Isro To Launch GISAT-1 In Less Than 24 Hours, A Game-Changer For India: Points To Know

The countdown for the launch of India's "eye in the sky," the GISAT-1 Earth observation satellite, began on Wednesday morning, according to the Indian Space Research Organisation (Isro) (EOS). The satellite will be launched from the Satish Dhawan Space Centre (SDSC) in Sriharikota, Andhra Pradesh, on a geosynchronous satellite launch vehicle (GSLV) as part of the GSLV-F10 EOS-03 mission at 5:43 a.m. on Thursday. India is looking forward to the much-anticipated event, which has been planned just days before the country's achievements are celebrated on Independence Day.

Because of its usefulness in Geosynchronous Transfer Orbit before moving on to the final geostationary orbit, the GISAT-1 satellite launch has been dubbed a game-changer in terms of India's space goals. Here's a quick rundown of the satellite launch's scope.

1. The Geo Imaging Satellite-1 (GISAT-1) is an Isro-launched satellite that will keep a watch on "locations of interest" for India. It will essentially function as India's "eye in the sky."

2. In response to a question in Parliament earlier this week, Jitendra Singh, the Union minister of state in charge of the department of space, stated that the Earth observation satellite will give Isro 4-5 photos from around the country every day.

3. According to officials acquainted with the situation, India would be able to monitor and respond to natural disasters and other short-term occurrences at an alarming rate using these images.

4. Furthermore, the GISAT-1 satellite will collect spectral fingerprints for agriculture, forestry, mineralogy, cloud characteristics, snow and glaciers, and oceanography, allowing academics at home to learn more about a variety of topics.

5. According to Isro, the launch vehicle will deploy the Earth observation satellite in a highly elliptic geocentric orbit known as the Geosynchronous transfer orbit, which is nearly often used as an intermediary stage for satellites before reaching their final orbit. The geostationary altitude is 42,164 kilometres (26,199 miles) above sea level, which corresponds to the apogee of the GTO Earth orbit.

6. Once in orbit, EOS-03 will appear immobile in space since it will rotate at the same rate as the planet. This is significant because, unlike low-Earth satellites, the geostationary satellite will not have to constantly alter its position, allowing India to monitor key areas of interest around the clock in real-time.

7. The 2,268-kg state-of-the-art agile satellite GISAT-1 will be launched into geosynchronous orbit by Isro's GSLV-F10 rocket. This spacecraft, called EOS-3, will be launched on the GSLV's fourteenth flight.

8. The fairing capsule used in Isro's satellite has been modified. This time, the space agency announced that it will deliver an Ogive-shaped payload with a diameter of 4 metres, which is a first.

9. The launch of GISAT-1 was scheduled for March 5 last year, however, it was postponed because of the coronavirus illness (Covid-19) pandemic and accompanying technical difficulties. It was subsequently rescheduled twice more, initially for March 28 and then again in May due to the pandemic's second wave, before finally being set for August 11.

10. The filling of the oxidiser for the second stage (GS2) of the GSLV-F10 has been finished, according to the space agency's latest update, while the loading of propellant for the second stage has begun.
