Algebraic approach to the bearings-only estimation equations

Two examples of filter equations are derived for which the measurement equation yields the directional cosine of the target relative to a known axis. This redefinition of the measurement equation leads to filter equations which are nonlinear algebraic rather than transcendental. Furthermore, these e...

Zusammenfassung:Two examples of filter equations are derived for which the measurement equation yields the directional cosine of the target relative to a known axis. This redefinition of the measurement equation leads to filter equations which are nonlinear algebraic rather than transcendental. Furthermore, these equations are inherently three-dimensional. It is noted that inclusion of multiple measurement axes is straightforward. (L.M.)
