New Delhi: Indian Space Research Organisation (ISRO) is set to launch India’s heaviest satellite weighing 5,854 kg from Europe’s Ariane-5 rocket early on December 5. The satellite launch is scheduled between 2.07 and 3.23 AM (IST), stated European space transporter Arianespace.
A report by The Times of India quoted ISRO chairman K Sivan as saying, “The launch of four high-throughput satellites will provide the country broadband connectivity of over 100 gigabits per second (Gbps) by next year.”
The satellite, which is scheduled for launch from French Guiana, will be placed in the Geosynchronous Transfer Orbit and then raised to geostationary orbit by firing the satellite’s onboard motor.
According to ISRO, GSAT-11 is the forerunner in a series of advanced communications satellites with multi-spot beam antenna coverage over Indian mainland and islands. The satellite with a mission life of 15 years will have 32 user beams (Ku band) and eight hub beams (Ka-band) and the throughput data rate of 16 Gbps.
GSAT-11 will play a vital role in providing broadband services across the country. Besides providing a platform to demonstrate new generation applications, the satellite will be used to meet the increased data demands with high data rates over regions using spot beams.
The satellite will support BharathNet connecting gram panchayat for e-governance and digital platforms; VSAT terminals and for enterprise network and consumer broadband applications.
“The satellites are powered by solar panels that charge the onboard batteries. The batteries are fully charged when the satellite is loaded on to the rocket,” said a space expert.
On 29 March, Indian rocket Geosynchronous Satellite Launch Vehicle (GSLV) slung GSAT-6A in its intended orbit. From there the satellite was to be taken up further to its orbital slot by firing its onboard motors.
The first orbit raising operation was successfully carried out by firing the onboard motors for around 36 minutes on 30 March morning.
The second orbit raising operation of GSAT-6A satellite was also successful as its motors were fired for about 53 minutes on 31 March.
After that, the communication link got snapped.
