Form Prepared by (full name): Carme Parareda Geodetic Department (Institut Cartografic de Catalunya) Date : 27 March 1996 Report type : UPDATE (NEW or UPDATE) 1. Site Identification of the GPS monument Site Name : Ebre 4 char ID : EBRE Monument Inscription : IERS DOMES Number : 13410M001 CDP Number : Date : March 1992 Additional information : full operating capability since April 1994 though we took part in several observation campaigns previously. a former Sation Report had been sent to the IGS for the EPOCH'92 campaign. the monument is a 4.20m concrete pillar. the antenna is oriented to the True North. 2. Site Location City : Roquetes Country : Spain Tectonic Plate : Iberic plate - Eurasiatic plate Additional information : the site is placed in an astronomic observatory, Observatori de l'Ebre 3. GPS Receiver Type : TRIMBLE 4000SSE Serial Number : 3312A02805 Firmware Version : 6.01 Date : 23 May 1994 (use type names from attached list) 4. GPS Antenna Type : 4000ST L1/L2 GEOD Serial Number : 00080026539 Date : 4 Feb 1994 Vertical Antenna Height: 0.054m Antenna Reference Point: Bottom of preamplifier Date : 4 Feb 1994 Type : MicroPulse L1/L2 Serial Number : 90LL12300 Date : 28 Feb 1995 10:57 UTC to present Vertical Antenna Height: 0.054m Antenna Reference Point: Bottom of preamplifier Date : 28 Feb 1995 10:57 UTC to present The antenna height is measured from the GPS Monument Reference Point to the antenna reference point (ARP) as shown in the graphic (10). 5. Local Site Ties Monument CDP DOMES Components Accuracy Date Name Number Number dX dY dZ mm yy-mm-dd SALOU (EUREF 076) -18176.157 56811.670 20034.209 82 94-03-18 Obs. de l'Ebre 47.618 133.352 -61.570 .1 92-10-23 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.
