Network Transportation of RTCM Internet Protocol

The NTRIP is an RTCM standard designed for disseminating GNSS correction data (e.g. in the RTCM-104 format) or other kinds of GNSS streaming data to stationary or mobile users over the Internet, allowing simultaneous PC, Laptop, PDA, or receiver connections to a broadcasting host. NTRIP supports wireless Internet access through Mobile IP Networks like GSM, GPRS, or EDGE. The definitive source for all things NTRIP is from the BKG i.e. the Bundesamt für Kartographie und Geodäsie or the German Federal Agency for Cartography and Geodesy. See the GNSS Internet Radio section for details.

The NTRIP is utilized in Can-Net when you log in. A table of correction sources is displayed to you, you select which correction source you wish to use then log-in with a valid username and password. This is all handled with the NTRIP protocol. All major GNSS manufactures use this protocol.

The NTRIP protocal software consists of the following elements:

• NtripSources, which generates data streams at a specific location.
• NtripServers, which tranfers the data streams from one or multiple source to the NtripCaster
• NtripCaster, the major system component
• NtripClient, accesses the data streams of desired NtripSource on the NtripCaster
