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

1. Site Identification of the GNSS Monument
Site Name : O'Higgins / Antarctica
Four Character ID : OHI3
Monument Inscription : Pillar K3
IERS DOMES Number : 66008M006
CDP Number :
Monument Description : PILLAR
Height of the Monument : 1.4
Monument Foundation : CONCRETE PILLAR BOLTED ON BEDROCK
Foundation Depth : 0.5
Marker Description : SURVEY MARKER WITH THREAD
Date Installed : 2002-02-07T00:00Z
Geologic Characteristic : Bedrock
Bedrock Type : Metamorphic
Bedrock Condition : Weathered
Fracture Spacing : 50-200 cm
Fault zones nearby : (YES/NO/Name of the zone)
Distance/activity : (multiple lines)
Additional Information : Predominant rocks at the station
: O'Higgins are quartz-bearing black,
: grey and reddish brown
: low-metamorphic clay slates and
: phylitte slates of the Trinity
: Peninsula Formation. They are very
: brittle, fine-laminated in the mm-
: and cm-range and incline with about
: 60 to 80 degrees to NW.
: Because of these characteristics
: and the high clay mineral content
: and the expansive force resulting
: from this the slates are highly
: susceptible to weathering and mostly
: covered by detrital layers. Only
: tectonicly less stressed parts and
: parts resistant to weathering stick
: out from these detrital masses. These
: have a linear geometry and show strong
: cleavings. The instrusions of 0.5m to
: 1.5m thick vein rocks, which pass
: through the slates, are significantly
: younger. The pillar with the antenna
: is bolted into one of these veins,
: which are very resistant to weathering.
: An ASHTECH Z18 GPS+GLONASS operated
: from 2001-02-09 until 2003-01-27 at
: the ERS/VLBI-Station GARS O'Higgins /
: Antarctica with the four character ID
: OHIZ, DOMES Number 66008M004.
: Because of the expansion and of
: construction works in the Chilenean
: Antarctic Base the antenna
: for the GPS+GLONASS Permanent Tracking
: Station OHIZ was moved to another
: pillar K3, DOMES Number 66008M006.
: Number 66008M005, 2003-02-06,
: new four character ID OHI3.
: In addition and parallel also a
: ROGUE SNR-8000 / ACT SNR-8000 ACT
: operated from 1995-02-14 until
: 2002-02-20 at the ERS/VLBI- Station
: GARS O'Higgins / Antarctica with the
: four character ID OHIG, on pillar K5,
: DOMES Number 66008M001.
: Because of the expansion and of
: construction works in the Chilenean
: Antarctic Base the antenna for the
: GPS Permanent Tracking Station OHIG
: was moved to another pillar K6, DOMES
: Number 66008M005, 2002-02-14,
: new four charcater ID OHI2.
: For collocation we observed from
: 2002-02-14 until 2002-02-20 with two
: AOA SNR-8000 ACT at OHIG and OHI2,
: and also with the Ashtech Z-18 OHIZ.
: 2002-02-14 OHI2 installed.
: 2002-02-16 DOME removed in OHIG.
: 2002-02-19 DOME installed in OHI2.
: 2002-02-20 OHIG removed.
: 2003-01-27 OHIZ removed.
: 2003-02-06 OHI3 installed.
: An AOA SNR-8000 ACT observed until
: 2007-11-12 at OHI2 and was replaced
: with a JPS E_GGD.
: From 2004-03-16 until 2009-11-23 a
: JPS E_GGD or a TPS_GGD, from 2009-11-23
: until 2012-02-09 a LEICA GRX200GGPRO was
: operating at OHI3.
: Since 2012-02-09 a LEICA GRX1200+GNSS
: is operating.
