SCIENCE AND TECHNOLOGY : ISRO launches two satellites NovaSAR and S1-4 using PSLV-C42


 

·         Indian Space Research Organisation (ISRO) successfully launched two satellites— NovaSAR and S1-4-belonging to United Kingdom (UK).

·         Both satellites were injected into Sun Synchronous Orbit (pole-to-pole orbit) at an altitude of 583 km after the launch.

·         These satellites were launched on board of Polar Satellite Launch Vehicle (PSLV-C42).

·         This was the 44th flight of PSLV and the 12th flight of Core Alone version of the vehicle.

·         Core Alone version of PSLV is lightest version without six strap-on motors. It is used for smaller payloads.

·         It was ISRO’s first fully commercial trip of the year.

·         S1-4 Satellite is high resolution earth observation satellite meant for surveying resources, environment monitoring, urban management and disaster monitoring.

·         NovaSAR Sateillite carries S-band Synthetic Aperture Radar (SAR) and Automatic Identification Receiver payloads. It is technology demonstration mission designed to test capabilities of new low cost S-band SAR platform. Its applications include forestry mapping, land use and ice cover monitoring, flood and disaster monitoring and maritime missions.

·         It is capable of launching 1600 kg satellites in 620 km sun-synchronous polar orbit and 1050 ks satellite in geo-synchronous transfer orbit.

·         There are three variants of PSLV, namely, PSLV-G, PSLV-CA, PSLV-XL.

·         In the standard configuration, it measures 44.4 m tall, with a lift off weigh of 295 tonnes.
