	Unlike other [[GNSS Augmentation]] systems as SBAS or GBAS, DGNSS is not used for civil aviation, but for urban transportation and in offshore areas. Therefore, the standards applying to DGNSS systems are the ones of data transmission standards defined by the Special Committee 104 on DGNSS of the [http://www.rtcm.org/~~overview~~.~~php#Standards~~ Radio Technical Commission for Maritime Services] (RTCM). Except for RTCM, there exist other proprietary DGPS standards, such as [http://www.trimble.com Trimble] [http://trl.trimble.com/docushare/dsweb/Get/Document-469944/WhitePaper_HeavyHighway_CMRxrev1.pdf Compact Measurement Record] (CMR).

	The internationally accepted data transmission standards for DGNSS are defined by RTCM, particularly by its Special Committee SC-104. 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 [http://www.rtcm.org/~~overview~~.~~php#Standards~~ Radio Technical Commission for Maritime Services] (RTCM) and has become an industry standard for communication of correction information. Note that RTCM is a binary data protocol.		The internationally accepted data transmission standards for DGNSS are defined by RTCM, particularly by its Special Committee SC-104.

	The Compact Measurement Record (CMR) was developed by and initially used by [http://www.trimble.com Trimble] in 1992. The format was developed as a method of transmitting code and carrier phase correction data in a compact format from GPS base stations to GPS rovers for [[Real Time Kinematics\|RTK]] GPS surveying. Dr. Nicholas Talbot of Trimble publicly introduced the ~~[http://gpsd.googlecode.com/files/Trimble-CMR.pdf~~ CMR format] at the 1996 [http://www.ion.org/ Institute of Navigation] (ION) Conference.

	The RTCM 10402.3 standards defined the messages for differential correction information. There are 64 types of messages. The message format is a sequence of 30 bits. The messages 1 to 17 are available in older RTCM versions, while messages 18-21 have been added in version 2.3 to made the standard applicable to [[~~Work in Progress:~~Real Time Kinematics\|RTK]] corrections.
