RISAT-2B, useful in agriculture, forestry, disaster management, successfully launched

The previous RISAT-2 satellite, fast-tracked in the aftermath of the 2008 Mumbai attacks, is used for border surveillance, to deter insurgent infiltration and for anti-terrorist operations


Sriharikota: India’s Polar Satellite Launch Vehicle (PSLV-C46) today successfully launched RISAT-2B satellite from Satish Dhawan Space Centre(SDSC) SHAR, Sriharikota. This was the 72nd launch vehicle mission from SDSC SHAR, Sriharikota and 36th launch from the First Launchpad.

PSLV-C46 lifted-off at 5:30 AM (IST) from the First Launchpad and injected RISAT-2B into an orbit of 556 km, about 15 minutes and 25 seconds after lift-off.

PSLV-C46 successfully injects RISAT-2B into low earth orbit.

After separation, solar arrays of RISAT-2B were deployed automatically and ISRO Telemetry Tracking and Command Network (ISTRAC) at Bengaluru assumed control of the satellite. In the coming days, the satellite will be brought to its final operational configuration.

RISAT-2B is a radar imaging earth observation satellite weighing about 615 kg. The satellite is intended to provide services in the field of agriculture, forestry and disaster management.

ISRO Chairman Dr K Sivan congratulated the launch vehicle and satellite teams involved in the mission. “With this launch, PSLV lofts 50 tonnes to space by launching 354 satellites, including national, student and foreign satellites.”

K Sivan also commended the efforts of the team involved in the realization of the piggyback payload carried onboard this mission namely, Vikram processor and low-cost, MEMS-based Inertial Navigation System (INS) developed by Semi-Conductor Laboratory (SCL), Chandigarh and ISRO Inertial Systems Unit, Thiruvananthapuram respectively. He also quoted “RISAT-2B is an advanced earth observation satellite with the advanced technology of 3.6m radial rib antenna”

A total number of 5,000 visitors witnessed the launch live from the Viewer’s Gallery, which is opened to the public.

ISRO is now gearing up for the launch of Chandrayaan 2 onboard GSLV MkIII during the window of 9 July to 16 July, with an expected moon landing on 6 September 2019.

RISAT evolution

While RISAT-1 is an indigenously developed radar-imaging satellite successfully launched by a PSLV-XL rocket on 26 April 2012 from Satish Dhawan Space Centre, Sriharikota, it was postponed in order to prioritise the building and launch of RISAT-2.

RISAT-2 was the first of the RISAT series to reach orbit. It was launched successfully on 20 April 2009 at 0015 hours GMT by a PSLV rocket. The 300-kg satellite was built using an X-band SAR manufactured by IAI.

This satellite was fast-tracked in the aftermath of the 2008 Mumbai attacks. The satellite is used for border surveillance, to deter insurgent infiltration and for anti-terrorist operations. It is likely to be placed under the Aerospace Command of the Indian Air Force.
