BKG Professional NtripCaster (Datasheet)

Application and Specifications

The BKG Professional NtripCaster allows the dissemination of GNSS real-time data streams via internet. The software supports the Ntrip internet protocol in version 1 and 2. For more details on the Ntrip protocol, please see here.
The software has been developed within the framework of the EUREF-IP project. It is based on the ICECAST Internet Radio software written in C programming language under GNU General Public License (GPL). The caster is running on Linux systems and has been tested successfully on various distributions, such as Suse, Debian, Gentoo, and Red Hat. The software supports more than 100 NtripServers and more than 2000 listening NtripClients simultaneously. There are more than 100 operational installations worldwide. For technical details, see the manual and Changelog for updates and security fixes.

The caster does NOT support features known from legacy RTK services like Virtual Reference Station (VRS) or selection of the nearest base station etc. The software does not decode streams and has therefore no information about the streams' content. For positioning purposes the caster can be used to distribute SSR correction streams, see RTCM-SSR corrections.
