The Indian Space Research Organisation (ISRO) has released its annual report for 2019-20 recently.
- ISRO has been allocated with the budget of ₹13,480 crores for 2020-21.
- Currently, India has 19 national Earth Observation (EO) satellites, 18 communication satellites and 8 navigation satellites in service.
- These are used for broadcasting, telephony, Internet services, weather, agriculture-related forecasting, security, disaster-time rescue and relief and location-based services.
- Three of the communication satellites are dedicated to military communication and networking.
- The report states an annual plan of 36 missions (including both satellites and their launchers) including the launch of 10 Earth Observation (EO) satellites.
- The upcoming EO satellites include radar imaging satellites RISAT-2BR2, RISAT- 1A and 2A; Oceansat-3, GISAT-1 and Resourcesat-3/3S.
- ISRO plans to launch Chandrayan-3, Gaganyan in the year of 2020-21.
- ISRO also plans to launch a new series of high-resolution HRSATs through Polar Satellite Launch Vehicle (PSLV) launcher.
- ISRO is expected to develop its own space station within a decade.
- The RISAT-2BR2 will form a triad with RISAT-2B and RISAT-2B1 covering around 120 degrees apart.
- It will increase the frequency of observation in the required areas to provide all-weather, day/night imaging services from space.
- The RISAT satellites carry a synthetic aperture radar on them, providing all-weather, 24-hour information to security agencies.
- GISAT-1 (Geo Imaging Satellite) will be placed in a geostationary orbit of around 36,000 km.
- All Indian EOs satellites have been placed so far in a 600-odd-km orbits and circle the earth pole to pole.
- It will apparently be in a fixed spot looking over the Indian continent at all times.
- It will have high-resolution cameras which will help to monitor any changes in borders and the overall geographical condition of the country, etc.
