XY621R is a full-frequency high-precision positioning receiver product designed and produced by our company that supports BDS/GPS/GLONASS/Galileo/QZSS full system, which adopts a ruggedized package, which can easily integrate the UAV positioning system and provide accurate positioning data interface for UAV navigation and positioning. This full-system multi-frequency high-precision positioning receiver has a network port. The external interface communication interface is a standard serial communication interface UARTRS232. Reliable packaging and flexible communication make the RTK easier to operate, and at the same time make the receiver more suitable for surveying and mapping, earthquake, UAV precise positioning, scientific research and other high-precision measurement and positioning applications, this indicator will be described with the built-in OEM729.
