Isro to launch satellites to combat the ageing fleet

The country’s space agency chairman told ET about the end of life of satellite in orbit. It has led to a decision to replacement of more than ten satellites. They are planning to launch satellites with high-speed internet more than 300 gigabytes per second.

The first satellite that is GSAT-30 is going to replace INSAT 4-A. It is a 15-year old satellite. The launch happened on 17 January, which Carries 12C and 12 Ku band transponders for communication and transmission, respectively.

ISRO Chairman K Sivan commented that there is an urgent requirement of advanced satellites in the field of communication, navigation and earth observation. ISRO’s communication satellite is 36000 km above the earth, which moves in a geostationary orbit. The lifespan of the moon is 12-15 years. Thus, the new satellites will be more powerful and advanced features. Recently, the total number of satellites is 17.

The primary reason behind these replacements includes the profound change in technology in the 15 years. Since our satellites have completed 15 years and hence they are not up-to-date and not suitable for the new requirements.
The Communication requirements need more transponders and hence creating its high demand. The transponders got hired from foreign satellites. However, ISRO is still lacking in reaching the target of 500 transponders to work with the new requirements.

It has led to a decision to launch ten satellites to replace its aging fleet and to work better in the areas of communication and navigation.
