Networked Transport of RTCM via Internet Protocol
NTRIP, Version 1.0
The material provided here describes the Ntrip real-time GNSS data transport protocol definition and the description of an Ntrip Example Implementation. In September 2004 Ntrip Version 1.0 became an RTCM Recommended Standard, see Press Release. Note that the protocol definition made available here is not the official Ntrip documentation. This can only be ordered through http://www.rtcm.org. Further Ntrip versions are issued by RTCM when necessary.
NTRIP, Version 2.0
In June 2009 RTCM Special Committee 104 (SC104) has completed a Version 2.0 of its Ntrip standard, see Press Release. Major changes compared to Version 1.0 are:
- Cleared and fixed design problems and HTTP protocol violations
- Replaced non standard directives
- Adds chunked transfer encoding
- Improves header records
- Provides for sourcetable filtering
- Provides for Real Time Streaming Protocol (RTSP) communication
