HOLB Site Information Form International GPS Service for Geodynamics 0. Form Prepared by (full name) : Michael Schmidt Date Prepared : 02-JUL-1999 Report Type : UPDATE Prepared Using : 1. Site Identification of the GPS Monument Site Name : Holberg Four Character ID : HOLB Monument Inscription : 927005 IERS DOMES Number : 40130M001 CDP Number : Date Installed : 24-JUL-1992 Geologic Characteristic : BEDROCK Bedrock Type : IGNEOUS/METAMORPHIC Bedrock Condition : WEATHERED Fracture Spacing : over 200 cm Notes : Additional Information : This station is part of the Western Canada : Deformation Array (WCDA) as well as the Canadian : Active Control System (CACS). The following : information is current as of 03-DEC-97: : ************************************************ : The GPS reference mark consists of a brass plate : with a forced centred stainless steel bolt. The : brass plate is embedded on top of a 1.0 metre : high concrete pier, 60 cm in diameter. The : concrete pier is anchored to exposed bedrock : using steel re-enforcement bars to a depth of : 0.5 m. The antenna is attached to the brass : forced centred 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. The : antenna and choke ring asembly are protected by : an acrylic dome. The dome was installed using : an aluminum flange ring attached to the choke : ring. The flange ring extends the radius of the : ground plane by 2.5 cm. 2.
