About this app

ColDonAgro is a tractor GPS guidance app for parallel driving in the field. A free farm navigation lightbar with GPS/GNSS, RTK support, sprayer section control, yield mapping and autosteer.

ACCURACY
The app shows your position from the receiver it is connected to. The phone's built-in GPS gives 2–5 m accuracy — enough to try the app and measure a field. For real field work connect an external Bluetooth or UDP receiver: accuracy from 0.5 m down to 1 cm with RTK, update rate up to 10 Hz. ColDonAgro works with any external GPS antenna, including third-party ones.

FREE AND PAID
Basic guidance features are free with any antenna. With Novator, Novator Sensor and Novator Pro RTK antennas the license key is built into the antenna firmware and unlocks all advanced features with no subscription.
