Embodiment

[0061] The present invention is a Beidou real-time precise orbit determination method based on satellite perturbation, and the specific steps include:

[0062] Step 1, the satellite observation information is collected and the user sends a positioning request signal

[0063] The satellite observation information and navigation information of the Beidou Navigation System are collected by the ground observation stations distributed evenly around the world, and the information collection results of each station are sent to the data processing center through the Internet communication link, so that the data processing center can easily access and backup.

[0064] Step 2, the construction of satellite observation equation

[0065] The data processing center preprocesses the satellite navigation information and observation information, including the elimination of outliers in broadcast ephemeris and smoothing of pseudoranges.

[0066] In the process of abnormal broadcast ephemeris ...
