In response to the ever increasing accuracies in inertial navigation systems, the U. S. Air Force must develop higher accuracy reference systems. These reference systems must also be small enough to be utilized in the testing of navigation systems onboard fighter aircraft. One such proposed system utilizes carrier-phase Global Positioning System CPGPS transmitters mounted on MM-9 pods with receivers on the ground. This research examines one possible method of utilizing this system to determine the attitude and position of the aircraft, given position estimates for the transmitters locations. The transmitter positioning algorithm showed that the geometry will be problematic for this configuration. However, if given the estimates of transmitter positions within the desired accuracy, the aircraft attitude and position algorithms worked effectively.
