Hello Frank, thank you for the information on your tests. Your tests seem to 
indicate that the use of the SAA correction model results in the removal of 
approx. 2.5 mm rms orbit error in the radial direction for the SLR/DORIS orbits. 
Good !

The Z bias comparisons with independant orbits is worrying. Yet, I do not 
understand in your plots why the comparison of SAA-corrected SLR+DORIS orbits 
with SLR+XOVER orbits shows almost no bias jump at the change of DORIS USO, 
while the comparison with JPL GPS orbits shows a big jump...

Regards,

Jean-Michel
