An airborne Glideslope Computation/Gust Detection System was developed for supporting flight tests of NAL’s Variable Stability and Response Airplane (VSRA). The system includes a set of Kalman filters to estimate position and inertial velocity and utilizes signals from DME, the pressure altimeter, and accelerometers and gyros. Glideslope and localizer deviations from a preselected nominal flight path having an arbitrarily assigned glideslope angle, are computed and transmitted to ADI and HSI instead of the standard ILS signals. Gust components as differences of inertial and air speeds are also estimated. Based upon flight test data, estimated horizontal inertial speed is compared with that obtained from Doppler Radar, and validity and accuracy of gust estimation are verified by state reconstruction techniques.
