NEW DELHI: Indian Space Research Organisation Isro ) is set to launch a new-age geo-imaging satellite Gisat-1 from Sriharikota on March 5 with the capability to perform real-time and constant watch of the Indian subcontinent.GSLV-F10 rocket will launch Gisat-1 from the second launchpad at 5.43 pm, subject to weather conditions.Weighing 2,275 kg, Gisat-1 is a state-of-the-art agile earth observation satellite that will be placed in a geosynchronous transfer orbit at 36,000km altitude. Operating from the geostationary orbit, Gisat-1 will facilitate near real-time observation of the Indian subcontinent, under cloud-free condition, at frequent intervals. Gisat-1 will apparently be in a fixed spot looking over the Indian continent at all times.“Gisat-1 will do a full rotation of the Earth and come to the same point after every 2 hours. It is really good for fast imaging of the Earth and can perform constant and rapid surveillance. If needed, the satellite can observe a point for a longer duration,” says a source in Isro. This will be the first satellite launch of this year from Indian soil.A 4-metre diameter Ogive-shaped payload fairing is being flown for the first time in this GSLV flight. This is the 14th flight of the GSLV.In all, Isro will launch an unprecedented 10 earth observation satellites with space surveillance feature during 2020-21 in order to boost the country’s space surveillance power in order to strengthen border security and check terrorist infiltration.
