RISAT-2BR1: ISRO eyes at Universe with its new launch


The Indian Space Research Organization (ISRO) scheduled to launch its latest radar imaging reconnaissance satellite ‘RISAT 2BR1’ on 22 May,2019 from Sriharikota, Andhra Pradesh. Its launch was earlier scheduled in 2020 after RISAT-2A but is now proponed.
The RISAT series by ISRO are first all-weather earth observation satellites. These Radar imaging satellites are designed to all-weather surveillance using synthetic aperture radars (SAR) i.e. they provide a continuous (24×7) view of earth day or night and even during bad weather for defence forces to detect infiltration along border. The series was primarily developed during the Mumbai terror attacks, 2008 as Indian forces were in dire need of round the clock surveillance. It was then RISAT-2, carrying Israeli built X-band radar was also launched.
Its main sensor is X-band synthetic aperture radars (SAR) which provided Indian defence forces all-weather surveillance for monitoring national borders to notice any potential threat or malicious activity and to carry out anti-infiltration and anti-terrorist operations.
About to be deployed RISAT-2BR1 satellite uses same SAR band and will further improve India’s imaging reconnaissance (surveillance) abilities.
The RISAT (radar imaging satellite), will be carried by PSLV-C46. It is one of the reusable variants of ISRO’s Polar Satellite Launch Vehicle (PSLV) rocket, which have offered significant progress and technology sophistication in terms of advancement in space technologies. The designation ‘C-46’ is as per ISRO’s numbering system.
