I am trying to setup an RTK base station to connect to a rover in a moving vehicle. The vehicle will always be with 2 miles of the base station. I’ve used really high dollar base stations in the past from specialist GPS companies but that isn’t necessary in this case.
When I’ve used base stations in the past to get the 1cm accuracy they need to be stationary and powered for 24hr and then they transmit corrections automatically. From a video I saw on the reference station it mentioned sending data to another source after that 24hr period to get the accurate corrections, is this correct?
Yes, but I think the best question is what are your accuracy goals (or requirements) for the project ?
If you only care about the relative precision in terms of the local project scope (2 mile radius), that would be a simple task (survey-in).
If you need to validate the accuracy of the car’s position in a meaningful manner, or require a minimum absolute accuracy, then establishing firm coordinates for the Base is generally required (OPUS, PPP, etc).
You also have other options as well if your car (or nearby ground station) has access to the internet to receive RTK corrections without you running a local Base.
Or you can use a L-Band enabled Rover to receive those corrections from a satellite.
There are many ways to skin this cat, and lots of people here that can help
