The pandemic delayed the launch of the new-series geo-satellite, which has civilian and strategic significance, a number of occasions since final yr. Isro’s GSLV-F10 rocket will lastly put the two,268-kg Gisat-1, codenamed EOS-3, into the geo-orbit. This will probably be India’s first launch of a major satellite tv for pc this yr. On February 28, Isro had launched 18 small satellites, together with some desi satellites, together with major satellite tv for pc Amazonia-1 of Brazil.
As soon as positioned 36,000 km above earth within the geostationary orbit after house manoeuvres, the superior ‘eye within the sky’ can always monitor areas of curiosity (the satellite tv for pc will transfer in sync with the rotation of the Earth and therefore would look stationary) and can give real-time details about a big space in contrast to different distant sensing satellites positioned in decrease orbits that come to a spot solely at common intervals. EOS-3 will even allow fast monitoring of pure disasters, episodic and short-term occasions.
Minister of state for division of house Jitendra Singh, in a response to a query in Rajya Sabha just lately, had stated that EOS-03 is able to imaging the entire nation 4-5 occasions each day. The satellite tv for pc, which is able to close to real-time monitoring of floods and cyclones, will even allow monitoring of water our bodies, crops, vegetation circumstances and forest cowl adjustments, he stated.
The satellite tv for pc could have payload imaging sensors of six-band multispectral seen and close to infra-red with 42-metre decision, 158 bands hyper-spectral seen and close to infra-red with 318-metre decision and 256 bands hyper-spectral brief wave infra-red with 191-metre decision. A 4-metre diameter ogive-shaped payload fairing (warmth defend) has been used within the rocket for the primary time, an Isro assertion stated.
The satellite tv for pc was earlier scheduled for launch on March 28 this yr however a “minor problem” compelled its postponement. The launch was later anticipated in April after which in Could however Covid-triggered restrictions in states the place Isro centres are positioned delayed it once more.
After the Gisat-1 launch, the opposite satellite tv for pc to go up will probably be EOS-4 or Risat-1A, which is a radar imaging satellite tv for pc with artificial aperture radar (SAR) that may take footage throughout day and evening and may see via clouds. The satellite tv for pc weighing over 1,800 kg will probably be launched by a PSLV in September. The satellite tv for pc will play a strategic position within the nation’s defence with its functionality to function in day, evening and all climate circumstances.
The primary developmental flight of the Small Satellite tv for pc Launch Automobile (SSLV) or mini-PSLV can be scheduled for the fourth quarter of this yr from Sriharikota.
