This project focuses on implementing Precise Point Positioning (PPP), Single Point Positioning (SPP), and Real-Time Kinematic (RTK) algorithms for postprocessing GNSS data. The main goal of this project is having a collection of high precision GNSS algorithms that are documented and implemented sustainably. The main implementation will be in C++ for best performance at a later point in this project.

  • Installation
  • CLI
  • Documentation

• Basic RINEX file reader in C++ and json export
• LSQ version of SPP and PPP alrogithms in MATLAB running. They will be translated and merged into the C++ main project later.
• Precise Ephemeris data (SP3) files parser (version d) and json export
• Precise Clock data (CLK) files parser (version 3.00 and later) and json export
• CLI Application to convert .obs, .nav, .clk and .sp3 to json format

Clone the repository:

git clone --recursive https://github.com/AndreasArendt/OpenRTK.git
cd OpenRTK

Usage of Command Line Interface CLI

	--dir <directory>  Parse Rinex data in directory, also sets output directory [--outdir]
	--obs <file> Parse Rinex obs data [.obs]
	--nav <file> Parse Rinex nav data [.nav]
	--clk <file> Parse Precise Clock data [.clk]
	--sp3 <file> Parse Precise Satellite Ephemerides data [.sp3]
	--export <type> Export File Type [c (combined); n (nav); o (obs)]
	--outdir <directory> Output data directory

Example: OpenRTK.exe --dir <Path> --export cno This exports the combined and navigation json file if .obs and .nav file exists in the given folder and their observation and navigation file seperately.
