This report presents the results of a limited evaluation of a relative GPS datalink system installed onboard two USAF C-12C aircraft. This project was a risk reduction step to test the stability of the datalink to provide relative position and attitude information from a lead aircraft to a trail aircraft for the potential purpose of autonomous aerial refueling. Testing began on 11 Apr 05 and was completed on 2 May 05 after two two-ship formation flights. Relative position accuracy data between the two GPS receiver antennas were compared to GPS Aided Inertial Reference (GAINR) truth source data. The attitude data of the Micro-Electro-Mechanical System (MEMS) Inertial Measurement Unit (IMU) in the lead aircraft were also compared to the GAINR Embedded GPS/Inertial Navigation System (EGI).
