HiakaSat (HawaiiSat 1)

HiakaSat [University of Hawaii]

HiakaSat (Hyperspectral Imaging, Aeronautical Kinematic Analysis Satellite), also known as HawaiiSat 1, is a microsat mission developed by students of the University of Hawaii, Honolulu (Ma-noa).

The mission has following goals:

  • Demonstrate a cost effective on-orbit platform for performing technology demonstrations
  • Perform remote sensing with the newly designed space ultra-compact hyper-spectral imager (SUCHI)
  • Perform imaging with two HSFL color cameras which are co-aligned with SUCHI
  • Provide workforce development opportunities for students and recent graduates
  • Further develop infrastructure for sustainable satellite development, integration and test, and operations

Originally the HawaiiSat 1 mission was to be built on a larger bus and was to feature the THI (Thermal Hyperspectral Imager) payload. It was to weight 80 kg. Later during development, the available mass was cut to 40 kg, later raised again to 55 kg. Therefore the HawaiiSat 1 structure was cut in half and the THI payload was replaced by the light weight SUCHI. This redesigned satellite was renamed HiakaSat.

HiakaSat was launched as the prime payload of the ORS-4 mission in November 2015 on the new low-cost Super-Strypi launch vehicle from Kauai, but was lost in a launch failure.
