Transforms a smartphone or tablet into an in-cab guidance system that plots and follows straight AB lines and curved trajectories for field passes. GROMKO GPS, from GROMKO GPS, targets farmers and tractor operators needing mobile precision navigation for tasks such as spraying, sowing, and soil cultivation. Key capabilities include real-time processed-area visualization, field contour creation, and support for external high-precision GNSS receivers, making the app useful where accurate machine guidance and coverage tracking matter.

What can you use it for in everyday field work?

GROMKO maps and guides vehicle movement so operators can maintain prescribed passes during spraying, fertilizing, sowing, and cultivation, using AB straight lines, curved trajectories, and diagonal passes. The app shows processed area in real time and saves completed work in a log, which supports routine chores where avoiding overlap and ensuring full coverage are operational priorities.

How accurate and reliable is the location data?

The app supports connection to external Bluetooth or USB GNSS receivers for high-precision positioning, a design choice that raises accuracy above standard mobile GPS. Because the app accepts external antenna input, positioning depends on the quality of the connected GNSS equipment and its antenna placement, which is the intended path to achieve professional-grade guidance performance.

Does it work with standard Android devices without modification?

Available for Android, the app runs on smartphones and tablets and is recommended for use on tablet-sized screens for in-cab visibility. It operates through standard device connections to external receivers and does not require device modification, so operators can use existing mobile hardware plus a compatible GNSS module to reach the precision levels the developer targets.

What use cases and operational limits should operators expect?

GROMKO is designed for in-field navigation, contour creation, and coverage tracking during mechanically guided tasks; it records work for later review. Users are responsible for ensuring their use complies with platform terms and local regulations, and the app's accuracy depends on pairing with appropriate external GNSS hardware rather than on standalone phone positioning alone.

Who should adopt it and how to get the best results

GROMKO serves farmers and service providers who need in-cab, route-based guidance and processed-area tracking rather than a mapping app for general navigation. Expect professional performance when operating with a quality external GNSS and a stable tablet mount. A practical tip: mount the antenna where it has a clear sky view and secure the tablet to reduce vibration for consistent tracking during field passes.
