Expected operations in the coming month:

  • Week commencing 20th July: Attitude Determination & Control System (ADCS) Commissioning phase to obtain attitude data.
  • After three or four weeks: End ADCS Commissioning phase with a stable attitude.
  • In one month: Payload commissioning phase – solar panel and sail deployment which completes all major operations before deorbiting.

AMSAT and supporters are, again, so very welcome to help out by receiving the beacons so we can accelerate our commissioning. Further plans are available here:
