Standards: Differing from SBAS and GBAS augmentation systems, DGNSS is not used for civil aviation. Therefore, there are no standards coming from IACO. The internationally accepted data transmission standards for DGPS are defined by RTCM (Radio Technical Commission for Maritime Services), particularly by its Special Committee SC-104. Currently version 2.3 of the DGPS standard is widely used. At the time of this writing (May 2005), the new version of the standard, 3.0, has recently been released. The version of RTCM3.0 for Galileo is now in the making. Except for RTCM, there exist other proprietary DGPS standards, such as Trimble’s CMR. (taken from septentrio webpage)
RTCM SC-104 is a standard that defines the data structure for differential correction information for a variety of differential correction applications. It was developed by the Radio Technical Commission for Maritime services (RTCM) and has become an industry standard for communication of correction information. RTCM is a binary data protocol
