5. Bring out the latest advanced made by ISRO in satellite technology.

इसरो द्वारा उपग्रह प्रौद्योगिकी में किए गए नवीनतम उन्नत को सामने लाएं।।


Indian Space Research Organization (ISRO) was established in 1969. Since its beginning, ISRO has created a niche for itself in the space technology world through continuous low-cost innovations.


Latest advancements by ISRO in satellite technology:

  • GSLV Mark III – developed by ISRO with its own cryogenic engine. The launch vehicle is capable of carrying 4 ton satellites into the geosynchronous transfer orbits.
  • GSAT-7A- Indian Communication satellite built to provide communication capability to the users over the Indian region.
  • GSAT-11- India’s heaviest and most-advanced high throughput communication satellite. It will boost the broadband connectivity to rural and inaccessible Gram Panchayats in the country coming under the Bharat Net Project
  • HysIS- Hyper-Spectral Imaging Satellite (HysIS) is an earth observation satellite built to study the earth’s surface in both the visible, near infrared and shortwave infrared regions of the electromagnetic spectrum. Data from the satellite will be used for a wide range of applications including agriculture, forestry, soil/geological environments, coastal zones and inland waters, etc.
  • Vikas engine- The semi-cryogenic Vikas engine will improve the payload capabilities of PSLV, GSLV and GSLV Mk-III launch vehicles.
  • Small Satellite Launch Vehicle (SSLV)- It will be exclusively for small satellites such as nanosats and cubesats and will offer affordable launch options in India and help boost revenues 
  • IRNSS – ISRO helped launch India’s own GPS system consisting of 7 satellites. It is capable of navigating the entire Indian subcontinent
  • Reusable Launch Vehicle– demonstrated successfully. This would help reduce the cost of future launches to a fraction of present ones
  • Launch of 100+ satellites in single launch in 2017 – the PSLV created a world record by simultaneously launching 104 satellites with 101 coming from foreign countries
  • Mangalyaan- The Mars Orbiter Mission is a space probe to explore and observe Mars surface features, morphology, mineralogy and the Martian atmosphere.


The success of ISRO is testament to India’s capability in frugal engineering and finding solutions with severe resource constraints and international non-cooperation. Future missions like Chandrayaan-2, Aditya-L1, Gaganyaan etc. will help India enhance its global image even further.
