Mission Objectives:
  • Primary: Evaluate propagation of RF signals through the atmosphere
  • Secondary: Assess 3U cubesat performance; evaluate potential for sub-100m orbit prediction capability without on-board GNSS

Role of Satellite Laser Ranging:

  • Potential source for continued evaluation of BK7 corner cube retroreflector performance in space environment
  • Assess orbit determination for 3U cubesats below 600km altitude
  • Enable smallsat RF links through increased orbit prediction accuracy
