High-precision GNSS multi-frequency centimeter-level low-power UBLOX ZED-F9P RTK differential GPS module

product description

The company's AK314 Beidou/GPS/Galileo/Glonass/QZSS four-mode dual-frequency RTK board (hereinafter referred to as the board) is an ultra-low-cost, low-power, high-performance real-time dynamic differential positioning board. The highly reliable carrier phase difference technology of the board can provide real-time centimeter-level positioning accuracy for drones, automobiles, and surveying and mapping users. The board can be configured for "rover" or "reference station" operation. Through the joint observation of the "mobile station" and the "reference station", the carrier phase difference technology is used to eliminate various measurement errors such as ephemeris error, ionospheric error, tropospheric error, inter-satellite clock error, etc., and finally obtain high-precision positioning results. The board is configured as a "reference station", and the differential interface outputs RTCM 2.x/3.x standard data streams, which are compatible with most commercial mobile stations on the market. At the same time, a reference design of network RTK is provided, which can distribute the differential data stream to all mobile stations through the network. The board is configured as a "mobile station", and the differential interface supports RTCM 2.x/3.x differential data format, which can be connected to the user's existing reference stations of other brands or access to the national Beidou ground-based enhancement system. The static relative positioning accuracy of the board is less than 1cm, the medium dynamic relative positioning accuracy is less than 5cm, and the output rate is 1~10Hz. It can be used in a variety of scenarios and has a very high cost performance.

Product Features
