AB: The global Internet can be used for the real-time collection and exchange of GNSS data, as well as for broadcasting derived differential products. The EUREF community decided in June 2002 to set up and maintain a real-time GNSS infrastructure on the Internet using stations of its European GPS/GLONASS Permanent Network EPN. A pilot project was established called EUREF-IP (IP for Internet Protocol). This real-time GNSS data service uses a new dissemination technique called "Networked Transport of RTCM via Internet Protocol" (Ntrip). Ntrip stands for an HTTP application-level protocol streaming GNSS data over the Internet. Currently about 110 data streams are available through EUREF-IP Ntrip Internet Broadcaster. This paper introduces the EUREF-IP Ntrip Broadcaster with its available real-time data streams from different networks. It focuses on positioning accuracy as well as on data latency, monitoring aspects and standardization.
