BETR Site Information Form GPS/GLONASS Campaign IGEX98 0. Form Prepared by (full name) : Doug Hardman Date Prepared : 3-Nov-1998 Report Type : NEW Prepared Using : MS Word 1. Site Identification of the GPS/GLONASS Monument Site Name : Bellevue 157T Four Character ID : betr Monument Inscription : Nil IERS DOMES Number : 50142M002 CDP Number : Monument Description : Stainless steel plate located on the third floor rooftop level, Department Of Land Administration Building. Date Installed : 24-OCT-1998 09:00 UT) Geologic Characteristic : Deep sands to depths of 500 metres, some isolated clay and limestone deposits encountered in nearby bore geological profiles. Bedrock Type : Unknown Bedrock Condition : Unknown Fracture Spacing : Unknown Notes : There are 10 boresites within the general region of Bellevue 157 T, established for aquifer monitoring purposes and for which geological drilling profile records are available. The geological profiles from 0m (ground level) to 500m depth reveal deep sands intersecting some thin bands of clay and some minor limestone bands at depths ranging from about 30m down through to 500m. There is no (readily available) information at depths below 500m, nor any information on the underlying bedrock. Additional Information : Nil 2.

The GG24 unit is located nearby, some 14 metres away, on BEL 157. Bellevue 157T is a stainless steel pillar plate and 16 mm (5/8") whitworth threaded bolt, secured permanently to the top of the concrete security wall surrounding the rooftop. Both marks are contained within the locked, security monitored DOLA building, North Node. There is good all round visibility to the sky above an elevation of 15o from the horizon. Power is provided to the rooftop site. 3.
