The Network Transport of RTCM via Internet Protocol(NTRIP) is a protocol that enables the streaming of GNSS or RTK correction data over the internet. NTRIP is designed to broadcast differential correction data to GNSS receivers like the UNI-GR1. With this correction data the UNI-GR1 can be centimetre accurate.
The three major parts of NTRIP: The NTRIP-Client, the NTRIP-Server and the NTRIP-Caster:
Mar 13, 2011 The Lefebure NTRIP Caster software includes the ability to connect to one serial port and make that data available via on the NTRIP caster. In this scenario, the Caster will commonly live in an office or home, physically close the the base station. The Trimble Networked Transport of RTCM via Internet Protocol (NTRIP) Caster App is designed to create and manage the administration of multiple NTRIP casters for streaming services as well as to provide a view of current and historical login access. SNIP is a Networked Transport of RTCM via Internet Protocol (NTRIP) Caster application that combines user-friendly software with an active data-pushing feature to bring you all the benefits of NTRIP technology. Used by thousands of deployments world-wide, SNIP is the Caster of choice for most networks. SNIP even offers a fully featured starter.
NTRIP Server
The NTRIP-Server is a computer running NTRIP Server software and communicates directly with a GNSS reference station. The NTRIP-Server serves as the medium between the GNSS receiver (NTRIP Source) streaming RTCM data and the NTRIP Caster.
NTRIP Caster
The NTRIP-Caster is a HTTP server which receives streaming RTCM data from the NTRIP Servers and in turn streams the RTCM data to one or more NTRIP-Clients via the internet. The client in the diagram below is you while using the UNI-GR1.

NTRIP Caster Setup | Lefebure
The NTRIP-Client receives RTCM data from the NTRIP-Caster to apply as real-time corrections to a GNSS receiver like the UNI-GR1. On the NTRIP-Caster you can set your preferred mountpoint like “PRSRTCM3” to finally receive your correction data from the NTRIP-Caster. This can be done in the UNI-Connect.
