Real Time IGS PPP Performance Report 11-09-01

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 AC 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) 
while using only GPS observations. 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:
