RTCM 10410.1 Standard for Networked Transport of RTCM via Internet Protocol (Ntrip) Version 2.0 with Amendment 2, January 12, 2021

Networked Transport of RTCM via Internet Protocol (Ntrip) is an application-level protocol that supports streaming Global Navigation Satellite System (GNSS) data over the Internet. Ntrip is a generic, stateless protocol based on the Hypertext Transfer Protocol HTTP/1.1. The HTTP objects are extended to GNSS data streams.

This new standard describes Ntrip Version 2.0. 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; and
Provides for Real Time Streaming Protocol (RTSP) communication.

Even though Version 2.0 is intended to replace Version 1.0 (RTCM 10410.0), RTCM will continue to make RTCM 10410.0 available for users who have not upgraded to the new standard.

Amendment 2 clarifies NtripServer to NtripCaster communication protocol.
