Aircraft, has attitude measurement device including optical sensor that captures images of stars, where attitude measurement device measures attitude of aircraft at both day and night from images taken by sensor

摘要

The aircraft (1) has an attitude measurement device (2) including an optical sensor (3) e.g. charge coupled device (CCD) sensor, having a detection surface provided with pixels (6) greater than 10 megapixels, where a field of view of the sensor is defined by a field angle of view higher than 10 degrees. The sensor captures images of stars (7), where the device measures the attitude of the aircraft at both day and night from the images taken by the sensor. The device includes a Kalman filter (12) to filter light of wavelength lower than 550 nanometer moving towards the detection surface. An independent claim is also included for a method for measuring an attitude of an aircraft.
