Site Identification of the GNSS Monument Site Name : Dominion Radio Astrophysical Observatory Four Character ID : DRAO Monument Inscription : 887006 IERS DOMES Number : 40105M002 CDP Number : Monument Description : PILLAR/BRASS PLATE Height of the Monument : 1.5m Monument Foundation : STEEL RODS IN BEDROCK Foundation Depth : 0.75m Marker Description : BRASS PLATE; FORCED CENTER STAINLESS STEEL : BOLT Date Installed : 1991-02-27 Geologic Characteristic : BEDROCK Bedrock Type : METAMORPHIC / CONGLOMORATE Bedrock Condition : WEATHERED Fracture Spacing : 10-50 cm Fault zones nearby : NO Distance/activity : Additional Information : This station is part of the Western Canada : Deformation Array (WCDA) as well as the : Canadian Active Control System (CACS). : ******************************************* : The GPS reference mark consists of a brass : plate with a forced centered stainless steel : bolt. The brass plate is embedded on top of : a 1.5 metre high concrete pier, 40 cm in : diameter. The concrete pier is anchored to : exposed bedrock using steel re-enforcement : bars to a depth of 0.75 m. The antenna is : attached to the brass forced centered plate : via a 10 cm high anodized aluminum base. : This base provides a constant height : above the brass plate and also permits : the antenna to be referenced to north. : ** File Audited as of 03-APR-2002 2.
