The In­dian Space Re­search Or­gan­i­sa­tion’s (Isro) work­horse, the Po­lar Satel­lite Launch Ve­hi­cle (PSLV) in its 44th flight put into or­bit two UK earth ob­ser­va­tion satel­lites, No­vaSAR and S1-4, in a text­book launch.

Both the satel­lites to­gether weighed about 889 kg, and the com­mer­cial launch was car­ried out un­der an ar­range­ment be­tween Sur­rey Satel­lite Tech­nolo­gies Lim­ited (SSTL) and Isro’s com­mer­cial arm An­trix Cor­po­ra­tion Lim­ited.

No­vaSAR is an S-Band Syn­thetic Aper­ture Radar (SAR) satel­lite in­tended for for­est map­ping, land use and ice cover mon­i­tor­ing, flood and dis­as­ter mon­i­tor­ing. It’s SAR pay­load has a ded­i­cated mar­itime mode de­signed with a very wide swath area (400-km) to en­able the mon­i­tor­ing of the ma­rine en­vi­ron­ment, and will pro­vide di­rect radar ship de­tec­tion in­for­ma­tion si­mul­ta­ne­ously with AIS ship track­ing data to as­sist with the iden­ti­fi­ca­tion and track­ing of sea-go­ing ves­sels.

S1-4 is a high res­o­lu­tion Op­ti­cal Earth Ob­ser­va­tion Satel­lite, used for sur­vey­ing re­sources, en­vi­ron­ment mon­i­tor­ing, ur­ban man­age­ment and for the dis­as­ter mon­i­tor­ing.

The PSLV-C42, was only the third launch of PSLV af­ter the fail­ure it en­coun­tered in Au­gust last year af­ter prob­lems in the heat shield. It took off took off at 10.08pm, the first stage sep­a­rated about two min­utes af­ter that, while the fourth state sep­a­rated nearly 17 min­utes af­ter the take off. The satel­lites sep­a­rated 17.44 min­utes af­ter the launch.
