India preps military communications satellite for launch Wednesday
December 18, 2018 | Stephen Clark

A communications satellite destined to serve the Indian military is set to blast off from the country's east coast Wednesday aboard a Geosynchronous Satellite Launch Vehicle on the seventh and last launch of the year for the Indian space program.

The GSLV Mk.2 is scheduled for liftoff at 1040 GMT (5:40 a.m. EST; 4:10 p.m. Indian Standard Time) Wednesday from the Second Launch Pad at the Satish Dhawan Space Center, located on Sriharikota Island on the Bay of Bengal approximately 50 miles (80 kilometers) north of Chennai.

The 26-hour countdown began Tuesday, and ground crews took steps to fill the rocket's second stage and four liquid-fueled boosters with storable hydrazine and nitrogen tetroxide propellants, according to the Indian Space Research Organization. In a reversal of the design of most launchers, the GSLV's core stage burns pre-packed solid propellant, while its strap-on boosters consume liquid fuel.

The GSLV's cryogenic third stage was scheduled to receive its load of super-cold liquid hydrogen and liquid oxygen in the final hours of the countdown Wednesday, ahead of the 167-foot-tall (51-meter) rocket on India's seventh launch of the year.

Several propulsion upgrades are flying on the GSLV Mk.2, including the second Indian launch with a High Thrust Vikas Engine on the rocket's second stage. The second stage also employs electromechanical actuators powered by lithium-ion batteries, replacing hydraulic systems used on past missions. The technology change will make the rocket more reliable, Indian officials said.

The second stage enhancements first flew on the GSLV Mk.2's most recent launch March 29, but Wednesday's mission will be the first to fly with an upsized cryogenic third stage, modified to carry 33,000 pounds of liquid hydrogen and liquid oxygen, around 6 percent more propellant than earlier GSLV Mk.2 third stages. That means the third stage on Wednesday's launch will fire more than a minute longer than the burn time on the previous GSLV Mk.2 flight in March, providing more lift capability for the rocket.

The GSLV Mk.2 will fire its liquid-fueled boosters at T-minus 4.8 seconds, run the strap-on Vikas engines through a health check, then command the solid-fueled core stage to ignite and propel the rocket off the launch pad.

Flying on nearly 1.8 million pounds of thrust, the GSLV Mk.2 will turn east from the Indian coast and climb into space over the Bay of Bengal. Its four boosters and core stage will shut down and drop into the sea around two-and-a-half minutes into the mission. The second stage's Vikas engine will take over and burn for around 2 minutes, 20 seconds, producing around 190,000 pounds of thrust — 6 percent more than the older Vikas engine design. The GSLV Mk.2's metallic payload shroud will jettison during the second stage engine firing, revealing India's GSAT 7A communications satellite once the rocket ascends into space.

The third stage's engine will ignite at T+plus 4 minutes, 55 seconds, at an altitude of 82 miles (133 kilometers). The cryogenic engine will do the rest of the work accelerating GSAT 7A into its planned orbit, and shutdown of the third stage is expected at T+plus 18 minutes, 57 seconds.

The 4,960-pound (2,250-kilogram) GSAT 7A spacecraft will separate from the GSLV Mk.2's third stage at T+plus 19 minutes, 12 seconds.

The GSLV Mk.2 will deploy the GSAT 7A satellite in an elliptical geostationary transfer orbit ranging between a low point of 105 miles (170 kilometers) and a high point of at least 20,623 miles (33,190 kilometers), although the rocket could place the payload in a slightly higher orbit, according to an ISRO brochure released for Wednesday's launch.

The Times of India, a major English-language newspaper in the country, reported that GSAT 7A will serve the Indian Air Force by connecting ground radar stations, airbases and airborne command and control aircraft. GSAT 7A will also support Indian Air Force drone operations, helping convert the military's remotely-piloted aircraft from ground control to satellite control networks.

The upgrades to the Indian military's drone control infrastructure comes as India acquires U.S.-built satellite-controlled drones, including armed Predator B or Sea Guardian drones capable of high-altitude, long-endurance missions, according to the Times of India.

GSAT 7A was preceded by the GSAT 7 satellite launched in 2013. It was built to provide communications for the Indian Navy.

In a press brochure released for Wednesday's launch, ISRO said GSAT 7A will provide Ku-band communications services over India during an eight-year design life. The spacecraft's solar panels will generate 3.3 kilowatts of electrical power once unfurled after launch.

Wednesday's mission will mark the seventh launch of a GSLV Mk.2 rocket with an Indian-built cryogenic upper stage since 2010. Five of the six GSLV Mk.2 flights to date have been successful, after a failure on the rocket's maiden launch in 2010 that Indian officials blamed on a pump failure on the upper stage.

GSLV-F11 successfully launches GSAT-7A

Indian Space Research Organisation's (ISRO) Geosynchronous Satellite Launch Vehicle (GSLV-F11) successfully launched the communication satellite GSAT-7A from the Satish Dhawan Space Centre (SDSC) in Sriharikota today.

The GSLV-F11 lifted off from the Second Launch Pad at SDSC at 04:10 pm IST, carrying 2250 kg GSAT-7A and about 19 minutes later, injected GSAT-7A into a Geosynchronous Transfer Orbit (GTO) of 170.8 km x 39127 km which is very close to the intended orbit.

An ISRO team lead by Chairman Dr K Sivan, Vikram Sarabhai Space Centre (VSSC) S Somanath, U R Rao Satellite Centre (URSC) Director P Kunhikrishnan, Space Applications Centre (SAC) Director D K Das, SDSC Director S Pandian, Liquid Propulsion Systems Centre (LPSC) Dr V Narayanan and ISRO Propulsion Complex (IPRC) Director T Mookiah witnessed the launch.

Mission Director Mohan M and Satellite Director Killedar Pankaj Damodar oversaw the launch proceedings.

Soon after the separation of the satellite, ISRO's Master Control Facility (MCF) at Hassan in Karnataka took over the command and control of GSAT-7A.The satellite's health parameters are normal.

In the next few days, scientists at MCF will perform various orbit-raising manoeuvres, using GSAT-7A's onboard propulsion system, to place the satellite in its final geostationary orbit.

In his post-launch televised address, Dr Sivan said the team has achieved another spectacular milestone by launching GSAT-7A.

"In the last 35 days, ISRO has successfully launched three missions from SDSC starting with GSLV MkIII-D2 on November14, PSLV-C43 on November 29 and finally GSLV-F11 today. GSLV has successfully injected GSAT-7A into a super synchronous transfer orbit," Dr Sivan said.

He said GSAT-7A is the heaviest satellite being launched by GSLV with an indigenously developed cryogenic stage.

"The cryogenic stage of this vehicle has been modified to increase the thrust rate. GSAT-7A is an advanced communication satellite with a Gregorian Antenna and many other new technologies. The testing and realisation of this satellite has been carried out meticulously by ISRO team. We have signed off year 2018 on a high and positive note," Dr Sivan added.

GSLV is ISRO's fourth generation launch vehicle with three stages. The four liquid strap-ons and a solid rocket motor at the core form the first stage. The second stage is equipped with a high thrust engine using liquid fuel. The cryogenic upper stage forms the third and final stage of the vehicle. GSLV-F11 was the seventh flight carrying indigenously developed cryogenic upper stage.

GSAT-7A is the 39th Indian communication satellite of ISRO to provide services to the users in Ku-band over the Indian region. Most of the functional requirements of the communication payloads and the other systems have been derived from ISRO's earlier geostationary INSAT/GSAT satellites.

Today's launch was the 7th mission of ISRO from SDSC in the year 2018. This was the 13th flight of GSLV-MkII.

Indian space program closes out year with launch of upgraded GSLV
December 19, 2018 | Stephen Clark

An upgraded Geosynchronous Satellite Launch Vehicle carrying more fuel and standing taller than earlier GSLV variants took off Wednesday fr om an Indian spaceport and delivered a new communications satellite to orbit for the Indian Air Force.

The GSLV Mk.2 rocket fired into space from the Satish Dhawan Space Center with nearly 1.8 million pounds of thrust at 1040 GMT (5:40 a.m. EST; 4:10 p.m. Indian Standard Time), soaring into a clear afternoon sky at the spaceport, located on India's southeastern coast just north of Chennai.

The rocket's solid-fueled core stage and four strap-on boosters consumed their propellants in the first two-and-a-half minutes of the flight, and a High Thrust Vikas Engine ignited with 190,000 pounds of thrust to continue the climb into orbit. The GSLV's cryogenic upper stage fired up around five minutes into the mission for a 14-minute burn.

Moments after shutdown of the hydrogen-fueled upper stage, the GSLV Mk.2 deployed the 4,960-pound (2,250-kilogram) GSAT 7A military communications satellite in a supersynchronous transfer orbit at 1059 GMT (5:59 a.m. EST). The upper stage engine was commanded to fire until it depleted its propellant supply, rather than targeting a specific altitude, to release the GSAT 7A satellite the highest orbit possible and reduce the spacecraft's fuel consumption to reach its final operational perch in geostationary orbit more than 22,000 miles (nearly 36,000 kilometers) over the equator.

K. Sivan, chairman of the Indian Space Research Organization, confirmed the successful outcome of the mission in remarks at the launch control center.

"Today, GSLV successfully and safely injected the advanced communications satellite GSAT 7A in a supersynchronous transfer orbit," Sivan said. "GSAT 7A is the third communications satellite India has launched in 35 days, and this is the heaviest satellite lifted by GSLV with the indigenous cryogenic stage.

A commentator on ISRO's live launch webcast reported the rocket placed GSAT 7A in an orbit with a perigee, or low point, of 106 miles (171 kilometers), an apogee, or high point, of 24,233 miles (39,000 kilometers), and an inclination of 19.37 degrees.

"We got 2,000 kilometers (1,200 miles) more than what we expected," Sivan said of the orbit achieved Wednesday. "That's a great achievement ... This success is going to increase or enhance the life of GSAT 7A."

GSAT 7A's on-board engine will maneuver the satellite into a circular geostationary orbit over the equator at 63 degrees east longitude, according to ISRO.

Wednesday's mission by the GSLV Mk.2 came after a rapid-fire pace of Indian space missions, beginning Nov. 14 with the second orbital test flight of the GSLV Mk.3 — India's biggest rocket — and followed Nov. 29 (Indian time) with the liftoff of a Polar Satellite Launch Vehicle with a hyperspectral Earth-imaging satellite and 30 secondary payloads. India's heaviest satellite, named GSAT 11, lifted off Dec. 4 aboard a European Ariane 5 rocket from French Guiana.

ISRO ends 2018 with seven successful space launches from India's spaceport, tying a record set in 2016 for the most Indian space launches in a year.

"This mission, both in the launch vehicle as well as the satellite, there are so many firsts," Sivan said. "The second stage propellant loading has been increased from 37.5 tonnes to 40 tonnes. In the cryogenic stage, the propellant loading has been increased from 12 tonnes to 15 tonnes, along with an enhanced thrust value in the cryogenic stage."

The GSLV mission Wednesday — designated GSLV-F11 — was the second launch with a High Thrust Vikas Engine on the rocket's second stage. The hydrazine-fed second stage also employed electromechanical actuators powered by lithium-ion batteries, replacing hydraulic systems used on past missions. The technology change makes the rocket more reliable, Indian officials said.

The higher-thrust engine and electromechanical actuators debuted on the GSLV Mk.2's previous flight March 29.

"This GSLV-F11 is not yet another GSLV but it is an improved version fo the GSLV, wh ere we have brought changes in the cryogenic stage as well as in the second stage of the vehicle to improve the payload capability," said S. Somanath, director of Vikram Sarabhai Space Center, headquarters for ISRO's launcher development programs.

The GSLV Mk.2 launched Wednesday stood 5.9 feet (1.8 meters) taller than earlier GSLV Mk.2 rockets to accommodate the extra propellants. Engineers had to analyze the aerodynamics and control behavior of the taller rocket before deeming it ready to fly, Somanath said.

"This is the sixth consecutive successful GSLV (Mk.2), and it shows that this vehicle is going to stay longer to make more missions in the years to come, with improved capability," Somanath said.

Future GSLV Mk.2 upgrades include a bigger payload compartment to accommodate larger satellites, according to Somanath. ISRO also plans to introduce the High Thrust Vikas Engine to the GSLV Mk.2's four strap-on boosters.

GSAT 7A will also support Indian Air Force drone operations, helping convert the military's remotely-piloted aircraft from ground control to satellite control networks.

The upgrades to the Indian military's drone control infrastructure comes as India acquires U.S.-built satellite-controlled drones, including armed Predator B or Sea Guardian drones capable of high-altitude, long-endurance missions, according to the Times of India.
