Ladies and Gentlemen

According to an information from Leica
"If a GR10/25 receiver with ME FW <= 6.521, e.g. 6.521
is configured to track all satellite systems, the receiver
might experience a complete total loss of lock, leading
to a lost position and will not recover automatically",
my colleague Uwe Hessels upgraded the firmware in
the LEICA GR25 in the OHI3 GNSS Permanent Tracking
Station O'Higgins / Antarctica from 3.22/6.521 to
3.22/6.522, 2016-04-27T13:00Z.

Because of problems with the external frequency
from the H-Maser EFOS 50 the LEICA GR25 is operating
with the internal frequency.
