Isro will launch the Risat-2BR1 surveillance satellite along with 9 foreign sats on December 11

NEW DELHI: (Isro) will launch Risat-2BR1 radar images with the help of a rocket from 3:25 p.m. on December 11 to increase the country's space surveillance capacity.

PSLV-C48 will also launch nine commercial satellites: Israel (1), Italy (1), Japan (1) and USA. UU. (6), together with the main payload of the first launch pad of the Sriharkota spaceport next Wednesday. This will be the 50th mission of the PSLV.

Isro plans to launch four to five Risat series advanced satellites, of which one was launched on May 22 and the third after Risat-2BR1 will be launched in the second half of this month. Having four in space will help security forces stay in a particular place daily, a source in Isro said. The Risat satellite group, which can see through the clouds and also at night, will monitor the borders 24 hours a day, 7 days a week and help control infiltration and monitor terrorist activities across the borders . The images from the previous version of Risat were used to plan the surgical attack on terrorist launching platforms in Pakistan-occupied Kashmir in 2016.

Risat-2BR1 has an X-band synthetic aperture radar (SAR) with 3.6 m mesh antenna radial rib reflector. The radar system is an advanced version of the Israeli TECSAR 1 system. The satellite has a powerful resolution of 0.35 m (two objects clearly identified by 35 cm will be clearly identified) and will cover a 5 to 10 km strip. With a weight of 628 kg, Risat-2BR1 has a useful life of five years and will be placed at an altitude of 546 km with an inclination of 37 degrees.

In addition to its surveillance capabilities, the all-weather satellite with its SAR will send clear images for use in agriculture, forestry and disaster management support.

The contract for the nine commercial satellites was taken by Isro's newly formed commercial arm, NewSpace India Ltd, as the commercial agreement for 13 foreign satellites in the previous mission.

Earlier on May 22, Isro had successfully launched Risat-2B, the same version of the surveillance satellite, which replaced the old Risat-2 after completing its five-year lifespan. After the launch of Risat-2BR1 on December 11, the agency will launch Risat-2BR2 in the second half of this month. PSLV-C48 is the second PSLV flight in 'QL' configuration (with 4 belt motors). This will be the 75th mission of the SHAR launch vehicle and the 37th launch from the first launch pad.
