NMEA data is widely used in surveying applications to exchange positioning information between GNSS receivers and external devices or software platforms. Depending on the application requirements, NMEA data can be transmitted through different communication methods, such as serial ports, Bluetooth, or network connections.

In RTK operations, the performance of the data link directly affects positioning stability and user experience. When using network-based corrections, users may encounter different transmission protocol options such as TCP and UDP. Our products such as Orion One, X1, and SV100 support both protocols.
