Accuracy

Whatever the challenge, we have a solution.

Accuracy and repeatability go hand in hand with Topcon GNSS precision.

As crop needs vary, TopCon provides accuracy options. Topcon precision solutions provide accuracies that range from entry-level, sub-meter to high-accuracy, sub-inch repeatable precision.




4-12" or 10-30cm
For tillage, discing, mapping, spraying, spreading, harvesting and field preparation, 4-12" OR 10-30CM accuracy is normally sufficient. Several GNSS correction methods can provide 4-12" or 10-30cm accuracy including DGPS, WAAS, EGNOS, MSAS, VBS, and L1 Only.




3-4" or 8-10cm
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.




1-12" or 2-30cm
CORS and NTRIP, with higher degrees of accuracy, are an appropriate choice for listing, bedding, planting, seeding, cultivating and ridging.




1-2" or 2-5cm
For strip tillage, landforming or land leveling, topographic mapping, listing, planting, bedding, ridging and cultivating, RTK Accuracy with Repeatability from Topcon delivers the best GNSS accuracy available.
