ISRO Develops Tech to Boost Satellite Life by 5 Years

India's space scientists have developed electric propulsion technology that is expected to boost the life of geostationary satellites by upto five years.

The system - plasma thrusters - would be tested in GSAT-4 spacecraft slated to be launched on board GSLV later this year .

So far, ISRO had been using chemical propulsion for station-keeping, altitude control, precision spacecraft control, stabilisation and orientation.
