Sky is not the limit for cooperation
The ‘South Asia Satellite’ will provide a full range of applications (Very Small Aperture Terminals; Direct-to-home services; Tele-medicine; Tele-education; Broadcast; Meteorological; Disaster management support etc) and services to all of India’s neighbo
Prime Minister Narendra Modi tweeted ‘Launch of the South Asia Satellite shows that for South Asia, even the sky is not the limit for cooperation!’ Indeed, the sky is not the limit. While the Indian Space Research Organisation (ISRO) has shown its mettle to the world since many years, it has got an added boost with the government led by the Prime Minister, Narendra Modi. It was during the run-up to the Indian general elections in 2014, Prime Minister Modi had indicated that the foreign policy will actively focus on improving ties with the immediate neighbours. After the landslide victory in the general elections, Modi invited all heads of State/heads of government of SAARC countries to his swearing-in ceremony as the Prime Minister.
In 2014, after a month in government, Prime Minister Modi asked ISRO to develop a SAARC satellite. He asked the scientists to work on a satellite that would provide a full range of applications (Very Small Aperture Terminals – VSAT; Direct-to-home – DTH services; tele-medicine; tele-education; broadcast; meteorological; disaster management support, etc) and services to all of India’s neighbours. Prime Minister Modi had then said ‘There is a lot of poverty in the SAARC nations and we need scientific solutions for this.”
And ISRO, as is its prowess, showed that it could rise up to any occasion. In 1975 India became the first South Asian nation to launch a satellite. The ISRO Chairman, A.S. Kiran Kumar had stated that the satellite can be launched within 18 months of receiving approval from the SAARC member nations. It was proposed to build a satellite with 12 Ku-band transponders (36 Mhz each) and launch using the Indian Geosynchronous Satellite Launch Vehicle (GSLV) Mk-II. The total cost of launching the satellite was estimated at ` 235 crore, and the cost of the launch to be met by India.
Pakistan and Afghanistan back out
The countries participating, besides India, are Bangladesh, Bhutan, Nepal, Maldives and Sri Lanka. These countries will only have to pay for their ground stations; all other costs are being borne by India. Instead of being called SAARC satellite it is called South Asia satellite as Pakistan and Afghanistan backed out of this venture, the former fearing that India could use the satellite for stealth surveillance. Afghanistan wanted more transponders as it has leased a satellite from Eutelsat and was going to place in the same longitude as GSAT-9. Nepal has also plans of acquiring two communications satellites of its own.
Bangladesh signed into the pact only recently. It was worried about a clash in frequency allocation with its impending Bangabandhu 1 communications satellite. However on March 23 this year, ahead of Prime Minister Sheikh Hasina’s visit to India, Bangladesh signed up for the programme. As regards Sri Lanka, it signed up after India agreed to not prevent it from launching its own communications satellite in the future.
In this background, the May 5, 2017, launch of the 2,230 kg South Asia Satellite GSAT-9 into a Geosynchronous Transfer Orbit (GTO) is historic. The GSLV-F09 mission is the eleventh flight of India’s Geosynchronous Satellite Launch Vehicle (GSLV) and its fourth consec- utive flight with the indigenous Cryogenic Upper Stage (CUS). The vehicle is designed to inject 2-2.5 tonne class of satellites into GTO. The overall length of GSLV-F09 is 49.1 m. GSLV-F09 was launched from the Second Launch Pad (SLP) at Satish Dhawan Space Centre SHAR (SDSC SHAR), Sriharikota, the space port of India.
GSLV-F09 vehicle configuration including the CUS is similar to the ones successfully flown during the previous three missions – GSLV-D5, D6 and F05 – in January 2014, August 2015 and September 2016 respectively. GSLV-D5 and D6 successfully placed two communication satellites –GSAT-14 and GSAT-6, while GSLV-F05 placed India’s weather satellite INSAT-3DR, in the intended GTOs. S-band telemetry and C-band transponders enable GSLV-F09 performance monitoring, tracking, range safety/flight safety and Preliminary Orbit Determination (POD).
GSAT-9 is configured around the ISRO’s standard I-2K bus. The two solar arrays of GSAT-9 consisting of Ultra Triple Junction solar cells generate about 3,500 Watts of electrical power. Sun and Earth sensors as well as gyroscopes provide orientation reference for the satellite. The Attitude and Orbit Control System (AOCS) of the satellite maintains it’s orientation with the help of momentum wheels, magnetic torquers and thrusters. The satellite’s propulsion system consists of a Liquid Apogee Motor (LAM) and chemical thrusters using liquid propellants for initial orbit raising and station keeping. The satellite also carries plasma thrusters, assisting in station keeping.
India’s advancements in space are highly commendable and the neighbouring countries can benefit from it. India can also share the know-how and knowledge from its Indian Regional Navigation Satellite System (IRNSS), the GPS-Aided GEO-Augmented Navigation (GaGAN) networks and the CartoSat imaging satellites, while ensuring that it does not compromise with its own strategic interests. Regional cooperation has gone on to a higher level!
