摘要
首先详细介绍了GPS相位平滑伪距差分定位的基本原理和数学模型,在此基础上编制了GPS相位平滑伪距差分定位软件,并结合实际算例对GPS相位平滑伪距差分定位进行了试验研究。结果表明:对于精度要求不是很高,但实时性要求较高的定位或导航来说,采用GPS相位平滑伪距差分定位是非常适宜的。
The basic theory and mathematical model of GPS phase smoothing pseudorange differential positioning is introduced in detail. On the basis of that, the software of GPS phase smoothing pseudorange differential positioning is compiled by the author of this paper, and experiment conducted in practice. The results demonstrate that the GPS phase smoothing pseudornage differential positioning technology is suitable for the positioning or navigational purpose, which requires lower accuracy but higher real-time.
