage with twin engines, another – smaller – novelty in design. The liquid engines would switch on only a 100 seconds after lift-off, but well before the strap-on motors cease firing. The launch vehicle has redundant control electronics, a requirement for any vehicle used for human flight. Isro engineers have provided Mark III with other requirements for human flight vehicle, in terms of acceleration, noise and other safety margins. Isro has already designed and test-flown a crew module.

In the end, the decision for a human flight rests with the politicians. Whether the country embarks on a human flight or not, it is necessary for Isro to design vehicles that can carry heavier and heavier payloads. Not just for communication satellites, but for future inter-planetary missions as well. The GSLV Mark III will fly this month with a 3.2-tonne satellite, the GSAT-19. The vehicle is designed to take a payload of four tonnes, but it would still not be enough for some of Isro's future requirements.

"Satellites are getting heavier and heavier," says K Sivan, director of the Vikram Sarabhai Space Centre (VSSC) in Thiruvananthapuram. "So we have to increase the capacity of the vehicle." GSLV Mark III can be tweaked to later to carry more than six tonnes of payload into a geostationary orbit, by replacing the core liquid stage with a semi-cryogenic engine. This engine is under development, and might take three to four years. After its development, India would be able to put six to seven tonne-class of satellites into a geostationary orbit, and stop using expensive overseas facilities for launching its communication satellites.

TNN | May 11, 2017, 09.36 AM IST

(https://img.novosti-kosmonavtiki.ru/221357.jpg)

THIRUVANANTHAPURAM: After the successful launch of GSAT-9 on board GSLV-Mk II, scientists of ISRO centres here including Vikram Sarabhai Space Centre (VSSC) and Liquid Propulsion Systems Centre (LPSC) are back from Sriharikota. Now, the team of scientists and engineers are focussed on the next mission - GSLV-MK III, boosted with fully indigenous cryogenic engine. The GSLV-Mk III will launch the communication satellite GSAT-19 in May.

"In the previous GSLV launches, some parts of the indigenous cryogenic upper stage (CUS) engine were procured from Russia, but GSLV-Mark II had more indigenous CUS with propellant acquisition system. We used electric propulsion for the first time as part of the launch," said VSSC director K Sivan.

GSLV-Mark II was the eleventh flight of Geosynchronous Satellite Launch Vehicle (GSLV) and the fourth consecutive success achieved by GSLV carrying indigenously developed CUS, the scientists said.

"Now we are focussed on the launch of the developmental flight of GSLV-Mk III-D1 to launch the GSAT-19, a communication satellite with advanced spacecraft technologies including bus subsystem experiments in electrical propulsion System and indigenous lithium ion battery," GSLV Mk III project director G Ayyappan said. This GSLV-MK III rocket with totally indigenous CUS will weigh about 3.5 tons as against the GSLV-MK II vehicle with indigenous CUS stage weighing 2.2 tons, he said.

LPSC director S Somnath had earlier said that the GSLV-Mk III is set to launch the communication satellite GSAT-19 by May end and then Earth observation satellite Cartosat-2E will be launched via PSLV-C38 by June first week.

ЦитироватьHYDERABAD, MAY 12:  In yet another major step towards being self reliant in the country's space programme and tap into opportunities in the global marketplace, the Indian Space Research Organisation will launch GSLV Mark III-D1 with a payload of four tonnes on June 5.

"As on today, ISRO has the capability to launch payloads of up to 2.2 tonnes and anything above that it had to tap Ariane or other launch facilities. This will be a significant move from us," the ISRO Chairman and Secretary, Department of Space, AS Kumar, said.

The Geosynchronous Satellite Launch Vehicle Mark III is a gamechanger capable of launching 4-tonne category of satellites from Sriharikota. It packs an Indian cryogenic third stage and higher payload as against the current GSLV.

Apart from deploying advanced spacecraft technologies, the satellite would carry ka and ku-band payload along with a Geostationary Radiation Spectrometer that will help research space radiation.

Outreach

The Space Secretary said that ISRO will soon launch an innovative Outreach centre in Hyderabad, which would serve as a hub/centre for research, and base for start-ups and entrepreneurs to explore new business opportunities.

The huge amount of data collected by various space missions, and its learnings would be made accessible to people. This centre is expected to come up near Jeedimatla in the city limits.

In a boost to the country's quest to drive electric vehicles, ISRO has outlined plans to share its learnings and expertise in lithium ion battery technologies for commercial use.

Kiran Kumar said, "Over the years, ISRO has developed a number of technologies towards indigenisation and self reliance, and the capability of developing efficient lithium ion batteries is one such area which we can share for further development."

"We have developed technologies which help batteries run for up to 10-12 years and even more. This learning can be shared with entrepreneurs for commercialisation and come out with cost effective batteries for use in electric vehicles and other applications." he said.

Speaking at the Indian Institute of Chemical Technology, the ISRO chief said: "ISRO handled more than 151 missions that have been completed. These include 88 satellite programmes and 59 satellite launch vehicles."

"The launch of 104 satellites on a single mission earlier this year demonstrated our space technology capability," he said.

Referring to ISRO contributions, he said that the technologies developed and data available through various satellites it has launched is being used for applications in agriculture, weather forecasting and in tele-medicine. Efforts are on to see if a Postman could serve as a link between farmers and government, he said.

НЬЮ-ДЕЛИ, 5 июня. /Корр. ТАСС Евгения Кармалито/. Крупнейшая в Индии ракета-носитель собственной разработки GSLV Mark III (LVM3), способная вывести на орбиту полезный груз весом до 4 тонн, впервые успешно запущена в космос. Об этом сообщила Индийская организация космических исследований (ISRO).
"Запуск ракеты GSLV Mark III с криогенным двигателем, которая вывела на орбиту спутник связи GSAT-19 весом 3336 кг, состоялся на территории Космического центра имени Сатиша Дхавана на острове Шрихарикота в штате Андхра-Прадеш в 17:28 по местному времени (14:58 мск), - заявил глава ISRO Киран Кумар. - Это большой рывок для нашей космической отрасли: до сих пор полезная нагрузка ограничивалась 2,2 тонны. До конца текущего года мы проведем еще один испытательный запуск GSLV-Mk III-D1, еще более увеличив нагрузку".

По его словам, новая ракета позволит в перспективе полностью отказаться от услуг других государств при запуске крупных индийских спутников. "Новая индийская ракета-носитель со стартовой массой 640 тонн теперь регулярно будет выводить на орбиту аппараты весом в 4 тонны, - подчеркнул глава ISRO. - Более того, с таким носителем Индия может рассчитывать на большую долю на рынке международных космических запусков, который составляет $300 млрд в год".

Кроме того, GSLV-Mk III-D1 позволит Индии воплотить давнюю мечту о создании собственной орбитальной станции. "Теперь у нас есть все возможности для создания космической станции, надо лишь определить сроки и получить финансирование", - заявил Киран Кумар. По его словам, Индия до сих пор не приступила к пилотируемым полетам в космос только потому, что у страны не было ракет-носителей с достаточной грузоподъемностью, "но теперь этот вопрос практически решен, теперь при условии одобрения программы правительством на отправку человека в космос потребуется всего семь лет".

First Developmental Flight of India's GSLV MkIII Successfully launches GSAT-19 Satellite

The first developmental flight (GSLV MkIII-D1) of India's heavy lift launch vehicle GSLV Mk-III was successfully conducted today (June 05, 2017) evening from Satish Dhawan Space Centre SHAR, Sriharikota with the launch of GSAT-19 satellite. This was the first orbital mission of GSLV MkIII which was mainly intended to evaluate the vehicle performance including that of its fully indigenous cryogenic upper stage during the flight.  Weighing 3136 kg at lift-off, GSAT-19 is the heaviest satellite launched from the Indian soil.

After a twenty five and a half hour smooth countdown, the mission began with the launch of the 640 ton GSLV Mk-III at 5:28 pm IST from the Second Launch Pad as scheduled with the ignition of its two S200 solid strap-on boosters.Following this, the major phases of the flight occurred as scheduled.  The upper stage of GSLV MkIII vehicle is a new cryogenic stage (C25) indigenously configured, designed and realised by ISRO. The cryogenic stage used liquid Hydrogen and liquid Oxygen as propellants with a total loading of 28 tons. The stage is powered by a 20 ton thrust cryogenic engine (CE20) operating on 'gas generator cycle'. The performance of the engine and stage during the mission was as predicted.  About sixteen minutes after lift-off, GSAT-19 satellite was successfully placed in orbit.

Soon after its separation from GSLV, the Master Control Facility (MCF) at Hassan in Karnataka assumed control of the satellite.   GSAT-19 is a high throughput communication satellite.

In the coming days, GSAT-19 orbit will be raised from its present Geosynchronous Transfer Orbit (GTO) to the final circular Geostationary Orbit (GSO) by firing the satellite's Liquid Apogee Motor (LAM) in stages.  During the final phase of this operation, the solar panels and antenna reflectors of the satellite will be deployed. The satellite will be commissioned into service after its positioning in the designated slot in the GSO following in-orbit testing of its payloads.

India's GSAT-19 satellite reached a near-Geostationary Orbit on Saturday after a re-planned orbit-raising campaign that was necessitated by a slightly off-target delivery of the high-throughput communications satellite by the new GSLV Mk. III launch vehicle.

GSAT-19 became the heaviest satellite launched from Indian soil on Monday when taking flight atop the GSLV Mk. III, (http://spaceflight101.com/gslv-mk3-d1/gslv-mk-iii-first-orbital-launch-success/) making its first all-up orbital test flight to become the newest and most-powerful member in India's launcher fleet.

GSLV Mk. III blasted off from the Second Launch Pad at the Satish Dhawan Space Center at 11:58 UTC on Monday under the power of its two large Solid Rocket Boosters, outputting a maximum liftoff thrust of 1,050 metric-ton force. Monday's liftoff marked a major achievement for the Indian Space Research Organization after 16 years of work on the Geosynchronous Satellite Launch Vehicle Mark III that is ultimately envisioned to handle heavy Geotransfer missions supporting all of India's satellite programs that currently rely on foreign launchers.

Blazing away from India's East Coast toward the south East, GSLV Mk. III fired up its two-engine L110 core stage one minute and 55 seconds into the flight followed 26 seconds later by the separation of the spent boosters. The core stage and its twin Vikas 2 engines delivered 156 metric ton-force of thrust over a burn of three minutes and 23 seconds, in the process accelerating the stack to 4.0 kilometers per second (relative velocity).

This set up for the moment of truth, coming when the C25 Cryogenic Upper Stage fired up its 200-Kilonewton CE-20 engine, India's most-powerful cryogenic rocket engine developed to date. C25 and its engine in particular had been the primary reason for GSLV Mk. III falling seven years behind its original project schedule and all eyes were on the screens at Mission Control displaying the launcher's trajectory as the third assumed control of propulsive flight.

Per the original flight plan, the C25 cryo stage was planned to fire for ten minutes and 43 seconds to accelerate the stack by 5.8 Kilometers per second to reach the planned injection speed of 9.8 km/s. However, Launch Control displays showed a not insignificant overperformance, meaning the stage was accelerating faster than predicted through mission simulations.

This in itself is not uncommon especially for a completely new rocket stage for which only theoretical performance models exit.

However, it requires a guidance system capable of detecting the overperformance and adjusting the flight path to reach the proper orbit and shut the engine down early once the desired injection speed/orbit are reached.

GSLV Mk. III (http://spaceflight101.com/spacerockets/gslv-mk-iii/) appeared to do just that, ending the CE-20 burn after ten minutes and 24.8 seconds – 18 seconds earlier than was planned per the pre-flight prediction. The satellite separated as expected 15 seconds after the end of powered flight and GSLV Mk. III's first orbital mission was declared a full success.

Initial tracking elements provided by the Joint Space Operations Center showed GSAT-19 in an orbit of 158 by 34,579 Kilometers, inclined 21.55°. This orbit was over 1,000 Kilometers short on apogee compared to the planned injection orbit of 170 by 35,975 Kilometers, 21.5°. In terms of change in velocity, GSAT-19 needed an additional 15m/s to make up for the shortfall – not particularly dramatic, but enough to change the planned orbit-raising scheme that called for three maneuvers to be carried out around apogee to circularize the orbit and reduce the orbital inclination to zero in order to put the craft into a drift orbit near GEO.

This plan was changed and a supplementary maneuver was ins erted to make up for the off-target injection. GSAT-19 fired up its Liquid Apogee Motor at 8:33 UTC on Tuesday when passing the low point of its orbit in order to raise the apogee to what was expected at orbital insertion. The 116-second firing of the 440-Newton LAM changed the vehicle's velocity by ~16m/s and placed GSAT-19 into an orbit of 173 x 35,938 Kilometers.

From there, the satellite continued as planned with a three-burn GEO transfer. LAM fired up again at 10:14 UTC on June 7 for a lengthy burn of 5538 seconds that changed the craft's velocity by around 900m/s and put it into an orbit of 10,287 by 35,840 Kilometers at an inclination of 7.02 degrees. The next burn was 3469 seconds in duration and began at 4:25 UTC on June 9, providing a delta-v of just over 700 meters per second and placing the satellite in a 30,208 by 35,875-Kilometer orbit, inclined 0.79 degrees.

The third and final orbit-raising maneuver occurred at 2:29 UTC on Saturday, June 10 and lasted 488 seconds for a delta-v of around 110 meters per second, boosting the satellite into a Geostationary Drift Orbit of 35,470 x 35,869 Kilometers, inclined 0.1 degrees. ISRO also confirmed on Saturday that GSAT-19 successfully deployed both of its solar arrays at 10:45 UTC followed by the deployment of the two antenna reflectors and the acquisition of three-axis control by 14:12 UTC.

GSAT-19 is now se t for a period of orbital fine-tuning to enable the satellite to become fully stationary at its initial orbital location.

In terms of propellant reserves for the operational mission of the craft, the supplementary maneuver needed due to the slightly off-target injection will have negligible or no consequences at all. Conservative calculations show GSAT-19 consumed around 1,360 Kilograms of propellant firing the LAM engine, plus a smaller quantity spent for attitude control, leaving at least 300kg of propellant onboard the satellite which will be sufficient for almost 12 years of stationkeeping maneuvers. GSAT-19 has been designed for a nominal service life of 10 years.

Nevertheless, the slightly off-target delivery means work for ISRO's engineers, now tasked with tweaking GSLV's guidance algorithm – taking into account actual performance numbers of C25 for future missions and refining the vehicle's response to changes in performance in flight to ensure future missions will accomplish more accurate injections.

ISRO will eventually switch all of India's satellite launches to its own launchers and also plans to offer rides on both GSLV versions on the commercial market once the vehicles have fully proven themselves. For the Mark III variant, the next mission won't come until 2018 with a tentative launch date in January with the GSAT-20 satellite that will debut a new satellite platform and put GSLV's enhanced performance to the test.

GSAT-19 is now ready to head into testing before beginning operational services with a high-throughput Ka/Ku-Band payload to support data-intensive telecommunications with a total capacity of 4Gbps. The satellite also hosts a number of advanced satellite technologies like Indian-built Li-Ion batteries, miniaturized heat pipe technology for more efficient thermal regulation, fiber-optic gyros for attitude determination, Micro Electro-Mechanical (MEMS) accelerometers, and a Ku-Band telemetry/telecommand transponder.
