Today's aircraft commonly require expensive high quality inertial navigation equipment to provide accurate position and attitude information for navigation and flight control. By utilizing the Global Positioning System (GPS), which will be the preeminent navigation system of the 1990's, in conjunction with a strapdown Attitude and Heading Reference System (AHRS), equivalent performance can be obtained at substantially reduced cost. A mixed GPS/AHRS system combines the excellent long term navigation performance of GPS with the good short term performance of AHRS under high dynamic conditions. This paper will discuss alternative implementations of a mixed GPS/AHRS system. Factors considered in the designs described are performance requirements, system reliability and overall system cost. Simulations are presented to demonstrate the system performance under different flight scenarios.
