<p class="MsoNormal">I noticed in our rapid processing that the
biases from GPS-51/G20 have jumped.

<p class="MsoNormal">Digging into this I noticed that we all of
a sudden have C2L and C2X data although this is an old BLOCK
IIR-A satellite!? These are incapable to transmit these
signals. Nevertheless there are at least 40 IGS stations
reporting C2L/C2X data from this satellite. So it seems pretty
real. The satellite is flagged as unhealthy and according to
the NAGU 2026006 from January 8, 2026, it is officially
decommissioning. So no clue what is happening to this
satellite. Scientifically it may be interesting to see if the
old satellites can somehow transmit C2L/C2X signals…. The data
of the satellite looks fine both 2W and 2L/2X.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">If anybody knows what is going on with the
satellite I am very interested to learn about it.<o:p></o:p></p>
