Carrier Phase GPS Time, Space, Position Information Demonstration (CAPTIDE)

Gregg Costable

Abstract:	This paper presents a discussion and results of a flight test to obtain Time, Space, Position Information (TSPI) using carrier phase (or kinematic) GPS. A carrier phase capable GPS receiver was installed on board an F-16 aircraft and flown in conjunction with an INS/differential GPS guided weapon test program. The carrier phase TSPI data was compared to the position solution from existing test range TSPI sources, including: four high- dynamic Contraves cinetheodilites operated at 30 frames per second, two FPS-16 radars, the aircraft position system solutionan INS/GPS position measurement pod on board the aircraft, and a post-mission Kalman smoother based software algorithm called “test data optimal processor”. The carrier phase and test range solutions were also compared to the INS/DGPS test items. A series of aircraft manuevers were conducted to collect truth data to compare the carrier phase GPS position with the “truth” position. This was the first experiment known to the authors which utilized the carrier phase observable in an aircraft environment where high accuracy TSPI was available to evaluate the accuracy of the carrier phase technology.
