Satellite INSAT-3E falls out of commission
Communications satellite INSAT-3E has finally been decommissioned by the ISRO days after it started to dwindle away to defunctness. The 3rd generation satellite, supposed to function for 15 years, could only last ten-and-a-half years. ISRO has already begun to migrate its users to other satellites.
Points to know
- It was the 4th satellite (chronologically) launched in the INSAT-3 series of ISRO in September 2003.
- It was developed to provide high-speed communication, Television, VSAT & Tele-education services.
- It was studded with 36 transponders — 24 C-band and 12 extended C-band transponders.
- It ran into trouble in 2009 which crippled its capacity to just 25 working transponders.
- The immediate reason was the unavailability of on-board oxidiser which had supposedly been used up.
- Oxidiser along with fuel are mandatory to keep the satellites stationed over India (any given place).
- They also come handy in the day to day operations.
- It is likely to be replaced with soon to be launched GSAT-16.
- Now its going to be pushed into a higher orbit so as to safeguard other working spacecraft -transiting the space- from collision or damage.
INSAT (Indian National Satellite System)
- A series of geo-stationary satellites launched by ISRO to serve the nation in the area of telecommunications, broadcasting, meteorology, and search and rescue operations.
- INSAT, the largest domestic communication system in the Asia Pacific Region, has so far launched 21 satellites into space.
- Eleven of them are still in operation.
