NTRIP

NTRIP (Networked Transport of RTCM via Internet Protocol) is a protocol used for streaming corrections over the Internet from a base station to a rover to achieve cm-level accuracy.

The NTRIP system is made up of three primary software components:

• The NTRIP caster: an HTTP Internet service, acting as a line of communication between the NTRIP server and NTRIP clients.
• The NTRIP server base: transfers GNSS data corrections from the NTRIP server to the NTRIP caster.
• The NTRIP client rover: accesses GNSS data from the NTRIP caster for RTK positioning using single reference stations or RTK networks. Additionally, it sends request messages to the caster in order to receive data.
