Site Identification of the GNSS Monument Site Name : O'Higgins / Antarctica Four Character ID : OHI2 Monument Inscription : Pillar K6 IERS DOMES Number : 66008M005 CDP Number : (A4) Monument Description : (PILLAR/BRASS PLATE/STEEL MAST/etc) Height of the Monument : (m) Monument Foundation : (STEEL RODS, CONCRETE BLOCK, ROOF, etc) Foundation Depth : (m) Marker Description : (CHISELLED CROSS/DIVOT/BRASS NAIL/etc) Date Installed : 2002-02-14T18:30Z 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 Turbo : Rogue antenna is bolted into one of : these veins, which are very resistant : to weathering. : ROGUE SNR-8000 / ACT SNR-8000 ACT : operated since 14-FEB-1995 00:00 UT : until 20-FEB-2002 02:00 UT at the : ERS/VLBI- Station O'Higgins / : Antarctica with the four character : ID OHIG. Because of the expansion : and of construction works in the : Chilenean Antarctic Base we had to : move the antenna for the GPS Permanent : Tracking Station OHIG to another new : pillar K6 in our O'Higgins Observatory. : The four character ID for this new : antenna-site is OHI2. : A summary for OHIG follows on the : next lines, includes the transition to : OHI2. : Upgrading Firmware from V 3.0 : to V 3.2, 04-FEB-1996, 16:40 UT. : Malfunctiong ROGUE SNR-8000 S/N T319 : have been replaced by ROGUE SNR-8000 : S/N T398, 17-FEB-1997, 00:23 UT : (Firmware V 3.2 to V 3.32.4). : ROGUE SNR-8000 S/N T-398 have been : replaced by AOA SNR-8000 ACT : S/N T-395U (ROGUE SNR-8000 upgraded : to ACT, functionally like AOA : BENCHMARK ACT) V 3.3.32.3, : 14-FEB-2000, 00:35 UT. : Malfunctioning AOA SNR-8000 ACT : S/N T-395U (ROGUE SNR-8000 : upgraded to ACT) V 3.3.32.3 have : been replaced by ROGUE SNR-8000 : S/N T394 Firmware Version : 3.2.32.9, 02-OCT-2000. : ROGUE SNR-8000 S/N T394 Firmware : Version 3.2.32.9 have been replaced : by AOA SNR-8000 ACT (ROGUE SNR-8000 : upgraded to ACT) S/N T-395U, : V 3.3.32.3, 09-FEB-2001, 01:00 UT. : In addition and parallel also an : ASHTECH Z18 GPS/GLONASS System, : Four Character ID OHIZ, is operating : in O'Higgins since 09-FEB-2001. : Because of the expansion and of : construction works in the Chilenean : Antarctic Base we had to move the : antenna for the GPS Permanent Tracking : Station OHIG to another new pillar K6 : in our O'Higgins Observatory. : The four character ID for the new : antenna-site is OHI2. : For collocation we observed from : 14-FEB-2002 18:30 UT until : 20-FEB-2002 02:00 UT with two : AOA SNR-8000 ACT at OHIG and OHI2, : and also with the Ashtech Z-18 OHIZ. : 14-FEB-2002 18:30 UT OHI2 installed. : 16-FEB-2002 18:30 UT DOME removed in OHIG. : 19-FEB-2002 20:00 UT DOME installed in : OHI2. : 20-FEB-2002 02:00 UT OHIG removed. 2.
