Dear Colleagues





As reported in the last paper of D. Kucharski  et.al. a group of SLR
stations, including Riga, are tracking a few dead satellites apart of
ENVISAT.



Last night our observer tracked OICETS using the Graz cpfs for 20180316,
we filtered it this morning using the Graz cpfs for 20180317 and found a
timebias of



-81 ms.



There are only 2 OICETS passes done this year: 7811 BORL in Jan. 8th and
ours yesterday night.



We hope this information will help the other participating stations to
successfully track OICETS.

More data is needed!



The Riga team.<div dir=&#8221;ltr&#8221;>
