I have a permanent base station as well as rovers based off the f9p chip that I would like to configure to use the NAD83 datum instead of the WGS84 datum so that my lines and field stay relatively consistent year after year. Does anyone know if this is configuration is possible with these chips? If it is possible, could someone please show me where in u-center I would make these changes?
Generally speaking the datum doesn’t matter. Your base station’s latitude and longitude isn’t changing (unless you re surveyed it), so your rover lines won’t move from year to year. Even as the continents drift. That’s the whole point of RTK with your own base station. Relative accuracy is always maintained.
If you’re going to share your data and lines with others then datum matters. To set the datum to nad83 you’ll need to do 24 hours of observations and then send them to a government PPP service that will give you the latitude and longitude in the local datum.
