ISRO Gearing Up To Launch Risat Satellite For Border Surveillance On December 11


ISRO is on a launching spree now. The premier space agency successfully launched the Caartosat-3 satellite last week. Now, it is planning to launch another satellite, namely the Risat-2BR1. The Risat satellite is another radar-imaging Earth observation satellite, which is scheduled to launch from the Sriharikota launch pad on December 11.

ISRO Risat Satellite For Surveillance

The Risat satellite will take off aboard a PSLV-C48 rocket. The Indian Space Research aims to boost India's space-surveillance capabilities. Altogether, there are five Risat satellites, out of which one was launched earlier this year in May. After the launch of the Risat-2BR1, another Risat-2BR2 is expected to launch in the second half of this month.

At least four Risat satellites are required to orbit for security forces to keep strong surveillance on particular sensitive spots, an ISRO source told TOI. Going into the details, The Risat satellites are powerful and being dubbed as another 'eye in the sky' following the launch of the Cartosat-3 satellite launch.

According to the report, the Risat satellite is capable of seeing through the clouds and at night as well. The satellites will aid in 24 X 7 border surveillance, keep an eye on infiltration, and more importantly, on terror and anti-national group activities across the borders. The previously launched Risat satellites in 2016 were key to planning the surgical strikes in PoK.

ISRO Risat Satellite Launch

The ISRO Risat satellite is equipped with X-band SAR with a radial rib reflector of 3.6 meters mesh antenna. The "Risat-2BR1 has a powerful 0.35 meters resolution (two objects separated by 0.35 meters distance can be distinctly identified) and will cover a swath of 5 to 10 km," the source cites.

The Risat satellite will have a mission life of five years and will be placed around 560km altitude in the polar orbit. The satellite will also function as a weather satellite with the SAR to send clear images for disaster management, agriculture, and forestry.


At the same time, ISRO is will also launch QPS-SAR satellites developed by the Japanese company iQPS. There will also be four Lemur 2 CubeSats for the US company Spire Global joining the list of satellites. Furthermore, 2020 will be a year of more satellite launches as ISRO is planning to launch13 missions. The Chandrayaan-3 mission is also expected to take off in November 2020.
