The Networked Transport of RTCM via Internet Protocol (NTRIP) is a protocol for streaming differential GPS (DGPS) corrections over the Internet for real-time kinematic positioning. NTRIP is a generic, stateless protocol based on the Hypertext Transfer Protocol HTTP/1.1 and is enhanced for GNSS data streams.[1]
The specification is standardized by the Radio Technical Commission for Maritime Services (RTCM).[2] NTRIP was developed by the German Federal Agency for Cartography and Geodesy (BKG)[3] and the Dortmund University Department of Computer Science.[4] Ntrip was released in September 2004.[5] The 2011 version of the protocol is version 2.0.[6]
NTRIP used to be[7] an open standard protocol but it is not available freely (as of 2020). There is an open source implementation available from software.rtcm-ntrip.org from where the protocol can be reverse-engineered.
