What to study?

For Prelims and Mains: Key features and significance of the mission.

 

Context: India’s Polar Satellite Launch Vehicle (PSLV), in its 47th mission (PSLV-C45), will launch EMISAT, the primary satellite and 28 international customer satellites from Satish Dhawan Space Centre (SDSC) SHAR, Sriharikota.

This mission will be ISRO’s first attempt at placing payloads in three different orbits.

 

EMISAT mission and its significance:

  • EMISAT is meant for electromagnetic spectrum measurements. It will be released into an orbit at 749 km.
  • EMISAT is primarily based on the famous Israeli spy satellite called SARAL or (Satellite with ARgos and ALtika), and inherits its SSB-2 bus protocol for conducting sharp electronic surveillance across the length and breadth of India.
  • The satellite would serve as the country’s roving device for detecting and gathering electronic intelligence from enemy radars across the borders as it circles the globe roughly pole to pole every 90 minutes or so.

 

Foreign satellites on-board:

  • As many as 28 small foreign co-passenger satellites will also travel to space with it, but to a lower orbit at 504 km.
  • They include 24 small satellites from the U.S., the other four customers are from Lithuania, Spain and Switzerland.
