DUBO Site Information Form International GPS Service for Geodynamics 0. Form Prepared by (full name) : Michael Schmidt Date Prepared : 29-SEP-1999 Report Type : UPDATE Prepared Using : 1. Site Identification of the GPS Monument Site Name : Lac du Bonnet Four Character ID : DUBO Monument Inscription : 924000 IERS DOMES Number : 40137M001 CDP Number : Date Installed : 18-OCT-1996 16:00 UT Geologic Characteristic : BEDROCK Bedrock Type : GRANITE 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 : 26-NOV-97: : ******************************************** : 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 concrete pier The concrete pier is anchored : to exposed bedrock using steel re-enforcement : bars. 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. The : antenna and choke ring asembly are protected : by a dome. 2.
