ISRO successfully launches RISAT2B surveillance satellite into Low Earth Orbit
  • ​ISRO launches RISAT-2B surveillance satellite.
  • It will keep an eye on activities across LoC.
  • The satellite will also provide services to forestry and disaster management domains.

Indian Space Research Agency (ISRO) has successfully launched RISAT-2B (Radar Imaging Satellite-2B), a radar imaging earth observation satellite that can take high resolution images of the earth during day and night, and also under cloudy conditions with the help of a synthetic aperture radar. Apart from surveillance, the satellite intendeds to provide services to agriculture, forestry and disaster management domains. The PSLVC46, which carried RISAT-2B, lifted-off at 05:30am from Satish Dhawan Space Centre (SDSC), Sriharikota.


PSLV-C46 was the 72nd launch vehicle mission from SDSC SHAR, Sriharikota, ISRO said. About 15 minutes and 30 seconds after lift-off, RISAT-2B was injected into an orbit of 555 km at an inclination of 37 degree to the equator. “This is a very, very important mission for India. It is an excellent satellite with hi-fi earth observation (capabilities),” PTI (via The Economic Times) quoted ISRO Chairman K Sivan as saying.

The satellite will replace the RISAT-2, which was launched in 2009. India uses RISAT-2 to monitor terrorists activities at the borders adjacent to Pakistan and thwart their infiltration bids. The satellite also helped Indian intelligence agencies to plan surgical strike in 2016 in Pakistan-Occupied Kashmir (PoK) and the Balakot aerial strike earlier this year. The RISAT-2B has a lifespan of five years and will also be used for military surveillance.

ISRO is planning to launch a few more all-weather radar imaging RISAT satellites in the next one year. It is also preparing to launch Chandrayaan-2 in July which will land on Moon in September. The rocket carrying Chandrayaan-2 is expected to lift-off from SDSC. Chandrayaan-2 consists of three modules: the orbiter, lander (Vikram), and rover (Pragyan). The first two will be interfaced mechanically and stacked together as a single integrated module inside the launch rocket.
