Ladies and Gentlemen

My colleagues Christian Ploetz and Christian Schade
arrived in the German Antarctican Receiving Station
GARS O'Higgins.

They detected an alignment of the antenna for the
OHI3 GNSS Permanent Tracking Station to West,
instead to North, 2013-02-07.

This maybe happened 2012-09-22 when a strong storm
threw the antenna from the pillar and a broken adapter screw
in the mounting of the antenna was replaced.

My colleagues also did a control survey, 2013-02-07.
The result for the antenna height, Marker-> ARP Up Ecc.
of this control survey is 000.0660 m.
Maybe the antenna height changed alredady 2012-09-22
from 000.0668 to 000.0660, but nobody knows ?

We already sent an Update of the OHI3 Site Information
Form ohi3_20130213.log to the IGSCB.

With best regards
Rudi
