W LON:        111 50 36.11989
EL HGT:            1368.185

Compute L1PC as ARP + L1Offset:
EL HGT:            1368.071 m  + 0.114 = 1368.185


Note: the station has the coordinates for the L1 Phase center entered 
as the reference location, and broadcasts the L1PC with a null antenna definition.
The L1Offset for the antenna is 0.11413 meters.
