A portable three-dimensional position and velocity data archiving system for use with an aircraft during flight testing and evaluations. The system includes a ground based system and an airborne system. Each system includes a GPS receiver electrically connected with a GPS antenna for receiving and interpreting GPS signals transmitted from a GPS satellite constellation. Each system also includes a radio communication device for transferring position and velocity data as well as error correction data and guidance cues between the ground and airborne systems. The portable system acquires, processes, archives, and provides precise three-dimensional position and velocity data for the aircraft in real time. Information regarding aircraft position, direction, velocity, acceleration and any correction needs referenced to a selected coordinate system is immediately presented to a vehicle piloting crew on analog as well as digital indicators. |
