SIGMA (Scientific cubesat with Instruments for Global magnetic field and rAdiation) or KHUSAT 3 (Kyung Hee University Satellite) is a 3U cubesat developed at the Kyung Hee University, South Korea.

The mission of SIGMA is to measure global magnetic field and radiation.

The payloads on board are:

  • TEPC - Radiation Detector
  • Magnetometer on a deployable boom

The satellite was to be launched as a secondary payload on a Falcon-9 v1.2 rocket, but was later moved to a PSLV-XL rocket. It wass expected to operate for three months.

Launch and deployment was successful, but apparently no contact with SIGMA was established after deployment.
