Abstract:

The Integrated GPSInertial IGI Simulator is utilized to explore design issues associated with the vertical channel of a GPSbaroinertial navigation system. The assumed navigation system includes a local-level wander azimuth inertial navigation system with associated barometric altimeter for stabilizing the vertical channel, a Global Positioning System GPS pseudo range and range-rate receiver, and a navigation computer hosting a Kalman filter to integrate the baroinertial and GPS data. The simulated flight path is an F-4 high dynamic tactical mission profile. Of particular interest in evaluating vertical channel performance is a seven minute period during which jamming prevents the use of GPS measurements. Three Kalman filter designs are evaluated.
