The Indian Space Research Organisation (ISRO) launched the NovaSAR and S1-4 earth observation satellites of the U.K from the spaceport in Sriharikota.
The PSLV-C42 launch vehicle carrying the two satellites blasted off from the first launchpad at the Satish Dhawan Space Centre at 10.08 PM.
It was a perfect lift off, ISRO officials said.
NovaSAR is intended to be used for forest mapping, land use and ice cover monitoring, flood and disaster monitoring.
The S1-4 will be used for surveying resources, environment monitoring, urban management and disaster monitoring.
