Precise kinematic GPS positioning

Tests in relative kinematic positioning usingTI 4100 GPS receivers on a land vehicle were carried out in September 1986 in the testnet “Werdenfelser Land” south of munich. Over the northern east-west traverse several stations with distances of 400 to 1000m were kinematically coordinated by use of dual-frequency code and carrier phase measurements. All cycle slips were removed by a specific algorithm based on Kalman filtering. Position agreements of centimeter-level were reached in a comparison of forward and backward run at six stations. The paper presents a description of the applied model and an analysis of the results.
