Real-Time Kinematic Positioning Based on Un-differenced carrier Phase Data Processing

Y. Gao, K. Chen, X. Shen

Abstract:	This paper describes different processing models and numerical results of real-time kinematic positioning based on un-differenced code and carrier phase observations. Different from the conventional RTK methods, the position determination is based on the processing of code and carrier phase data from a single dual-frequency receiver corrected by precise GPS data to achieve position accuracy at the decimeter to centimeter level. The observation equations and data processing models are first presented in this paper and the numerical computation results are then described to assess the positioning performance with different data processing strategies. All data processing is conducted in real-time or real-time simulation and applies precise satellite orbit and clock corrections distributed over the Internet. The performance analysis focuses on the position convergence speed and accuracy.
