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
