# **MAIN FUNCTION INTRODUCTION**
|
|
|
|
* Reads the specified observation data and navigation data.
|
|
* Calculate and document the longitude and latitude coordinates and height of the satellite at each epoch time.
|
|
* With the help of PyGMT, the output document information is processed and the satellite ground track map is drawn.
|
|
* With the help of MatLab tool, the satellite position is calculated and the station position is obtained by simultaneous solution,
|
|
and the precision is evaluated by comparing with the coordinates of the precise station.
|

# MAIN NOTICE

|
## Program notice
|
|
### About main calculate
|
|
* Due to the lack of program writing experience,
|
|
the ease of file reading is not perfect,
|
|
if you need to read other observation files and navigation files,
|
|
you can make changes in the ***main.c*** file.
|
|
### About PyGMT
|
|
* I have improved the drawing part of PyGMT
|
|
to ensure that the output data can be used independently.
|
|
### About Matlab
|
|
* When the new station data is needed for calculation,
|
|
two parts of parameters in the Matlab source file need to be corrected,
|
|
the first is the exact coordinates of the station in the file header,
|
|
and the second is the longitude, latitude and elevation information of the station in the file header
|
|
|
|
## Project notice
|
|
* Due to my limited programming level, PyGMT drawing used too miscellaneous judgment statements,
|
|
resulting in slow drawing or debugging errors, please forgive me.
|
|
* When writing the code, with the help of the existing open source code results,
|
|
and different degrees of reference, here one by one mark and express thanks:
