Ultra-low cost precision GPS
I am using this blog to document my work with RTKLIB and in the hope it may prove useful to anyone else trying to get started with this excellent open source program.
I describe the blog as “ultra-low cost precision GPS”. Several other blogs describe work on precision location with sub $100 GPS receivers but most if not all of these use relatively high quality antennas which can significantly increase the total cost.
The hardware I am using is available for $25 to $30 dollars total which includes both receiver and antenna. I believe this hardware requires some enhancements to RTKLIB to improve robustness, and that is what I focus on in these blog posts. As the blog has progressed I have expanded from just ultra-low cost to some slightly more expensive options including better receivers, antennas, and inclusion of radios.
There is a mix of information here, some of which is intended for those just getting started with RTKLIB and other posts that might be of interest for more advanced users. For those just getting started, I suggest clicking on “Getting Started” listed in the categories section part way down the right hand side on the main page. This will bring up all the posts I have geared towards a new user. Unfortunately the most recent posts appear at the top, so you will need to scroll to the bottom and work your way up.
I would be very interested in hearing about other similar work, so please leave a comment or send me an email at firstname.lastname@example.org if you are working in this area or if you have anything to add to any of the posts. My goal is also to document as completely as possible the work I have done, so if there is something I have skipped over that would be of interest to others, please let me know, and I will try to add a post.
All of the code changes and configuration files described in my posts are available in my Github repository. The most recent executables are available here and most of the data sets I reference in the blog are here.
