# **MAIN FUNCTION INTRODUCTION**
* Read the RINEX of Observation & Navigation of version 3.xx.
* The reading of RINEX of Observation & Navigation of version 4.xx will support in the KNZ_Calculate.[OINP]
* The reading of RINEX of Observation & Navigation of version 2.xx will turn into a convert software with GUI.[OINP]
* Calculate the coordinates of each epoch of the satellite in the ECEF coordinate system (.sp file).[ADIN 2024/10/5]
* With the help of KNZ_Plot, the coordinates of the receiver station can be calculated. And draw the image.[ADIN 2024/10/5]
* Until October 14, 2024, it is possible to calculate and output the satellite coordinates of the GPS & BeiDou & Galileo satellite system with KNZ_Calculate. With KNZ_Plot, pseudo-range single point positioning of GPS & Galileo satellite systems can be performed.[ADIN 2024/10/14]
Support version of RINEX:
* [RINEX of Observation of version 2.xx.](https://github.com/KenanZhu111/KNZ_Convert)(Support by KNZ_Convert)
* RINEX of Observation & Navigation of version 3.xx.
* RINEX of Observation of version 4.xx.
Support system of GNSS:
* GPS: Satellite position solving & Receiver station orientation
* Galileo : Satellite position solving & Receiver station orientation
* GLONASS : Satellite position solving
* BeiDou / Compass : Satellite position solving
# MAIN NOTICE
Support method of orientation
* Pseudorange positioning
* (OINP)
## Program notice
### About main calculate
* After a few updates, the observation file and navigation ephemeris file can be selected through the file dialog, and the SPP_calculate program can generate satellite position information (.sp file) in a folder specified by the user.
* The format of the (.sp file) is described in detail in the help documentation.
* Support the GNSS of GPS, BeiDou, Galileo.[ADIN 2024/10/14]
Features ：
* Realize 3D display of satellite orbit
# MAIN INTRO
## Program intro
### About KNZ_GeoTrackLab
* Added on October 24, 2024, merged from KNZ_Calculate and KNZ_Plot, improved operation logic, optimized interface display.
* Read more on help.doc
### About KNZ_Calculate(STOP)(Merge with KNZ_Plot )
* As of October 24, 2024, KNZ_Calculate has been merged with KNZ_Plot to form KNZ_GeoTrackLab.[ADIN 2024/10/26]
### About KNZ_Plot(STOP)(Merge with KNZ_Calculate )
* As of October 5, 2024, KNZ_Calculate has been merged with KNZ_Plot to form KNZ_GeoTrackLab.[ADIN 2024/10/26]
### About PyGMT(STOP)
* Until October 5, 2024, project for PyGMT drawing will no longer be considered.[ADIN 2024/10/5]
### About Matlab(STOP)(REPLACEED BY KNZ_Plot)
* Until October 5, 2024, project for Matlab calculating will no longer be considered.[ADIN 2024/10/5]
### About KNZ_Plot
* With the help of python's tkinter and matplotlib libraries, it is realized to read and process the.sp file generated by SPP_calculate and generate the (.po file) in the (.sp file) sibling directory. The generated.po file can be processed by KNZ_Plot to obtain line plots of ENU components.
* At present, the algorithm of station position calculation is integrated in the plot, and only two default tropospheric and ionospheric correction algorithms are supported at present, and the accuracy is still being optimized.
* Until October 14, 2024, with KNZ_Plot, pseudo-range single point positioning of the GPS & Galileo satellite system can be performed.[ADIN 2024/10/14]
* The format of the (.po file) is described in detail in the help documentation.
* As of October 5, 2024, PyGMT plot project will no longer be considered.[ADIN 2024/10/5]
### About Matlab(STOP)
* As of October 5, 2024, Matlab project will no longer be considered.[ADIN 2024/10/5]
## Project Update
### Big Update: 2024/10/26
1. Full gui
2. Integrated KNZ_Calculate and KNZ_Plot.
