A 28-hour countdown for the launch of the South Asia Satellite or GSAT-9 commenced, the Indian Space Research Organisation (ISRO) announced. According to ISRO, the countdown began at 12.57 p.m. The Geosynchronous Satellite Launch Vehicle (GSLV-Mk II) carrying the GSAT-9 is expected to blast off from the second launch pad at Satish Dhawan Space Centre in Sriharikota, Andhra Pradesh.

The GSAT-9 is being launched with an objective to provide different communication applications in Ku-band with coverage over South Asian countries, the ISRO stated. On Sunday, Prime Minister Narendra Modi said the South Asia Satellite, will go a long way in addressing the region's economic and developmental priorities.

"The capacities of this satellite and the facilities it provides will go a long way in addressing South Asia's economic and developmental priorities," he said in his monthly radio address 'Mann Ki Baat'. "Natural resources mapping, telemedicine, the field of education, deeper IT connectivity or fostering people-to-people contact, this satellite will prove to be a boon in the progress of the entire region."

"It is an important step by India to enhance cooperation with the entire South Asia...It is an invaluable gift. This is an appropriate example of our commitment towards South Asia. I welcome all the South Asian countries who have joined us on this momentous endeavour," he had said.

The space agency said that the GSAT-9 is configured around the ISRO's standard I-2K bus, with a lift-off mass of 2,230 kg, and the satellite's main structure is cuboid in shape built around a central cylinder with a mission life of more than 12 years. According to an official, ISRO on experimental basis decided to have electric power for the satellite. ALSO READ: ISRO's solar hybrid electric car completes successful test drive

"We have not reduced the volume of the traditional on-board fuel because of the electric power. We have added electric power facility to check its performance for use in future satellites," the official told IANS. He said the next satellite with electric power will be the GSAT-20 slated for launch next year.

Meanwhile, the ISRO is also gearing up to launch its heaviest rocket GSLV-Mk III later this month.

No media glare for South Asia Satellite

Special Correspondent

BENGALURU May 04, 2017 21:43 IST Upd ated: May 04, 2017 21:44 IST

ISRO has been unusually reticent about its launch from Sriharikota today
 
A communication spacecraft, the South Asia Satellite, which will serve India and six of its regional neighbours, is se t to lift off from Sriharikota off Andhra Pradesh on Friday evening.

Some bare information on this regional diplomatic overture apart, mystery shrouded the civil mission until late on the eve of the launch. The 2230-kg spacecraft will be launched on a GSLV, the Indian Space Research Organisation's medium-lift rocket, numbered F09.

A normally transparent ISRO has been unusually reticent about a less than routine launch. The time of the launch has a cryptic clue - one must infer it as 4.57 p.m. from the duration of the countdown. There will be no live telecast. Brochures that would be routinely released about five days ahead of a mission are still to be uploaded on the ISRO website.

Спойлер

Mediapersons will not cover a launch for the first time in a decade; normally ISRO would ferry about 200 reporters from different places to Sriharikota to witness a launch. This would be the fourth time in the history of Indian space launches, recalled T.S. Subramanian, veteran journalist with The Hindu's group publication, Frontline, who writes on Space and Defence and who has not missed an ISRO launch since 1980.

Among the three earlier exceptions was the launch of of Israel's spy satellite, TecSAR, on a PSLV in January 2008.

ISRO functionaries said, "This is our mandate. We don't know much about all this, either."

GSAT-9 was planned years ahead to augment Internet broadband and DTH activities within the country.

It is not known if Prime Minister Narendra Modi, who offered the spacecraft for the region, or dignitaries from those nations will witness the launch.

This much is known: a 28-hour countdown began for the GSLV mission at 12.57 p.m. on Thursday, along with other pre-launch activities, according to the space agency's one-liner put out in the afternoon.

GSLV-F09 is slated to take off with the 2,230-kg satellite at 4.57 p.m. on Friday.

The communication spacecraft carries 12 Ku-band transponders that can drive telecommunication, disaster management, broadcasting and direct to home TV, Internet activities, tele-education and telemedicine across the region.

India is gearing up for the country's second orbital space launch of the year on Friday, involving a Geosynchronous Satellite Launch Vehicle Mk.II delivering the GSAT-9 communications satellite to orbit to support television distribution over India and other Asian countries as well as augmenting space-based navigation data to allow aircraft to more accurately navigate through Indian airspace.

GSLV Mk.II is targeting liftoff at 11:27 UTC on Friday fr om the Second Launch Pad at the Satish Dhawan Space Center on India's east coast. Firing up its powerful solid-fueled core stage and four liquid boosters, GSLV will be headed to the south east to reach an elliptical Geostationary Transfer Orbit after firing its hypergolic second stage and cryogenic third stage to send the 2,230-Kilogram satellite on its way around 17 minutes after liftoff.

Friday's mission will be focused on the GSAT-9 satellite, also known as South Asia Sat. Built by ISRO based on the I-2K satellite platform, the spacecraft hosts twelve Ku-Band transponders that will deliver TV services over India and members of the South Asian Association for Regional Cooperation (SAARC). The satellite also carries India's fourth GPS Aided GEO Augmented Navigation (GAGAN) payload that delivers correction signals for aircraft navigation systems to increase navigation accuracy to three meters, assisting in air traffic management and landing in tough weather and challenging terrain.

GSAT-9 weighs in at 2,230 Kilograms and can therefore not be lifted by the PSLV rocket that maxes out at 1,500kg to a sub-GTO orbit. The satellite hosts a hybrid propulsion system relying on chemical propulsion for its climb into geostationary orbit and utilizing Xenon ion thrusters for stationkeeping in its GEO position at 48° East, validating the use of electric propulsion for future missions including all-electric satellites planned for launch in the coming years.

The 49-meter tall GSLV rocket was rolled from its assembly building to the Second Launch Pad at Satish Dhawan this week and a clean Mission Readiness Review cleared the vehicle to enter a 28-hour launch countdown that begins with filling the vehicle's boosters and second stage with storable propellants, UH25 Hydrazine and Nitrogen Tetroxide. Tanking on the upper stage occurs in the final hours of the countdown since the cryogenics have to be constantly replenished due to natural boil-off.

GSLV will come to life five seconds prior to liftoff when its four boosters are commanded to ignite followed by the ignition of the Core Stage to lift the rocket off the ground with a total thrust of 800 metric-ton-force.

Heading east across the Indian Ocean, GSLV's core stage will burn out after a minute and 46 seconds followed by the burnout of the boosters at T+2:29 when the rocket will already be 70 Kilometers in altitude, traveling 2.4 Kilometers per second. Stage separation between the solid-fueled core and the second stage occurs split seconds after booster shutdown using flexible linear shaped charges allowing the spent first stage and boosters to be pushed away by the exhaust of the second stage that ignites its engine at the moment of staging.


Image: ISRO

The protective payload fairing will separate shy of four minutes into the flight when the vehicle will have reached 115 Kilometers in altitude wh ere aerodynamic forces are no longer a threat to the delicate satellites structure.

Second stage shutdown comes at T+4:49 followed by stage separation 3.5 seconds later and Cryogenic Upper Stage ignition one second after that. India's cryogenic stage begins its burn in high-thrust mode providing 9,500kgf of thrust before reducing thrust to 7,500kgf for the remainder of the burn. The third stage will be up and running for nearly 12 minutes, accelerating the vehicle by close to 5 Kilometers per second to accomplish the GTO injection, targeting an orbit peaking at nearly 36,000 Kilometers in altitude.

GSAT-9 will be sent on its way just after passing T+17 minutes, tasked with deploying its solar arrays and contacting ground stations to be transferred to nominal mission mode ahead of a series of engine firings to maneuver into Geostationary Orbit for a service life of at least 12 years.
