Communication Satellite GSAT-30 will replace the aging INSAT-4A

Launch of GSAT-30

Context

The nation’s latest communication satellite, GSAT-30, was launched into space from the Guiana Space Centre in Kourou at 2.35 a.m. IST on 17th January 2020. The high-power satellite is equipped with 12 normal C band and 12 Ku band transponders.

The 3,357-kg satellite will replace INSAT-4A, which was launched in 2005 and marks the first mission of the year for Indian Space Research Organisation (ISRO).

What the GSAT-30 will do?

GSAT-30 will provide DTH [direct to home] television services, connectivity to VSATs [that support working of banks] ATMs, stock exchange, television uplinking and teleport services, digital satellite news gathering and e-governance applications. The satellite will also be used for bulk data transfer.

Why ISRO opted for a Foreign launch?

ISRO opted for a foreign launch as the GSAT-30 is much heavier than the 2,000-kg lifting capacity of its geostationary launch vehicle GSLV-MkII.

While the newer and more powerful GSLV-MkIII can lift up to 4,000 kg, the space agency plans to save the two or three upcoming MkIIIs for its first human space flight Gaganyaan of 2022 and two preceding crew-less trials, Dr. Sivan recently said.

About GSAT-30 Mission

GSAT-30 is a telecommunication satellite developed by the Indian Space Research Organisation (ISRO). The satellite’s main communication payload is 12 Ku band transponders for covering Indian mainland and islands and 12 C-band transponders for extended coverage over Asia and Australia. The satellite will act as a replacement for the defunct INSAT-4A. The satellite will provide advanced telecommunication services to the Indian subcontinent. It will be used for VSAT networks, television uplinks, digital satellite news gathering, DTH services and other communication systems. This is the 41st communication satellite launched by ISRO and the 24th launch of ISRO satellite by Arianespace.

The satellite is based on ISRO’s I-3K bus. It was assembled by a consortium of mid-sized industries led by Alpha Design Technologies Ltd. at ISRO Satellite Integration and Test Establishment at Bengaluru.

GSAT-30 satellite was launched aboard Ariane-5 launch vehicle (VA251) from French Guiana on 21:05 UTC ,16 January 2020 or 02:35 IST, 17 January 2020.
