The Indian space agency ISRO is carrying out pre-rocket launch activities at its rocket port in Andhra Pradesh's Sriharikota for sending up its earth observation satellite EOS-03 or Geo Imaging Satellite-1 (GISAT-1) early on Thursday, officials said.
While its officials are keeping a studied silence on the launch, it has been learnt that the rocket - Geosynchronous Satellite Launch Vehicle-F10 (GSLV-F10), loaded with GISAT-1, is at the second launch pad, and is expected to blast off at 5.43 a.m.
The GISAT-1 will be the country's first sky eye or earth observation satellite to be placed in geo-stationary orbit.
The 51.70 metre tall and 416 ton GSLV-F10 will, just over 18 minutes into its flight, place GISAT-1 at the geosynchronous transfer orbit (GTO) from where the satellite will be taken up to its final position firing its onboard motors.
Once placed in geostationary orbit, the satellite will have a steady eye on the areas of interest - moving in sync with the rotation of the earth and hence seeming stationary - unlike other remote sensing satellites placed in lower orbit that can come over a spot only at regular intervals.
Originally the GISAT-1 was slated for launch on March 5, 2020, but hours before the launch, the ISRO announced postponement of the mission owing to some technical glitch.
