A version of RTKLIB optimized for low cost GNSS receivers (single, dual, or triple frequency), especially u-blox receivers.  It is based on RTKLIB 2.4.3 and is kept reasonably closely synced to that branch.   This software is provided “AS IS” without any warranties of any kind so please be careful, especially if using it in any kind of real-time application. 

Releases with Windows executables are avaiable at https://github.com/rtklibexplorer/RTKLIB/releases 

Tutorials for this code, and sample GPS data sets are available at http://rtkexplorer.com/  

The latest version of the user manual is at: https://rtkexplorer.com/pdfs/manual_demo5.pdf
