Subject: [Fwd: Re: [IGSMAIL-6078]: Old SVN35 reactivated]

Dear colleagues,

as you can see from the email attached below, the old GPS-35 equipped
with an SLR retro-reflector array has been re-activated recently (now
as PRN25). At CODE we process the microwave data of the satellite so
that we will provide predicted orbits that can be used by the ILRS
sites for SLR tracking.

Although we do not know how long GPS-35 will be active, we would be
glad if the ILRS sites resume to track GPS-35 (as proposed by Carey).

Best regards,
Daniela

Stefan,

Will AIUB resume providing SLR prediction files for GPS-35?
I.e., should the ILRS add the satellite back into our tracking
roster if possible?

Best regards,
Carey.
