TIXI Site Information Form International GPS Service for Geodynamics 0. Form Prepared by (full name) : Grigory Steblov Date Prepared : 14-FEB-2000 Report Type : UPDATE Prepared Using : 1. Site Identification of the GPS Monument Site Name : Seismic Station Tixi Four Character ID : TIXI Monument Inscription : IERS DOMES Number : 12360M001 CDP Number : (XXXX) Date Installed : 08-OCT-1998 Geologic Characteristic : Verkhoyansk fold-and-thrust belt Bedrock Type : Thick siltstone series Bedrock Condition : Jointed Fracture Spacing : Over 200 cm Notes : Tixi is about 100 km to the east of the : margin of Siberian platform. Additional Information : This station is part of NEDA: Northern Eurasia : Deformation Array created and run by : RUSEG: Russia/US Experiment on Geodynamics : by GPS Technology. NEDA operational control : is provided by RDAAC: Regional GPS Data : Acquistion/Analysis Center (Moscow). RDAAC : is also IGS Operational Center for NEDA. : RUSEG is a collaborative project of Lamont- : Doherty Earth Observatory and Russian Academy : of Sciences supported through the IRIS : Consortium. :******************************************** : The GPS reference mark consists of : 5/8-11" diameter, vertical rod of the : stainless steel. : The rod is glued into the flat top of the 2-m : high rectangular construction made of reinforced : concrete on the roof of the apartments : building. The 20-cm thick roof is also made : of reinforced concrete. : Seismic station computer room is in this : building. The GPS receiver is located in that : room and it is connected to antenna with : a 30-m cable protected with a metal conduit. : The 4-floors building has 30-cm thick brick : walls without cracks. It is supported by : 90 stilts driven into the permafrost to : a depth of 10 m, about 8 m below the depth : of maximum melting in summer. : Vertical datum: punched center on top surface : of the rod. : The antenna is attached to the rod with : UNAVCO compact leveling mount. The antenna : and the choke-ring assembly are protected : with the JPL hemispherical radome. 2.
