Regression Analysis Technique for Air Data Sensor Calibration with an Inertial Navigation System

摘要

Error models for the calculation of air data sensor errors and of the wind using a pitot static system or a flight log for the true airspeed are described. Ground speed was based on an inertial navigation system. The different models were evaluated by regression analysis methods. Flight tests produce an estimated airspeed error of 3%. A comparison with external data from a weather bureau results in a mean difference of + or - 2 m/sec and the 2 chosen flight tests produce an air speed error of 5%.
