This invention relates generally to the measurement of geodetic quantities and more particularly to a method of simultaneously measuring orthometric and geometric heights. Knowledge of the vertical deflection of the gravity vector has great utility in various inertial navigation andor geodetic applications. Conventional procedures to determine the two dimensional deflection of the gravity vector require the use of a theodolite for stellar observations and clear night time weather conditions. Therefore, this procedure is sensitive to environmental conditions.
