r2193 r2194 941 941 BNC can derive coordinates for a rover position following the Precise Point Positioning (PPP) approach. It uses either code or phase data in ionosphere free linear combinations P3 or L3. Besides pulling a stream of observations from a receiver, this also requires pulling a stream of 942 942 <ul> 943 <li>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 refer to the satellite's Antenna Phase Center (APC). Streams providing such messages are listed on http://igs.bkg.bund.de/ntrip/orbits.</li>944 <li>Broadcast Ephemeris available as RTCM Version 3 message types 1019 and 1020. This is a must when the stream coming from the receiver does not contain Broadcast Ephemeris or provides them only at low repetition rate.
