Abstract
A GPS-based pitol-static calibration system uses global output-error optimization. High data rate measurements of static and total pressure, ambient air conditions, and GPS-based ground speed measurements are used to compute pitot-static pressure errors over a range of airspeed. System identification methods rapidly compute optimal pressure error models with defined confidence intervals.
Claims8
A method for determining pitot-static tube pressure sensing error, comprising modeling said error as a continuous function of airspeed.
