Site Identification of the GNSS Monument Site Name : O'Higgins / Antarctica Four Character ID : OHIZ Monument Inscription : IERS DOMES Number : 66008M004 CDP Number : Monument Description : STEEL PLATE Height of the Monument : 0 Monument Foundation : STEEL PLATE FASTENED ON CONTAINER ROOF Foundation Depth : 0 Marker Description : MARKER ON STEEL PLATE Date Installed : 2001-02-09T01:00Z 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. : 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. : The antenna was installed on a steel plate : fastened to the roof of a container, : 2.3 m above the ground. : 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 charcater 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. 2.
