India’s national space agency, the Indian Space Research Organisation (ISRO), has successfully launched the GSAT-30, its heaviest communication satellite to date. The launch took place on January 17th, 2020 from the Guiana Space Centre in French Guiana using an Ariane 5 rocket. The GSAT-30, weighing 3,357 kilograms, will replace the INSAT-4A spacecraft services and provide communication services from geostationary orbit for a mission life of more than 15 years.
The GSAT-30 is equipped with 12 C-band and 12 Ku-band transponders, which are designed to provide high-quality television, telecommunications, and broadcasting services. The C-band covers the Indian mainland, the Andaman and Nicobar, and Lakshadweep Islands, while the Ku-band covers the Indian mainland and the Andaman and Nicobar Islands.
The launch of GSAT-30 is significant for India’s space ambitions as it aims to strengthen its communication capabilities. The satellite will help to expand broadband, digital satellite television and VSAT services across the country. It is also expected to serve as a platform for developing technologies such as demonstration of 6m S-Band Unfurlable Antenna and hand-held ground terminals.
ISRO has a busy schedule ahead, with plans to launch a total of 10 space missions in 2020. These include the Aditya-L1 mission to study the sun, the Gaganyaan manned mission, and the launch of GISAT-1, a geo-imaging satellite.
The GSAT-30’s successful launch comes after a hiccup in 2019 when the agency’s attempt to land a rover on the moon, Chandrayaan-2, ended in failure. Despite this setback, ISRO has continued to push forward in its space exploration efforts, marking its 50th year in 2019 and launching more than 300 foreign and Indian satellites into space since its inception.
Despite its achievements, ISRO continues to operate on a significantly smaller budget compared to other major space agencies. For instance, NASA’s budget for 2020 is $25 billion, while ISRO’s budget is around $1.8 billion. Despite its financial constraints, the agency has consistently demonstrated its capabilities in space technology and exploration, and the GSAT-30 launch is another testament to this.
