Beitian wireless data transmission module GNSS antenna GNSS receiver BT-940N 940U

Description: The receiver supports GPS L1C / A L2C, GLONASS L1OF L2OF, GALILEO E1B / C E5b, BDS B1I / B2I. RX can be used to input commands, change the baud rate, frequency, output sentence and other parameters for GPS. The receiver supports centimeter-level high-precision RTK differential positioning. The receiver can be used as a base station or a mobile station. If it is used as a base station, it only needs to be configured into the base station mode through instructions. The purpose of the base station is to be responsible for sending RTCM data to the mobile station in a wireless transmission mode through a wireless data transmission station. If it is used as a mobile station, it can be directly used as a mobile station without any configuration. The mobile station first receives the RTCM data of the host station through the receiving end of the wireless data transmission radio station, and then calculates, it can enter the RTK differential positioning mode, and the accuracy can reach centimeter-level positioning. The default baud rate of the module is 38400bps. If the frequency is increased, the baud rate will be increased accordingly, otherwise the data volume will be too large to transmit. In addition, the frequency is recommended not to exceed 5HZ. The RTK light of the mobile station does not enter the RTK mode, and the light is off; enter the RTK Float mode, the blue light flashes; enter the RTK Fixed mode, the blue light is always on. The RTK light of the host station will be off at any time. Support custom development.
