I am currently working with tractors using a RTK enhanced automated steering system. One of the biggest problems is that even RTK can have a inaccuracy of 2cm. This can be too much for some possible field applications like sowing. Therefore I am trying to determine the inaccuracy of such a steering system in dependence to the distance of the RTK-station. My problem right now is, that I don't have a way to measure the inaccuracy of the tractor driving the track.
In my current setup I want the tractor to drive 100m straight between two given points. Thereby I want to measure the inaccuracy. This I want to repeat with several distances to the RTK-station (1km, 2km, 3km, 4km, 5km, 10km, 15km, 20km, 30km, 40km). I hope that I can get a function which tells the inaccuracy in dependence to the distance of the RTK-station.
- Is there a way to process the points given by the GPS device to determine the inaccuracy?
- Do you know any visual validation method? (with stereo cameras or something)
- Do you have any other idea of how to measure the inaccuracy ?
