空間運(yùn)動(dòng)物體的一種三軸定向方法

這個(gè)系統(tǒng)利用重力加速度計(jì)與磁通門磁強(qiáng)計(jì)實(shí)現(xiàn)對(duì)三維空間物體的姿態(tài)測(cè)量, 并能以此為基準(zhǔn)實(shí)現(xiàn)物體空間移動(dòng)軌跡的檢測(cè)。在方向的測(cè)量中使用了3 個(gè)傳感器代替?zhèn)鹘y(tǒng)的單個(gè)傳感器測(cè)量, 以減小加速度計(jì)與磁通門計(jì)在與物體運(yùn)動(dòng)方向成較小角度時(shí)靈敏度的下降。通過(guò)實(shí)驗(yàn)得知這種方法是十分有效的。

Abstract : A system utilizing accelerometers and flux - gates to detect aerocraft attitude in space , therefore realizing the real - time measurement of moving path based on this information , is introduced in this paper , Instead of using one sensor to mea2 sure the direction , this system uses three perpendicularly mounted sensors to measure one direction so as to avoid the sensibility loss on small angle. Through experiment , this method is proved to be effective。
Key words : magnetic flux - gate ; direction sensing ; space locating
