Comparison of Three Vertical Channel Designs for an Integrated GPS/Inertial Navigation System.

Abstract

The Integrated GPS/Inertial (IGI) Simulator is utilized to explore design issues associated with the vertical channel of a GPS/baro/inertial 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 baro/inertial 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.
