Equipped with a high-precision GNSS engine, the S20 offers full-constellation tracking and versatile work modes. When without base stations, it attains 15cm pass-to-pass accuracy in single-point smooth mode, 20cm accuracy in HAS-PPP mode, and 0.6m accuracy in SBAS mode. In RTK mode, it delivers centimeter-level accuracy for precision navigation.
The S20 receiver integrates the GNSS antenna and GNSS module together, largely streamlining the system components and installation. By simply installing the S20 on the top of vehicles, users can easily obtain accurate positioning, which is specially designed for precision agriculture and vehicle navigation.
The S20 boasts broad compatibility with various tractor and vehicle models, requiring no specific vehicle prerequisites. Featuring a standard DB9 serial port and NMEA-0183 message output, it facilitates seamless integration into navigation system development, ensuring high adaptability and ease of use.
