Optical Physics Company (OPC) has developed under SBIR Phase II funding an advanced laser pointing sensor system (LPSS) for future integration into the NASA Integrated Radio and Optical Communications (iROC) program. This would enable deep space pointing of high rate communications terminals to earth terminals via beaconless lasercom. The heart of the LPSS is OPC’s patented interferometric star tracker which can provide better than 300 nrad pointing accuracy. This paper will report on the LPSS technology and the upcoming ground field testing to verify the pointing accuracy required for deep space high rate laser communications.
