载波平滑码(CSC)算法是一种有效的伪距多径抑制技术,可以减轻GPS观测数据传输的计算负担,降低通信带宽。本文提出了一种改进的Hatch滤波器,并基于最优参数估计理论研究了双频GPS数据的最优CSC算法。平滑的观测结果具有与原始双频GPS数据相同的信息内容。因此,最优CSC算法等价于非组合算法。理论分析表明,最优CSC算法的数据精度优于哈奇滤波及其改进版本。
Carrier-smoothed-code (CSC) algorithm is an effective pseudorange multipath mitigation technique, which can alleviate the computational burden and reduce the communication bandwidth needed for the transmission of GPS observations. This paper presents an improved Hatch filter and addresses the optimal CSC algorithm for dual-frequency GPS data based on the optimal parameter estimation theory. The smoothed observations have the same information content as that of the raw dual-frequency GPS data from which these are derived. Consequently, the optimal CSC algorithm is equivalent to the uncombined algorithm. Theoretical analyses show that the data precision of the optimal CSC algorithm is better than that of Hatch filter and its improved version.
