Microsat-TD was an Earth observing satellite developed by ISRO.2 Its launch marked India's 100 satellites in space.3 This satellite could capture images at night by imaging in infrared spectrum.45

Launch

MICROSAT-TD satellite was launched at 0359 UTC on 12 January 20186 by PSLV-C40 and its deployment profile was previously rehearsed on PSLV-C38 mission.78 Microsat-TD was launched along with Cartosat-2F, INS-1C and 28 satellites from 6 countries9 and separated 1 hour 45 minutes after first stage ignition.10 Duration of PSLV C40 mission was 2 hours and 21 minutes, making it the longest mission of PSLV at that time.

Payload

Microsat-TD was IMS-1 based technology demonstrator carrying optical imaging payload in two bands.1112

  • 0.8 meter resolution (panchromatic, 0.5 -0.85 μm) with 3.2 km swath
  • 6 meter resolution (IR, 3.7-4.8 μm and 8-12 μm) with 2 km swath

End of mission

To reduce its orbital stay, Microsat-TD was de-orbited while depleting its left over propellant near the end of its life. Satellite reentered within a month, on 27 November 2020.1
