Form Prepared by (full name): Miranda Chin Date : August 20, 1993 Report type : NEW (NEW or UPDATE) 1. Site Identification of the GPS monument Site Name : Richmond 4 char ID : RCM4 Monument Inscription : Richmond 1993 IERS DOMES Number : 40499 M005 CDP Number : not assigned Date : August 1993 Additional information : CIGNET - Permanent GPS Tracking Network 2. Site Location City : Perrine, Florida Country : U.S.A. Tectonic Plate : North American Additional information : The monument is located at the U.S. Coast Guard ground which is adjacent to the Naval Observatory Timing Station. 3. GPS Receiver Type : Rogue SNR-8000 (Turbo Rogue) Serial Number : T 125 Firmware Version : 2.8 Date : August 18, 1993 4. GPS Antenna Type : Dorne Margolin T Serial Number : 104 Date : August 18, 1993 Vertical Antenna Height: 0.0614m Antenna Reference Point: BPA (Bottom of the Pre-Amp) Date : August 18, 1993 5. Local Site Ties Monument CDP DOMES Components Accuracy Date Name Number Number dX dY dZ mm yy-mm-dd .................. ....... .......... .......... ........ .......... .. .. .. .. .. .. Richmond VLBI 7219 40499S001 15.2112 -68.3991 -123.8343 93 08 18 Richmond RCM2/MSLR 7295 40499M002 76.0896 -69.3290 -168.0481 93 08 18 Note: The differential coordinates are from the RCM4 GPS monument to the VLBI 7219 reference point and the RCM2 GPS monument. These numbers are derived from a GPS survey conducted in August, 1993 with three Rogue receivers. The repeatabilities are within 2mm. The antenna vertical height (from the monument to the bottom of the chokering) at RCM2 is 0.094m. Differential coordinates from the GPS monument to the reference and other monuments. The components are parallel to the XYZ-axes of the global geocentric reference system ITRF (WGS-84). "Accuracy" is estimated accuracy of local survey (millimeters). 6.
