RTCM Standard Logs
The Radio Technical Commission for Maritime Services (RTCM) was established to facilitate the establishment
of various radio navigation standards, which includes recommended GPS differential standard formats.
The standards recommended by the Radio Technical Commission for Maritime Services Special Committee 104,
Differential GPS Service (RTCM SC-104,Washington, D.C.), have been adopted by NovAtel for implementation
into the GPSCard. Because the GPSCard is capable of utilizing RTCM formats, it can easily be integrated into
positioning systems around the globe.
