Abstract
To the problems oftemperature drift inMEMS pressure sensor, inaccuracy of pressure-altitude model and noises in height measurement, the temperature compensation, modeling and fusion with inertial navigation system in altitude measurement are studied:Firstly, the pressure error due to temperature is analyzedand compensated. Secondly,numerical integration is applied in altitude computation, which is compared withstandard atmosphere altitude model. Final y, information fusion based on INS and pressure sensoris realized byAdaptive Filter. Experiment shows that the height and vertical velocity measurement with this method is accurate, swift and free of error accumulation.关键词
