AgriBus: GPS farming navigator is an Android-based GPS guidance system for agricultural machinery such as tractors, combines, and self-propelled sprayers. The app helps farmers perform straight line tasks in the field by displaying real-time information to create evenly spaced straight lines in large fields. Developed by Agri Info Design Ltd., the app is based on a software "Agricultural Vehicle Navigation Software for Field Operation" and a patent "JPB2" developed by National Agricultural Research Organization (NARO).

The app assists farmers by showing the difference between the current position and the base line, allowing them to perform farming work in a straight line. The app can operate using the inbuilt GPS of a smartphone or tablet, but it is strongly recommended to use an external GNSS/GPS via Bluetooth/USB connection for higher accuracy. The app is available as a free download, but an ad-free subscription is also available for about $60/year = $5/month. A version with field and task management functionality is planned for release in the near future.
