The '''Networked Transport of [[RTCM SC-104|RTCM]] via Internet Protocol''' ('''NTRIP''') is a [[Communications protocol|protocol]] for streaming [[differential GPS]] (DGPS) corrections over the [[Internet]] for [[real-time kinematic positioning]].

'''Ntrip''' was developed by the [http://www.bkg.bund.de/EN/Home/homepage__node.html__nnn=true German Federal Agency for Cartography and Geodesy] ('''BKG''') and the [http://www.cs.uni-dortmund.de/nps/en/Home/index.html Dortmund University Department of Computer Science]. '''Ntrip''' was released in September 2004 as [http://igs.bkg.bund.de/root_ftp/NTRIP/documentation/NtripPressRelease.pdf "RTCM Recommended Standards for Networked Transport of RTCM via Internet Protocol (Ntrip), Version 1.0"]. The current version of the protocol is [https://ssl29.pair.com/dmarkle/puborder.php?show=3 Version 2.0 with Amendment 1, June 28, 2011].

The specification is standardized by the [[Radio Technical Commission for Maritime Services]] (RTCM).<ref>{{cite web |url=http://igs.bkg.bund.de/ntrip/about|title=about NTRIP|accessdate=17 January 2012}}</ref>

'''NTRIP''' is an [[open standard]] protocol. The protocol can be freely download from [http://igs.bkg.bund.de/root_ftp/NTRIP/documentation/NtripDocumentation.pdf '''BKG'''] and there is an [[open source]] implementation available from [http://software.rtcm-ntrip.org/ software.rtcm-ntrip.org].
