高精度北斗授时接收机授时方法分析和改进措施

Analysis and Improvement of Two Timing Methods in High-precision BDS Timing Receiver

北斗全球定位系统的建设使北斗应用技术得到了较快发展,基于高精度授时接收机的应用需求,对已知位置授时和自主定位授时2种方法进行了原理分析和精度比较,并基于自研高精度授时接收机进行了2种方法的对比测试。根据测试结果和实际应用场景,对授时设计技术优化和实现方法优化提出了建议,奠定了高精度应用和技术发展基础。

The construction of Beidou Global Positioning System has greatly facilitated the fast development of Beidou application technology.Based on the application requirements of high-precision timing receiver,the principles of two methods,i.e.known location timing and autonomous positioning timing,are analyzed,and their precisions are compared.Based on a self-developed high-precision timing receiver,a comparison test of the two methods is performed.According to the test results and the actual application scenarios,some suggestions are proposed for the optimization of the timing design technology and the implementation methods,laying the foundation for the development of high-precision timing application and technology.
