ISRO launches the second Earth observation RISAT-2BR1 from Sriharikota on December 11: Report Technology News, Firstpost



Following the successful launch of the CartoSAT-3 last month the Indian Space Research Organization (ISRO) will be launching a surveillance satellite this month. The launch is reported to take place on December 1

1, according to a source associated with Times f Ind i a However, there is no official confirmation of the agency.

The Indian Space Agency will launch the Radar Imaging Satellite-2BR1 or the RISAT-2BR1. It is an advanced Earth observation and radar satellite that will join the RISAT-2B launched on May 22 of this year . It replaced RISAT-2, which was called a "spy satellite," as it was used to keep an eye on the terrorist camps along the Pakistani border.

Another satellite, the RISAT-2BR2, is due to launch later this month. It is said that ISRO will launch around four to five RISAT series satellites. "At least four RISAT space satellites are required to allow security forces to conduct daily surveillance at a specific location," sources said.

RISAT-2BR1 had a mission duration of five years and will be launched on PSLV. C48, ISRO's most widely used launcher. The launch will be from Sriharikota and, according to a report by OP India will take place in the polar orbit at a height of approximately 561 km.

The PSLV-C48 will also be carrying four Lemur 2 CubeSats for the US and two QPS SAR microsatellites being sent by a Japanese private company. These payloads are part of the deal that NewSpace India, the commercial arm of ISRO, has completed.

These satellites will help monitor borders around the clock by looking at the terrorist camps across the border. It will also help control infiltration and illegal entry and send pictures that will help to support land, forest and disaster management. The RISAT satellites are equipped with a synthetic aperture radar (SAR) to capture images of the Earth, day and night, and overcast.

The TOI report states that the satellite has an X-band synthetic-aperture (SAR) and radial aperture rib-reflector 3.6 m mesh antenna. "The radar system is a much more advanced Desi version of the Israeli TECSAR 1 system. RISAT-2BR1 has a powerful resolution of 0.35 m (two objects separated by a distance of 0.35 m can be clearly identified) and a range of 5 to 10 km. "

ISRO chief K Sivan recently announced that ISRO until March will be launched 13 missions . These include six rocket launches and seven satellite missions. However, he did not announce what the actual missions will involve.

By then, ISRO has conducted seven missions that were launched this year, including the much-discussed Chandrayaan 2, which was a partial success . The lander Vikram crashed into the moon a few minutes before his landing, killing every chance that the rover Pragyaan had. The orbiter was a success and is currently orbiting the moon.
