 AF9554.ITRF positions are available for this station.
 AF9554.The coordinates were established by GPS observations
 AF9554.and adjusted by the National Geodetic Survey in March 2002.
 AF9554.The coordinates are valid at the epoch date displayed above.
 AF9554.The epoch date for horizontal control is a decimal equivalence
 AF9554.of Year/Month/Day.
 AF9554
 AF9554.The orthometric height was determined by GPS observations and a
 AF9554.high-resolution geoid model.
 AF9554
 AF9554.The PID for the CORS L1 Phase Center is AJ7893.
 AF9554
 AF9554.The XYZ, and position/ellipsoidal ht. are equivalent.
 AF9554
 AF9554.The ellipsoidal height was determined by GPS observations
 AF9554.and is referenced to NAD 83.
 AF9554
 AF9554.The geoid height was determined by GEOID99.
