| Abstract: | According to the requirement of high-precision satellite navigation,the method and result of quasi-real-time monitoring the variation of the regional ionospheric TEC(total electron content) and GPS satellite differential code bias(DCB) are introduced.The pseudo-range data smoothed by dual-frequency carrier phase are used from the GPS networks in China.Especially,the feasibility of retrieving DCB independently from the regional GPS networks with different sizes is studied.Three networks based on the GPS stat... |
