How to configure Ntrip

Background information

Ntrip stands for Networked Transport of RTCM via Internet Protocol. Developed by the Federal Agency for Cartography and Geodesy of
Germany, Ntrip enables the streaming of GNSS data over the internet.
Ntrip is implemented in three system software components: Ntrip client, Ntrip server and Ntrip caster. The Ntrip caster is the actual
HTTP server program while Ntrip client and Ntrip server are acting as HTTP clients.
GR/GM receivers can act as:
•
Ntrip servers, sending GNSS data to an Ntrip caster. Leica GNSS Spider software can act as a caster. The receiver itself can
also act as an Ntrip caster
•
Ntrip clients, receiving real time correction data from an Ntrip caster. The Leica Viva rovers can act as an Ntrip client,
receiving correction data from an Ntrip caster
•
an Ntrip caster, receiving data streams from other receivers or e.g. Leica Spider software on several mount points and
distributing this data to different clients. Only one TCP/IP port is needed for the Ntrip caster to receive and distribute multiple
data streams
More information on Ntrip is contained in the Glossary topic, Ntrip.

Before you begin

Ntrip is a very easy way to distribute GNSS data to a high number of users via only one single TCP/IP port. GR/GM receivers can act as
Ntrip casters, Ntrip clients and Ntrip sources. To use the different Ntrip functionalities on a receiver, follow the Step-by-Step guide
below.
