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.
The GR/GM Series receiver can act as:
• an Ntrip Server, sending GNSS data to an Ntrip caster. Leica GNSS Spider software can act as a caster. The GR
receiver itself can also act as an Ntrip caster
• an Ntrip client, 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. The GR/GM Series
receiver can act as an Ntrip caster, Ntrip client and Ntrip source. To use the different Ntrip functionalities on the GR/GM series
receivers, please follow the Step-by-Step guides below.
