Indian Space Research Organisation will add another feather to its hat when it will launch India’s most advanced and first state-of-the-art agile Earth Observation Satellite (EOS) just before Independence day on 12th August with the tentative take-off at 5.43 am.
It would be launched via the made in India Geosynchronous Satellite Launch Vehicle-F10 (GSLV-F10) from the Satish Dhawan Space Centre at Sriharikota in Andhra Pradesh.
Experts describe the advanced imaging satellite as a “game-changer” for India. The GISAT-1 with its high-resolution cameras will allow constant, real-time monitoring of the Indian landmass and the oceans. It can also be used in other key areas such as defence, enabling “special attention to the country’s borders for security reasons”.
ISRO said that the monitoring by the satellite will ensure precautions to be taken in advance at times of natural disasters and help reduce their impact. ISRO also said that apart from disaster warning, the satellite will also provide “spectral signatures for agriculture, forestry, mineralogy, cloud properties, snow and glaciers and oceanography” and will be carrying multispectral and hyperspectral cameras in different bands “with improved spatial and temporal resolution”.
However, the satellite needs cloud-free conditions to capture images. Union minister Jitendra Singh has told Rajya Sabha that the satellite can accomplish imaging of the whole country 4-5 times daily.
This is ISRO’s first primary satellite launch of this year. Earlier this year on February 28th, ISRO launched 18 small satellites including multiple Indian and a primary satellite Amazonia-1 of Brazil.
GISAT-1 would be placed 36,000 km above the earth in geostationary orbit in sync with the rotation of the earth, thus making it look stationary.
Its launch had been postponed multiple times due to multiple reasons including Covid. After this launch, ISRO will launch EOS-4 or RISAT-1A that is a radar imaging satellite with synthetic aperture radar (SAR) that can take pictures during day and night and can also see through clouds.
