 AJ1910.ITRF positions are available for this station.
 AJ1910.The horizontal coordinates were established by GPS observations
 AJ1910.and adjusted by the National Geodetic Survey in February 2003.
 AJ1910.This is a SPECIAL STATUS position.  See SPECIAL STATUS under the
 AJ1910.DATUM ITEM on the data sheet items page.
 AJ1910.The horizontal coordinates are valid at the epoch date displayed above.
 AJ1910.The epoch date for horizontal control is a decimal equivalence
 AJ1910.of Year/Month/Day.
 AJ1910
 AJ1910.The orthometric height was determined by GPS observations and a
 AJ1910.high-resolution geoid model.
 AJ1910
 AJ1910.The X, Y, and Z were computed from the position and the ellipsoidal ht.
 AJ1910
 AJ1910.The Laplace correction was computed from DEFLEC99 derived deflections.
 AJ1910
 AJ1910.The ellipsoidal height was determined by GPS observations
 AJ1910.and is referenced to NAD 83.
 AJ1910
 AJ1910.The geoid height was determined by GEOID99.
