AB3306.This is a reference station for the MOBILE POINT 1
AB3306.National Continuously Operating Reference Station (MOB1).
AB3306
AB3306.ITRF positions are available for this station.
AB3306.The horizontal coordinates were established by GPS observations
AB3306.and adjusted by the National Geodetic Survey in May 1996.
AB3306
AB3306.The orthometric height was determined by differential leveling
AB3306.and adjusted by the National Geodetic Survey in February 2001.
AB3306
AB3306.Photographs are available for this station.
AB3306
AB3306.The X, Y, and Z were computed from the position and the ellipsoidal ht.
AB3306
AB3306.The Laplace correction was computed from DEFLEC99 derived deflections.
AB3306
AB3306.The ellipsoidal height was determined by GPS observations
AB3306.and is referenced to NAD 83.
AB3306
AB3306.The geoid height was determined by GEOID99.
AB3306
AB3306.The dynamic height is computed by dividing the NAVD 88
AB3306.geopotential number by the normal gravity value computed on the
AB3306.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
AB3306.degrees latitude (g = 980.6199 gals.).
AB3306
AB3306.The modeled gravity was interpolated from observed gravity values.
