Japan is preparing an H-IIA rocket for liftoff on Thursday with the second Quasi-Zenith Satellite to help augment Global Positioning System services over the Japanese Islands and the Asia Pacific Region by increasing GPS availability and accuracy. The launch of QZS-2 opens a push to establish the operational four-satellite constellation by the end of this year with two more satellites headed uphill on H-IIA rockets later in 2017.

Liftoff fr om the picturesque Tanegashima Space Center is planned at 0:17 UTC on Thursday, 9:17 a.m. local time on the southern tip of the country fr om where H-IIA will head south-east across the Pacific Ocean to accomplish a high-energy injection into an elliptical transfer orbit. H-IIA will drop its two Solid Rocket Boosters less than two minutes into the flight and fire its LE-7A engine for six and a half minutes before the LE-5B engine of the second stage takes over for a pair of burns. The 4,100-Kilogram QZS-2 satellite will be sent on its way 28 minutes after liftoff.

The Quasi-Zenith Satellite System (QZSS) entered development in 2002 with the aim of increasing the availability of GPS navigation services for the Japanese territory, in particular the country's urban canyons where buildings block all GPS satellites that are not at high elevation, potentially causing interruptions in service. To that end, QZSS proposed to establish a three-satellite constellation in a specialized orbit that places one satellite directly over Japan at any given time.

The QZSS satellites are designed to deliver two types of signals – GPS-compatible navigation signals and GPS augmentation messages that can be used by ground receivers to more accurately calculate user position. Through the GPS-compatible messages in the L1, L2 and L5 bands, the QZSS satellite can be treated as an additional member of the GPS constellation at high elevation angle fr om all locations in Japan, increasing availability of GPS.

Illustration of GPS Availability Enhancement in Japan's Urban Canyons – Image: JAXA

The GPS augmentation approach followed by QZSS is similar to that of the U.S. Wide Area Augmentation System in that a number of ground stations monitor variability in GPS signals – caused by clock errors and ionospheric delay – and provide correction messages to a high-altitude satellite that immediately relays them to augmentation-enabled receivers on the ground to increase location accuracy to around one meter.

The first QZS satellite launched atop an H-IIA rocket in October 2010 and completed several months of signal characterization and fine tuning before all signals were moved into active operation in July 2011. Studies have shown that GPS accuracy has been improved by a factor of up to 2.5 when QZS-1 is overhead and transmitting augmentation code – clearing the system to move from a proof-of-concept into operational services.

After successful demonstration of the QZSS principle, JAXA ordered three satellites from Mitsubishi Electric in 2013 for a total of $526 million, expanding the planned three-satellite constellation with another satellite that will reside in Geostationary Orbit and provide augmentation services for the entire Asia-Pacific Region.

Based on the DS-2000 satellite platform, QZS-2 stands 6.5 meters tall and weighs in at 4,100 Kilograms, comprising a 1,180-Kilogram satellite platform, 370kg navigation payload and 2,450kg of maneuvering propellant. At the heart of the satellite sits a pair of redundant Rubidium Atomic Clocks that provide the ultra-stable timing needed in the generation of regular GPS navigation messages. Japan received clearance from the U.S. in 2006 to use the GPS navigation bands as well as the L1-SAIF augmentation signal architecture.

QZS-4 will be an identical carbon copy of the second satellite and complete the three-satellite constellation in what is known as a Tundra orbit that allows one of the satellites to be almost directly overhead (zenith) as seen from a user in Japan. The QZS-3 satellite will be slightly heavier, weighing in at 4,700 Kilograms, and aiming for a 15-year mission in the traditional Geostationary Orbit from wh ere it can relay augmentation messages to a large area.

GPS augmentation with sub-meter or meter-accuracy is primarily used in aviation but also finds application on the ground for mapping and agriculture. The QZSS constellation is also used to examine the behavior of atomic clocks in space.

QZSS takes a unique spot in the satellite spectrum in that it is designed to augment another satellite constellation but moves beyond acting as a bent-pipe relay of ground-generated augmentation signals and in-fact delivers navigation signals of its own. The QZSS constellation will also be capable of augmentation for the European Galileo navigation constellation that will become operational before the end of the decade.

QZSS itself will be fully operational by mid-2018 and JAXA plans to add another three satellites in the 2020s to further increase GPS availability in Japan's urban canyons.

H-IIA Assembly – Photo: MHI

The launch of QZS-2 will be the third flight of the H-II rocket family in 2017, having already lifted the DSN-2 defence communications satellite and IGS Radar-5 reconnaissance craft.

Rollout of the 53-meter tall H-IIA launcher is expected at 9:30 UTC on Wednesday, 18:30 local for a 500-meter trip from the Vehicle Assembly Building to Launch Pad 1 at the Yoshinobu Launch Complex. Meteorologists are predicting rain through the day on Wednesday but have no concerns for the evening rollout and overnight launch countdown.

Flying in its 202 configuration, H-IIA consists of a two-stage stack measuring four meters in diameter plus two SRB-A3 Solid Rocket Boosters on the first stage, generating the kick needed to send QZS-2 toward its high-energy orbit. H-IIA 202 has a launch mass of 285,000 Kilograms and can lift up to 4,100 Kilograms into a Geostationary Transfer Orbit.

Following activation and checkouts of the rocket, teams will press into propellant loading around seven hours and 45 minutes before the opening of the day's launch window, pumping 120 metric tons of -183°C Liquid Oxygen and -253°C Liquid Hydrogen into the two cryogenic rocket stages.

Computers will assume control of the countdown at X-4.5 minutes to take H-IIA through final preparatory steps such as the pressurization of tanks, the transition to internal power and the activation of the Flight Control System. The first stage's LE-7A engine will come to life at X-5.2 seconds for throttle-up and a brief moment of performance monitoring before the twin boosters ignite and catapult the rocket off the ground.

Liftoff is precisely timed for 0:17:46 UTC and H-IIA will race uphill with a total thrust of 685 metric-ton-force. The twin boosters deliver 78% of the total liftoff thrust as the H-IIA climbs away from its sea-side launch pad with the usual scream unique to Japan's H-II rockets.

H-IIA will make a brief vertical climb before executing its roll and pitch program to achieve the planned ascent trajectory – flying south-east for a trip across the Pacific. Unlike a typical geostationary delivery that aims to reduce orbital inclination, H-IIA will be targeting a higher inclination than its launch site as the QZS constellation satellites operate in an orbit inclined 44 degrees to either side of the equator.

The two boosters fly in a special configuration with a shorter burn time, but higher thrust – optimized for a GTO-type mission profile. Each of the twin boosters will be delivering 281,200-Kilogram force of thrust over the course of a 98-second burn to accelerate the launcher to a speed of 1.5 Kilometers per second.

The declining pressure on the boosters will be detected via sensors and separation will be commanded at T+1 minute and 48 seconds when H-IIA will be 54 Kilometers in altitude. The 15-meter long boosters will be jettisoned pyrotechnically, swinging away from the rocket along their thrust struts to ensure a clean separation.

>>Ascent Profile (http://spaceflight101.com/h-iia-qzs-2/flight-profile/)

Image: JAXA/Spaceflight101

With the boosters gone, H-IIA will rely on its LE-7A for another five minutes, consuming 260kg of cryogenics per second to boost the vehicle into space with a vacuum thrust of 109,300 Kilogram-force.

The protective payload fairing will be separated four minutes and ten seconds into the flight when H-IIA will have reached an altitude of 151 Kilometers wh ere aerodynamic forces are no longer a concern for the satellite.

The first stage will continue operation until T+6 minutes and 38 seconds, boosting the stack to a velocity of 5.2 Kilometers per second. Stage separation occurs eight seconds after cutoff at an altitude of 239 Kilometers as pyrotechnics severe the connection between the stages and springs push the 37-meter long Core Stage away.

The LE-5B engine of the second stage will ignite six seconds after stage separation, soaring to a thrust of 13,970 Kilogram-force for a burn of five minutes and 42 seconds to lift the stack into a Low Earth Parking Orbit. At the conclusion of the first burn of the second stage, the stack will enter a coast phase of exactly 12 minutes to set up the proper insertion conditions for the second burn that aims to significantly boost the high point of the orbit.

QZSS Operational Orbit – Image: JAXA

Re-start of the LE-5B is expected 24 minutes and 34 seconds into the mission and the engine will be tasked with increasing the vehicle's speed by 2.5 Kilometers per second over the course of a firing of three minutes. QZS-2 is targeting an orbit of 250 by 31,600 Kilometers at an inclination of 31.9 degrees from wh ere it will use its own engine to reach the operational QZS orbit of 32,600 by 38,950 Kilometers, inclined 44 degrees with the high point positioned over Japan to allow the satellite to spend the majority of its orbit at an elevation of 60° or higher as seen from Japan.

Loaded springs will send QZS-2 on its way 28 minutes and 24 seconds into the mission, marking the start of its first steps in orbit that include a stabilization of its orientation, the start of communications with the ground and a series of health checks. Over the course of several days, the satellite will fire its main engine to take its position in the QZS constellation at the proper spacing to QZS-1.

A Japanese H-2A rocket is set for launch Thursday with the country's second navigation satellite, growing a network of beacons in the sky to give emergency responders, security forces and the public more accurate positioning and timing signals in Japan and neighboring regions.

Спойлер

Japan's second Quasi-Zenith Satellite, nicknamed Michibiki 2, will join a similar craft launched in September 2010 to improve navigation in the country, augmenting signals broadcast by the U.S. military's Global Positioning System.

The Michibiki 2 satellite is set to blast off on top of an H-2A rocket at 0017:46 GMT Thursday (8:17:46 p.m. EDT Wednesday) from Launch Pad No. 1 at the Yoshinobu launch complex at the Tanegashima Space Center, Japan's primary spaceport at the southwestern edge of the country's main islands.

Liftoff is timed for 9:17 a.m. Japan Standard Time, when the 174-foot-tall (53-meter) H-2A rocket will fire its hydrogen-fueled main engine and two strap-on solid rocket boosters and soar toward the east over the Pacific Ocean.

Ground crews rolled out the H-2A rocket from its assembly building at the Tanegashima Space Center a few hours ago.

Спойлер

The rocket was fixed on top of a mobile launch tower for the 1,600-foot (500-meter) journey to Launch Pad No. 1, which took about a half-hour to complete.

The rollout began around 1000 GMT (6 a.m. EDT; 7 p.m. Japan Standard Time).

Technicians planned to plug the launch platform into ground electrical and propellant supplies before fueling begins in the final hours of the countdown. Since the rocket's arrival at the pad, the launch team has given the "go" to begin filling the H-2A with liquid propellants.

Once the launch team checks out the rocket's systems and loads it with cryogenic liquid hydrogen and liquid oxygen, an automated countdown sequencer will take over the final steps before liftoff.

Launch is scheduled for 0017:46 GMT Thursday (8:17:46 p.m. EDT Wednesday) with the Michibiki 2 navigation satellite.

Now less than 60 minutes from the planned launch of the H-2A rocket.

Спойлер

Officials just gave the "go" to enter the terminal count, which began at 2317 GMT. The final hour of the countdown will prepare the rocket, the payloads, and ground systems for flight.

The H-2A rocket for today's launch is flying in the "202" configuration with two large 15-meter-long (49-foot) solid rocket boosters and without any of the smaller strap-on boosters sometimes used to augment the launcher's thrust.

It also features a standard four-meter (13.1-foot) diameter nose shroud, which encloses the Michibiki 2 spacecraft for the first few minutes of flight through the lower atmosphere.

The lead contractor for the H-2A rocket is Mitsubishi Heavy Industries.

T-minus 20 minutes. Engineers are uploading the latest upper level wind data into the H-2A's flight computer. The rocket will use the information to compute a specific steering profile based on the real launch day weather conditions. 

At liftoff, the H-2A will be propelled upward from the launch pad on the power of a single hydrogen-burning LE-7A main engine and two solid rocket motors. The total liftoff thrust of the rocket is approximately 1.4 million force pounds. 

The rocket will pitch east from Tanegashima, racing through the speed of sound in less than a minute and reaching an altitude of more than 30 miles in the first two minutes of flight. 

After consuming their pre-packed solid propellant, the two strap-on boosters will jettison at about the two-minute point. The 13.1-foot diameter payload shroud will separate at T+plus 4 minutes, 10 seconds after the H-2A rocket ascends above the discernable traces of Earth's atmosphere. 

First stage main engine cutoff, stage separation and ignition of the second stage's LE-5B engine will occur nearly seven minutes into the mission. The second stage will burn for nearly six minutes before shutting down at T+plus 12 minutes, 34 seconds. 

After a 12-minute coast, the second stage will reignite for a 3-minute burn.

Deployment of the Michibiki 2 satellite is expected at T+plus 28 minutes, 24 seconds.

ЦитироватьЯпония запустила ракету со спутником связи "Митибики"
ТОКИО, 1 июня. /Корр. ТАСС Алексей Заврачаев/. Японское агентство аэрокосмических исследований (JAXA) провело запуск второго по счету спутника связи "Митибики" с помощью тяжелой ракеты-носителя H-2A. Трансляция старта с космодрома Танэгасима в юго-западной префектуре Кагосима велась в прямом эфире. 
Запуск прошел успешно, сообщила компания Mitsubishi Heavy Industries, занимающаяся производством H-2A.
Спутник отделился от ракеты на высоте 275 км над поверхностью Земли и продолжил движение по заданной траектории.
Первый такой аппарат был выведен на орбиту в сентябре 2010 года, а до конца текущего года будет запущено еще два спутника. По плану правительства Японии, к 2018 году четыре японских спутника будут использоваться для дополнения американской системы глобального позиционирования GPS, поскольку иногда пользователи испытывают затруднения при плохом сигнале в труднодоступных местах.
Особенность этой системы - в высокой степени шифрования сигналов. Это дает возможность, как утверждается, надежно защитить их от помех, которые могут создавать враждебные государства или террористические организации. Помимо гражданских пользователей, на "Митибики" предполагается полностью переключить вооруженные силы и спецслужбы Японии.
К 2023 году группировку "Митибики" на орбите планируется увеличить до семи аппаратов, что позволит, в случае необходимости, полностью отказаться от GPS и создать собственный аналог под названием QZSS. Также японские спутники, которые будут находиться на высокой эллиптической орбите, смогут обеспечить более точное позиционирование с погрешностью всего три сантиметра. Для сравнения, у системы GPS этот показатель составляет порядка 10 метров.
Благодаря этому японские власти рассчитывают приступить к активному внедрению беспилотных технологий управления автомобилями, сельскохозяйственной техникой и т.д. Эти меры необходимы в связи с постепенным старением общества и сокращением работоспособного населения в Японии.

• Satellite Positioning, Navigation and Timing Service
• Centi-meter Level Augmentation Service (CLAS)
  

The trial services will offer services with the same performance as the operation starting in FY2018 (*).The details are shown on this website's User Interface Specifications page.

Until now, Centi-meter Level Augmentation Service has been providing and broadcasting augmentation information that is available in whole coverage area of QZSS to the verification users. From now on, the trial services will offer service with the same performance as the operation starting in FY2018 (*), because the adjustment for the function cooperating with domestic reference station network for the rapid acquisition of centi-meter level accuracy has been finished. In addition, IS-QZSS-L6 is updated on this web.

(*) Centi-meter Level Augmentation information trial service starts to broadcast augmentation information for the following GNSS signals shown on this website's Performance Standard (PS-QZSS), 6.1 clause.

QZSS: L1C/A, L2C
GPS: L1C/A, L2P

About Centi-meter Level Augmentation information using other signals, it is planned to be broadcast after the confirmation is completed about CLAS performance depending on GNSS constellation status and the correspondence to GNSS of GEONET. Notice will be posted on this website about the start date of that service and other issues.
