    4 The BKG Ntrip State Space Server (BNS) is a program for transforming GNSS satellite clocks and orbits into corrections to Broadcast Ephemeris. These corrections are then encode in RTCM Version 3.x format and uploaded to NTRIP broadcasters like <u>http://www.euref-ip.net/home</u> or <u>http://www.igs-ip.net/home.</u> BNS is created as a tool for service providers with real-time access to a network of continentally or globally distributed GNSS reference stations.

    34 Differential GNSS and RTK operation using RTCM is currently based on corrections and/or raw measurements from single or multiple reference stations. This approach to differential positioning is using 'observation space' information. The representation with the RTCM standard can be called 'Observation Space Representation' (OSR).
