More Information
Summary:The invention relates to a device for maintaining the attitude of a carrier, the device comprising three primary gyroscopes (1, 2, 3) that are arranged to measure primary speeds of rotation (Rbc) of acarrier about three primary axes, a secondary gyroscope (4) that is arranged to measure a secondary speed of rotation (Rhp) of the carrier about a secondary axis that is different from each of the primary axes, a video camera (5) having an optical axis that is different from each of the primary axes, and a data processing module (6) that is configured to estimate scale-factor and drift errors that corrupt the primary speeds of rotation (Rbc) using data issued from the secondary speed of rotation (Rhp) and images acquired by the video camera (5), and to correct the primary speeds of rotation with said estimated errors. 本发明涉及种用于维持运载器的姿态的装置，所述装置包括：三个主陀螺仪(1、2、3)，被设置为测量运载器围绕三个主轴的初级旋转速度(Rbc)；次级陀螺仪(4)，被设置为测量所述运载器围绕不同于所述主轴中的每个的次级轴的次级旋转速度(Rhp)；摄像机(5)，具有不同于所述主轴中的每个的光轴；数据处理模块(6)，配置为使用由所述次级旋转速度(Rhp)和所述摄像机(5)获取的图像产生的数据来估算损害所述
