Microsat-R is an earth observing satellite manufactured by DRDO[1] and launched by Indian Space Research Organisation. Microsat-R is primarily an earth observation satellite and its payload was assembled by a handful of laboratories of the Defence Research and Development Organisation (DRDO) and is meant for military use. The satellite was “assembled outside and ISRO only interfaced it” with its own systems and the launch vehicle, just as it treats any customer satellite. ISRO has shied away from sharing details of the spacecraft or its uses as it does routinely each time during its missions; except to say the satellite would be placed within 15 minutes after take-off in a polar orbit 274 km away from Earth. This is much lower than any of its civil Earth observation spacecraft, which fly pole to pole over the globe at between 400 km and 700 km.[2] [3]

Launch[edit]

Microsat-R, along with KalamsatV2 as piggy-back, was launched on January 24th, 2019[4] at 23:37 hrs. The launch marks the 46th flight of PSLV. After 13 minutes 26 seconds in flight, Microsat-R was injected at an altitude of about 277.2km. This was the first flight of a new variant of PSLV called PSLV-DL with two strap-ons, each carrying 12.2-tonne of solid propellent [5]Also, this was the first time when fourth stage of launch vehicle was used as an orbital platform for micro-gravity experiments.
