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 : Monument Foundation : Foundation Depth : Mark Description : MARKER BOLT Date Installed : 2001-02-09T01:00Z Geologic Characteristic : Bedrock Bedrock Type : Metamorphic Bedrock Condition : Weathered Fracture Spacing : 50-200 cm Fault zones nearby : Distance/activity : Notes : 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 Turbo : Rogue antenna is bolted into one of : these veins, which are very resistant : to weathering. Additional Information : An ASHTECH Z18 GPS + GLONASS System : operates since 09-FEB-2001, 01:00 UT, : in our Observatory in O'Higgins / : Antarctica. In addition and parallel : to the OHIG GPS Permanent Tracking : System (AOA SNR-8000 ACT or ROGUE : SNR-8000), which operated from : 14-FEB-1995 until 20-FEB-2002. And : to the OHI2 GPS Permanent Tracking : System (AOA SNR-8000 ACT), which : replaced OHIG 14-FEB-2002. 2. Site Location Information City or Town : O'Higgins State or Province : Country : Antarctic Peninsula Tectonic Plate : Antarctican Approximate Position (ITRF) X coordinate (m) : 1525872.392 Y coordinate (m) : -2432481.273 Z coordinate (m) : -5676146.066 Latitude (N is +) : -631914.61 Longitude (E is +) : -0575401.23 Elevation (m,ellips.) : 30.6 Additional information : The GPS / GLONASS-System was : installed nearby the German : ERS/VLBI-Station and the : Chilenian Base O'Higgins. : The System is a stand-alone-system : during long Antartican-Winter. : Only for VLBI-Observation-Sessions : operators travel to O'Higgins during : short Antarctican-"Summer". 3.
