Harxon: Precision GNSS solution for robotic lawn mowers

Accurate position information

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. In robotic lawn mowers applications which utilise precise RTK positioning solution, antenna is the key part. Harxon provides high-precision GNSS antennas and high performance wireless data links that are customised and easy to be integrated, meeting the needs of high-precision positioning, communication and miniaturisation of robotic lawn mowers.

Features

1. High precision positioning

Harxon high precision embedded GNSS antennas feature full frequency, stable phase centre, wide beam width, exceptional low elevation satellite tracking performance. With improved signal filtering and excellent multi-path rejection, the antennas can provide reliable and consistent positioning services up to millimetre level across full bandwidth.

2. Reliable signal tracking

Robotic lawn mowers often have to work in areas with poor GNSS signal coverage. To solve this problem, Harxon provides high performance wireless data radio to receive correction data. The radio has superior transceiver performance and strong signal penetration ability, no fear of any nearby blockage. With strong anti-interference algorithm and adaptive network communication, connection distance up to 1km can be covered with complete signal coverage.

3. Easy to be Integrated and customisable

Both the antenna and the radio modem are designed to be small size, light weight and low power consumption, the radio modem is even as small as a SIM card. Their powerful system compatibility makes them easily to be integrated into robotic lawn mower positioning system without internal mutual interference. Also, they are customisable in cable and connector.

4. Affordable positioning solution

Harxon ready-to-use solution consists of embedded GNSS antenna and wireless data radio, involving satellite signal reception and differential data broadcasting and reception. Harxon positioning solution is compatible with most of the GNSS modules in the market. They can be integrated into existing systems or added to current devices, which can be directly used after being integrated. This solution save costs in system updating and maintenance, without the need of setting up expensive CORS system.
