Antenna Reference Point (ARP): Site Log
ITRF00 POSITION (EPOCH 1997.0)
Computed by NGS using OPUS on 04/10/02 w/ 10 days of data 01/27-02/05/02
X = 1516052.053 m latitude = 41 29 20.18875 N
Y = -4538296.762 m longitude = 71 31 39.78108 W
Z = 4203281.740 m ellipsoid height = 44.438 m
ITRF00 VELOCITY
Predicted with HTDP
VX = -0.01698 m/yr northward = 0.00569 m/yr
VY = -0.00186 m/yr eastward = -0.01669 m/yr
VZ = 0.00441 m/yr upward = 0.00021 m/yr
NAD_83 POSITION (EPOCH 2002.0)
Computed by NGS using OPUS on 04/10/02 w/ 10 days of data 01/27-02/05/02

NAD_83 VELOCITY
Predicted with HTDP
VX = 0.00000 m/yr northward = 0.00000 m/yr
VY = 0.00000 m/yr eastward = 0.00000 m/yr
VZ = 0.00000 m/yr upward = 0.00000 m/yr
L1 Phase Center of the current GPS antenna:
TRIMBLE CHOKE RING ANTENNA
Antenna Code = TRM29659.00
The L2 phase center is 0.0182 m above the L1 phase center
ITRF00 POSITION (EPOCH 1997.0)
Computed by NGS using OPUS on 04/10/02 w/ 10 days of data 01/27-02/05/02
X = 1516052.079 m latitude = 41 29 20.18875 N
Y = -4538296.840 m longitude = 71 31 39.78108 W
Z = 4203281.813 m ellipsoid height = 44.548 m
The ITRF00 VELOCITY of the L1 PC is the same as that for the ARP.
