A Study on the Errors in the Free-Gyro Positioning System (Ⅰ)

Abstract

This paper is to develop the position error equation of in the free-gyro positioning system by using two free gyros. First, the determination of a position is analyzed on the ellipsoid of the Earth and the type of the errors is defined Finally the position error equation is introduced and developed, based on the definition of the type of errors which may be involved in the FPS.

Key Words: Free gyro;Zenith angle;Position error equation;FPS;Sensor error;Danger zone;Error of position
