Thanks for the hint, Jon !

I tried a number of variants for your IGS 9 orbits, adjusting MA
(incorrectly labelled AOP) or MM.
Also the IGS 10 estimation adjusted in MA.
The best match is your IGS 9 payload with .0087 subtracted from MM.

IGS 9 payload                                            505 X 511 km
1 71002U 15602A   15032.22709490 0.00030000  00000-0  00000+0 0    05

Strangely the obs of Björn gives me high residuals. I've checked it
