Robotic Lawn Mowers

The high-precision positioning system for robots typically consists of a base station and a rover unit. The rover is embedded within the robot terminal, and it can receive differential data via three solutions: a dedicated differential datalink, access to a local CORS network, or through a self-established CORS infrastructure. Harxon offers a versatile range of GNSS antennas tailored for such systems— basic GNSS-only models, all-in-one designs that combine GNSS with 4G/5G/Bluetooth/WiFi/radio, smart antennas integrated with RTK modules, enabling centimeter-level accuracy and reliable guidance in dynamic environments.

Smart Antenna

The Smart Antenna series combines Harxon’s world-leading antenna technology with Unicore’s full-constellation, full-frequency RTK positioning modules. The HX-ME401A and HX-ME402A deliver precise positioning performance in a compact, integration-ready structure. These modules provide single-point meter-level accuracy, DGPS sub-meter-level accuracy, and RTK centimeter/millimeter-level accuracy, making them well-suited for integration into robotic lawn mower navigation and positioning systems. The antenna and module are well compatible with each other, simplifying the development process and reducing costs for engineers, which greatly improves the overall reliability of the application.

OEM GNSS Antenna (Multi-Function)

In large or complex terrains, intelligent robots demand precise positioning and reliable remote communication. Harxon's integrated GNSS+radio antenna solutions deliver centimeter-level positioning accuracy through GNSS and stable wireless communication with the base station and other devices in the 858–878 MHz/902–928 MHz frequency bands. This compact design simplifies system integration, reduces production costs, and ensures space efficiency with excellent electromagnetic compatibility, meeting the navigation and communication needs while enhancing autonomy and efficiency.

OEM GNSS Antenna

Harxon OEM GNSS antennas feature full frequency, stable phase center, wide beam width, and exceptional low elevation satellite tracking performance. With improved signal filtering and excellent multipath rejection, the antennas can provide reliable and consistent millimeter level positioning accuracy across full bandwidth. HX-CSX014A and HX-CSX231A are cost-effective options for robotic lawn mowers characterized by small size, light weight and low power consumption. The powerful system compatibility makes them easily to be integrated into robotic lawn mower positioning system avoiding interference with other components.

Radio Modem

Radio modem sends and receives differential correction data, enabling the mower to communicate over long distances, which is essential for the robotic lawn mower to achieve precise positioning. HX-DU1021D is a high performance radio modem for lawn mowers with frequency range between 868/915MHz ISM band. It stands out for mini size, low power consumption, long range communication, excellent receiving performance and strong anti-interference capacity. The small radio modem can be integrated into existing systems or added to current devices, which can be directly used after being integrated.
