The Networked Transport of RTCM via Internet Protocol (NTRIP) is a protocol for streaming differential GPS (DGPS) data over the Internet in accordance with specification published by RTCM.[1] NTRIP is a generic, stateless protocol based on the Hypertext Transfer Protocol HTTP/1.1 and is enhanced for GNSS data streams.[2]

NTRIP was developed by the German Federal Agency for Cartography and Geodesy (BKG) and the Dortmund University Department of Computer Science. Ntrip was released in September 2004 as "RTCM Recommended Standards for Networked Transport of RTCM via Internet Protocol (Ntrip), Version 1.0". The current version of the protocol is Version 2.0 with Amendment 1, June 28, 2011.

NTRIP used to be[3] 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.
