Method of Simultaneously Measuring Orthometric and Geometric Heights.

Abstract

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 and/or 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.
