Hi, Need some advice on your products. Need a small board that can offer 1cm GNSS accuracy with relevant aerial. The output needs to go to a system that will be able to convert the data to a display on a map of my choosing. I am trying to learn as best I can about this tech. Looking for a very simple system. The location tracking needs to be implemented outdoors and is NOT speed dependent.
The ~1cm GNSS is the easy part of your request with the SparkFun RTK lineup, under controlled conditions.
The “map of your choosing” is pretty open-ended.
If you need to create an aerial with 1cm ground accuracy, then you’ll want to research OrthoMosaics and GeoRectification (software products like Pix4D).
How much of this will you be responsible for coding?
RTK can get you to a few cm in ideal condition, and you providing access to local infrastructure, ie either you own base station equipment and radios, or WiFi / Cellular connectivity to internet data services / NTRIP providers.
Small board, probably looks at some thing in the 3x3" or 4x4" realm to stand some chance.
