Real Time IGS PPP Performance Report 11-11-02

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 
continues over 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.

RMS of N/E/U 2D/3D displacements (m) from 60 min PPP tests:
