Network Transport of RTCM via Internet Protocol (Ntrip) is a protocol for streaming differential data over internet. It includes:

·         Ntrip Source: Provide differential data and send to Ntrip Server

·         Ntrip Server: Send data to Ntrip Caster

·         Ntrip Caster: Data management center, receive and send data

·         Ntrip Client: Download data from Ntrip Caster

Normally the Ntrip Source and Ntrip Server are integrated into the GNSS receiver, basically we call it [Base/Reference Station]. Ntrip Caster is normally a software running on the computer. And Ntrip Client is normally called [Rover].
