Optimum Integration of Aircraft Navigation Systems

Abstract

A current problem in aircraft navigation is determining how to effect alow cost navigation system consistent with required mission operationswhich will render a high degree of accuracy and reliability. One wayto achieve this is through optimum integration of equipment,subsystems, and computer mechanizations. Consistent with this approach,the overall objectives of this paper are to show the advantages of anoptimally integrated aircraft navigation system, and to illustrate howto effect a low cost navigation system with high accuracy performance.An integrated aircraft navigation system employing a Kalman optimumestimation filter is configured and analyzed in detail. The results ofthe analysis clearly indicate how to achieve high accuracy performanceusing low cost subsystems; namely, via optimum systems integration.
