The INS 1B (ISRO NanoSatellite 1B) 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 1B carries two payloads:

  • the Earth Exosphere Lyman Alpha Analyser (EELA) designed by the Laboratory for Electro-Optics Systems (LEOS), Bengaluru. It registers terrestrial exospheric line-of-sight neutral atomic hydrogen Lyman Alpha flux and provides estimates for the interplanetary hydrogen Lyman Alpha background flux by means of deep space observations.
  • the Origami Camera payload from ISRO's Space Application Centre (SAC). It is a remote sensing colour camera with a novel lens assembly for optical realisation in a small package
