A version of RTKLIB optimized for single frequency low cost GPS receivers, especially u-blox receivers. It is based on RTKLIB 2.4.3 and is kept reasonably closely synced to that branch. The latest branch of this code is demo5. Documentation for RTKLIB is available at rtklib.com. Binaries and tutorials for this code, and sample GPS data sets at :
