Real Time IGS PPP Performance Report 12-07-03 Prepared by BKG RTIGS Group The following table shows RMS values for North, East, Up, 2D and 3D displacements of real-time PPP tests when using a selection of orbit/clock correctors streams provided by Real Time (RT) IGS Analysis Centers (ACs). Tests are performed every day simultaneously for all streams in fully kinematic mode and for a set of globally distributed RTIGS sites. Each individual test lasts 60 minutes and is carried out with the BKG Ntrip Client (BNC). Presented RMS values are based on average displacements over the last 5 minutes of each test. Tests influenced by stream outages remain unconsidered.
