How GNSS antennas can increase farming accuracy

GNSS antennas are integral to the operation of advanced agricultural technologies such as Unmanned Aerial Vehicles (UAVs), field robots, robotic lawn mowers and autonomous tractors, enabling precise operations and navigation. As a leading brand of GNSS positioning antenna solution provider, Harxon provides high precision GNSS antenna solutions for various applications.

For UAVs

UAVs have become a transformative technology in agriculture. Many operations like crop monitoring, spraying, planting and data collection are involved in high precision GNSS antennas. It enables the UAV to navigate by determining its position, altitude, and speed, which can be used for tracking or guiding the UAV remotely, often in combination with an automated guidance system.

Harxon provides a series of multifunctional helix antennas with low weight, small size and low power consumption. Available in single, dual, triple, and full-band GNSS configurations, these antennas deliver millimetre-level positioning accuracy, ideal for UAV engineers and system integrators.

For field robots

The integration of GNSS antennas in field robots enhances precision and efficiency in various farming operations. It provides precise location data, enabling field robots to perform tasks like seeding, fertilising, and harvesting with pinpoint accuracy.

With accurate GNSS data, field robots can optimise their routes, reducing overlap in tasks such as spraying, which conserves resources and time. For these field robots, Harxon provides survey GNSS antennas with flexible installations (magnetic mount, screws mount and pole mount) and ruggedised GNSS antennas with IP69K rugged housing and metal base, enabling it to withstand high shock and vibration.

For robotic lawn mowers

Robotic lawn mowers are gradually becoming the main development direction of the lawn mower industry. Positioning, navigation and obstacle avoidance are the key points of robotic lawn mowers. Fusion positioning technology, such as RTK+ultrasonic/IMU/vision, is one of the mainstream technologies for lawn mowers at present.

The fusion of RTK technology and various sensors can provide accurate position information up to centimetre level in real time, allows for the generation of a virtual lawn line, route planning, and obstacle avoidance. Harxon provides OEM GNSS antennas, radio modems and RTK modules that are customised and easy to be integrated, meeting the needs of high-precision positioning, communication and miniaturisation of robotic lawn mowers.

For autonomous tractors

Auto steering systems are the key to achieving precision farming for tractors. These systems use GNSS and RTK technologies to navigate tractors and other farm machinery with sub-inch (2.5cm) precision, ensuring that every pass is optimally aligned. And GNSS smart antenna is the crucial part in the data collection process of auto steering systems.

Harxon provides high performance smart antennas, which are responsible for collecting positional data and processing signals from satellites and differential links to determine the exact position. Agriculture OEMs, integrators that develop precision ag solutions, and autonomous solution providers can integrate Harxon smart antenna into the precision agriculture system in many applications, including semi-autonomous or autonomous applications.
