INS 1A

INS 1A [ISRO]

The INS 1A (ISRO NanoSatellite 1A) is a nanosatellites developed by ISRO.

Each of the INS 1 satellites has a weight of 10 kg including a payload mass of 5 kg. The mission life is expected to be six months to one year. These missions serve to evaluate the INS bus as a versatile and modular Nano satellite bus system envisioned for future science and experimental payloads.

INS 1A carries two payloads, both developed by ISRO's Space Application Centre (SAC):

  • the Surface BRDF Radiometer (SBR) payload to measure the Bidirectional Reflectance Distribution Function (BRDF) of targets on the earth's surface and will take readings of the reflectance of different surface features.
  • the Single Event Upset Monitor (SEUM) to monitor Single Event Upsets occuring due to high energy radiation in space environment in COTS (Commercial Off-The-Shelf) electronic components.
