The NTRIP transport protocol provides an additional method for accessing global GNSS data in real-time and will thereby augment the existing RTIGS global network. NTRIP has the potential to disseminate the upcoming RTIGS products over the Internet to stationary or mobile users worldwide. The new protocol is called "Networked Transport of RTCM via Internet Protocol" (NTRIP) and it is also capable of streaming any kind of GNSS data. At the same time, under the auspices of the "Radio Technical Commission for Maritime Services" (RTCM), GNSS vendors developed and finally agreed, in September 2004, on a new protocol for streaming GNSS data. Software packages including the RTIGS s udprelay, udparchiver and MulticastReader have been in use for several years and have been proven to meet the demands for real-time GNSS product generation based on data from globally distributed reference stations. RTIGS GNSS data streams are available in a format that incorporates the JPL SOC format for data compression.
The protocol makes use of the UDP transport protocol and is capable of transmitting any type of data or product. Introduction The Real-Time IGS Working Group developed the RTIGS protocol for streaming GNSS data over the open Internet. Check out our video tutorial on how to connect your Reach RS2 to NTRIP and work with correction data sent over a cellular modem.1 Streaming Real-Time IGS Data and Products Using NTRIP Georg Weber Federal Agency for Cartography and Geodesy (BKG), Frankfurt, Germany 1. Once you’ve completed the registration, you can use your credentials to connect your rover to the NTRIP network and receive connections. You’ll also need a username and password to log into the network. Once you’re registered, you’ll get a particular port and IP address to access and get authorized by the network. The service allows working with one base and one rover at a time free of charge. It takes just a few steps to register and acquire the data for your personal mount point. We have our own NTRIP caster-it has a user-friendly interface that helps you to quickly get credentials and enter them in the ReachView app.
Some of the NTRIP networks are run by states, some are free of charge, some of them are private and are pretty costly when it comes to the subscription fees. To get access to the NTRIP network, you need to contact your local NTRIP service to create an account.
