-BNC can derive coordinates for a rover position following the Precise Point Positioning (PPP) approach. It uses either code or code plus phase data in ionosphere free linear combinations P3 or L3. Besides pulling a stream of observations from a receiver, this also requires pulling in addition

 <li>a stream carrying satellite orbit and clock corrections to Broadcast Ephemeris in the form of 'State Space Representation' (SSR) messages as proposed by RTCM (i.e. premature message type 1060). Note that for BNC these correctors need to be referred to the satellite's Antenna Phase Center (APC). Streams providing such messages are listed on <u>http://igs.bkg.bund.de/ntrip/orbits</u>. Stream www.igs-ip.net:2101/CLK11 is an example.</li>
