ISRO to launch GSAT-30 satellite

On January 17, 2020, the Indian Space Research Organization will launch GSAT-30 satellite on the launch vehicle Ariane-5. It is to be launched in Ariane Launch Complex at Kourou. Kourou is a French territory that if located along the north eastern coast of South America.

About the Mission

The GSAT-30 is a communication satellite. It is to replace INSAT-4A. The mission life of GSAT-30 is 15 years. ISRO has designed GSAT-30 in such a way to increase the number of transponders. A transponder is a device that transmits and responds to signals.

The satellite will help in supporting VSAT network, teleport services, DTH televisions services, cellular backhaul connectivity and digital news gathering services

INSAT-4A

The Indian National Satellite System was a series of geostationary satellites that were launched for telecommunications, meteorology, broadcasting and search and rescue operations. The INSAT-4A was launched in 2005  mainly for communication purposes.

Ariane

Ariane Space is a commercial satellite launching organization that was founded in 1980. Since then, it has launched 23 Indian satellites. APPLE Experimental was the first Indian satellite to be launched by Ariane.

The launch centres of the organization is located in Washington D.C, Tokyo, Singapore, French Guiana and Baikonur Cosmodrome (Central Asia)

APPLE

APPLE was an experimental satellite launched by India in 1981. It was the first experimental communication satellite of India. It was used for TV and radio communications. It laid the foundation for the large satellite constellation of India that included INSAT and GSAT series.

ISRO successfully launches GSAT-17 Satellite

ISRO has successfully launched GSAT-17 communication Satellite onboard the Ariane-5 launch vehicle from the Guiana Space Center at French Guiana on June 28. GSAT-17 will be the ISRO’s third satellite that is launched within a span of three months.

Salient Highlights

The 3,477-kg GSAT 17 communication satellite will be placed in the geostationary orbit and will have a mission life of 15 years.

The satellite will be an addition to the current fleet of 17 Indian communication satellites that are already providing services from space.

Apart from providing communication services, the satellite will provide meteorological and satellite-based data to help rescue services which were earlier provided by geostationary satellites called Indian National Satellite System (INSAT).

GSAT-17 will provide continuity of services of operational satellites in C, extended C and S bands

Once launched, ISRO’s Master Control Facility at Hassan in Karnataka and Bhopal in Madhya Pradesh will take over and place the satellite in geostationary orbit. GSAT-17 was designed and assembled at the ISRO Satellite Centre in Bengaluru.

In addition, GSAT-17 will also launch communication satellite Hellas Sat 3-Inmarsat S EAN. Hellas Sat 3 will provide directly to home television and telecom services across Europe, West Asia and South Africa. Inmarsat is set to provide in-flight Internet facilities for European airlines.

Launch Vehicle

As ISRO is yet to have a launcher that is capable of lifting payloads above 2,000 kg. ISRO has just started testing the GSLV-Mark III for this purpose.

GSAT-17 will be the 21st Indian launch for the Arianespace. ISRO’s upcoming GSAT- 11 which will weigh more than 5,000 kg will also be launched by Arianespace.
