####################################################################################
Overview: This is the demo5 version of the RTKLIB code customized for improved performance with low-cost single frequency and dual frequency receivers. It was last updated on 11/9/2021 and is synced up to the b34 versions of the 2.4.3 branch of RTKLIB. 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. The source code is available here. The zip files below include Windows versions of the executables as well as sample command files (*.cmd) and RTKLIB config files (*.conf) for the u-blox M8T and F9P receivers.
Note about virus scanners: Most popular virus scanners do not have any issues with these zip files, including McAfee, MicroTrend, AVG, and Avast. However, a few others have recently started flagging some of the files as suspicious for reasons I don't quite understand, although I am fairly certain they do not contain a virus. If you get a warning from your virus scanner I suggest you submit the file to VirusTotal which will scan it with 60+ different virus scanners and give the results for all of them. I generally see 55+ of the 60+ scanners do not find any viruses in this download. Starting with b33c, I have removed the 32 bit apps that used to have both a 32 bit and 64 bit versions from the download package since they seem to contribute more to the virus warnings. If needed, these can still be built from the source code in the Github repository.
Optional Contribution: No pressure... I do this because I enjoy it, not to pay the bills. However, if you are a regular user of the demo5 code, find value in the software, and would like to share that value, then any contribution is much appreciated. Use the comment field to add any feature or bug fix that you would like to see added to the demo5 code.

I have made some fairly significant changes to the code in the last couple of releases. It is difficult for me to test every configuration of RTKLIB so it is quite possible I have broken some features that previously worked. I rely on the users to help me find these issues and fix them. If you find a feature or configuration that worked in one of the previous versions of the demo5 code but does not work in the latest version, please let me know with as many details as possible about the exact configuration and which version in which it last worked .
