Bengaluru, December 5: The Indian Space Research Organisation (ISRO) on Wednesday successfully launched GSAT-11, India's heaviest satellite on board an Arianespace rocket from the French Guiana. The satellite blasted off from the Ariane Launch Complex in Kourou, a French territory located along the northeastern coast of South America. The launch was broadcast live on Doordarshan. ISRO Successfully Launches HysIS, India’s Earth-Mapping Satellite on PSLV-C43 From Sriharikota.

Reports inform that the GSAT-11 satellite is aimed to boost broadband services by providing something like 16 Gbps data link services to the country. ISRO claimed that the satellite is the heaviest and most-advanced high throughput communication satellite. "The heaviest, largest and most powerful satellite ever built by India is successfully launched by Ariane-5 today," ISRO Chairman K Sivan said soon after the launch. GSAT-11: ISRO Set to Launch India's Heaviest Communication Satellite in Space.

Sivan added saying that the GSAT-11 satellite is a next generation "high throughput" communication satellite configured around the ISRO's I-6K Bus with a designed lifetime of more than 15 years. According to ISRO, the satellite will provide high data rate connectivity to users of the Indian mainland.

Here's all you need to know about the GSAT-11 satellite:

  1. The GSAT-11 satellite weighs about 5,854 kg, the GSAT-11 is the "heaviest" satellite built by ISRO. It has been designed for a lifetime of more than 15 years.
  2. The Ariane-5 vehicle injected the GSAT-11 into the orbit in a flawless flight lasting about 33 minutes.
  3. GSAT-11 will provide high data rate connectivity to users of Indian mainland and islands through 32 user beams in Ku-band and 8 hub beams in Ka-band.
  4. GSAT-11 is going to be the "richest space asset" for India, the ISRO Chief said.
  5. The satellite has 38 spot beams as well as eight sub-beams, which would cover the entire country, including the remote places.
  6. The satellite will provide something like 16 Gbps data link services to the country.
  7. The satellite will play a vital role in providing broadband services across the country and also be a platform to demonstrate new generation applications.

The satellite will be initially placed in the Geosynchronous Transfer Orbit and later raised to Geostationary Orbit by firing the on-board Liquid Apogee Motor. After the separation phase, ISRO's Master Control Facility at Hassan, in Karnataka, took over the command and control of GSAT-11 and found its health parameters normal, the space agency said in a statement.
