Corrections do Geodetic Coordinates in Japan

Abstract

The corrections to the geodetic coordinate system in Japan based on Bessel ellipsoid as the reference are derived by using laser ranging data to satellites obtained at the Dodaira Station of the Tokyo Astronomical. Observatory. Their values in meters are;dX=-153.96±0.83, dY=493.42±1.32, dZ=691.31±2.22in the geocentric rectangular coordinates and correspond to;dψ=11″827, dλ= -10″.894, N=41.5, where N is the geoid height in meters above the IAU 1976 ellipsoid.
