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 m Monument Foundation : CONCRETE PILLAR BOLTED ON BEDROCK Foundation Depth : 0.5 m Marker Description : SURVEY MARKER WITH THREAD Date Installed : 2002-02-07T00:00Z Geologic Characteristic : Bedrock Bedrock Type : METAMORPHIC Bedrock Condition : WEATHERED Fracture Spacing : 51-200 cm Fault zones nearby : Distance/activity : 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, : from 2012-02-09 until 2014-03-01 a : LEICA GRX1200+GNSS was operating at : OHI3. : Since 2014-03-01 a LEICA GR25 : is operating. 2.
