In a pre dawn launch, Indian Space Research Organisation (ISRO) scripted history on Wednesday by successfully launching its radar imaging satellite RISAT-2B on May 22, 2019.Agency’s trusted workhorse Polar Satellite Launch Vehicle (PSLV-C46) blasted off at 5.30 am from the first launch pad of the Satish Dhawan Space Centre in Andhra Pradesh’s Sriharikota on its 48th mission, carrying the 615 kg satellite.
It was released into the orbit around 15 minutes after the lift-off.It is a radar imaging earth observation satellite.RISAT 2B was launched into a 37° inclination to the equator and orbit at 555 km orbital height.
With a mission life of five years,the RISAT-2B (Radar Imaging Satellite-2B) with its X-band radar will provede services in fields such as surveillance, agriculture, forestry and disaster management support that would enhance the country’s surveillance capabilities among others.It will be vital to the armed forces also as the radar imaging satellite can penetrate through thick cloud cover and identify hidden objects on the ground.
ISRO Chairman K Sivan said that this was a very important mission for India as this excellent satellite with hi-fi earth has very good observation capabilities.
The RISAT-2B can take pictures of the earth and observe weather conditions using radar imagery of any weather conditions during day time or night time as it is equipped with synthetic aperture radar.
A radar imaging satellite is complex to assemble. Interpreting its images is equally complex.
It will mark the recommencement of a vital ring of Indian all-seeing radar imaging satellites after seven years.
It will add to the reconnaissance capability from about 500 km in space. A constellation of such space-based radars means a comprehensive vigil over the country.
It would replace the RISAT-2, which was successfully launched in 2009.
