The Indian Space Research Organisation (Isro) on Wednesday launched the country’s newest satellite GSAT-7A, which will give a boost to the defence forces’ communication capabilities, from Andhra Pradesh’s Sriharikota on Wednesday.

In the third mission in just over a month, the space agency launched the 2,250 kg operational communication satellite from the second launch pad of Satish Dhawan Space Centre at 4.10pm on Wednesday.

The satellite was carried by the Geosynchronous Satellite Launch Vehicle-F11 (GSLV-F11), Isro’s 35th communication satellite and the 13th flight of the GSLV rocket to orbit.

The GSLV-Mk II rocket launched the satellite into the temporary orbit after a flight of nearly 20 minutes. The rocket will be taken into the geostationary or circular orbit using the onboard propulsion system and it will take few days after the separation from the launcher to reach its orbital slot.

“GSLV F11 is Isro’s fourth generation launch vehicle with three stages. The four liquid strap-ons and a solid rocket motor at the core form the first stage. The second stage is equipped with high thrust engine using liquid fuel. The Cryogenic Upper Stage forms the third and final stage of the vehicle,” the space agency said on its website.

According to reports, GSAT-7A has been built exclusively for the Indian Air Force (IAF) and the Indian Army and will add to the forces’ communication capabilities.

The satellite will allow IAF to interlink its ground radar stations, airbases and airborne early warning and control (AWACS) aircraft, and reduce the reliance on on-ground control stations for drones, they said. It will also boost the air force’s network-dependent warfare capabilities, enhancing its abilities to operate globally.

Wednesday’s mission will be the space agency’s last mission for this year. This year, Isro launched GSAT-11 on December 5 on a European vehicle from French Guinea’s Kourou, GSAT-29 on November 14 on its GSLV-MkIII vehicle and the ill-fated GSAT-6A on March 29 from Sriharikota.

The launch of Chandrayaan-2 and the PSLV-C44 remote-sensing satellite launch are among the seven missions lined up in 2019.

India launches ‘heaviest’ satellite for internet access

India’s heaviest satellite has gone into orbit on a French rocket to help boost broadband internet services.

Weighing about 5,854kg (12,906lb), the GSAT-11 is India’s “most-advanced” multi-band communication satellite.

The Indian Space Research Organisation (Isro) launched the satellite from the Kourou spaceport in French Guiana early on Wednesday morning.

It will be placed in a geostationary orbit by the end of this month and its transponders will be switched on.

Isro chief K Sivan told reporters that the satellite will “play a vital role in providing broadband services across the country”.

Scientists say it will provide internet access to “off-grid” remote areas in India – hills and islands, for example – where traditional fixed-line broadband services are not available and would be helpful during emergencies and disaster relief. And it will also help provide internet connectivity during air travel in India.

India hired a French rocket to carry the satellite, which is expected to have a life span of 15 years, because it does not have a rocket to carry such a heavy payload.

There are more than 440 million internet users in India, and the number is expected to double by 2022.

However, slow speeds or lack of services still affect access in the remotest areas where is there is no cable connectivity.

India has emerged as a major player in the multi-billion dollar space market with dozens of communication and weather satellites in orbit.

In 2014, it successfully placed a space vessel in orbit around Mars, making it the first nation in the world to do so in its first attempt.

It also launched 104 satellites of varying sizes in one go in 2017, overtaking the previous record of 37 satellites launched by Russia in 2014.
