摘要

本文主要研究无线电波传播条件对局部定位系统无线电信号参数的影响。考虑了天线高度对无线电频率的选择以及无线电导航参数计算的精度。考虑了直线传播、大气折射传播和双通道传播三种情况，估计了时延精度的退化。讨论了在困难传播条件下运行的局部定位系统中首选的调制方法。对行星局部定位系统的自动部署提出了建议。

Radio wave propagation impact on signal parameters of local positioning systems

This article focuses on radio wave propagation condition impact on local positioning system radio signal parameters. The choice of radio frequency depending on antenna heights is considered as well as the accuracy of radio navigational parameter calculation. Time delay accuracy degradation is estimated considering the cases of rectilinear propagation, atmospheric refraction propagation and two-ray channel propagation. Modulation methods preferred for usage in local positioning systems operating in difficult propagation conditions are discussed. Recommendations for automatic deployment of planetary local positioning system are made.
