The next degree of accuracy for tillage, discing, mapping, spraying, spreading, harvesting, and field preparation is 3-4” or 8-10cm, and Topcon recommends TopNET Global D.
TopNET Global-D is designed to allow Topcon AGI-4 owners to quickly and easily subscribe to a consistent level of high-precision positioning to an accuracy of 5cm pass-to-pass, with no need for a base station or any hardware change in the current AGI-4 GNSS receiver.
