摘要
随着卫星导航系统的飞速发展,卫星导航定位技术正朝着实时、高精度和高可靠性的方向发展。在实现实时PPP和多系统网络RTK等技术中,高效准确地实时解码原始数据能够为后续的数据分析和处理提供可靠的保障。本文系统地介绍了u-blox M8接收机原始数据流的内容和格式,分析每种数据格式中的信息组织结构,给出了相关电文解析方法,实现了多系统原始GNSS数据流的实时解析。作为应用实例,基于解码后的数据分别进行了伪距单点定位和差分定位等,进一步证明了解码后数据的有效性和正确性。
With the rapid development of satellite navigation system, satellite navigation and positioning technology is moving in the direction of real-time, high precision and high reliability. In the realization of real-time PPP and multi-system network RTK technology, efficient and accurate real-time decoding the original data can provide the reliable guarantee for follow-up data analysis and processing. This paper introduces the content and format of GNSS raw data stream about u-blox M8 receiver, analyzes the information organization structure of each data format, and gives the relevant message analysis method to achieve the real-time analysis of the original GNSS data stream of the multi-system. As an application example, the pseudo-range single-point positioning and the differential positioning are respectively performed based on the decoded data, and the decoded data is further proved to be correct and effective.
