Site Location Information City or Town : Brest State or Province : Finistère Country : France Tectonic Plate : Europe Approximate Position X coordinate (m) : 4228878.801 (m) Y coordinate (m) : -333093.202 (m) Z coordinate (m) : 4747180.249 (m) Latitude (deg) : ( dd.dddd N/S) Longitude (deg) : (ddd.dddd E/W) Elevation (m) : (m) Additional Information : Coordonnées rapportées au RGF93 3. Receiver Information 3.1 Receiver Type : GG24 (Martec) Satellite System : GPS+GLONASS Serial Number : S/N M0627-24-010 Firmware Version : P/N MTCP006A Date Installed : (dd-MMM-yyyy hh:mm UT) Date Removed : (dd-MMM-yyyy hh:mm UT) Additional Information : (multiple lines) 4. Antenna Information 4.1 Antenna Type : GG ANT L1 (Ashtech) Serial Number : P/N 701023 (B) Antenna Height (m) : 1.349 (m) Antenna Reference Point : ARP Degree Offset from North : 0 Antenna Radome Type : Date Installed : (dd-MMM-yyyy hh:mm UT) Date Removed : (dd-MMM-yyyy hh:mm UT) Additional Information : Caracteristics were given by ASHTECH (Linda Malcom-Lim). She wrote caracteristics of P/N 701023 antenna are the same of 700699 antenna. So radius is 0.109 m where slant height is measured and vertical distance from the antenna ground plane (level where slant height is measured) to the antenna phase center is 0.005 m. So antenna height = sqrt (1.359² - 0.109²) - 0.005 = 1.349 m. Information was given the 20th Nov 1998. 5.
