1) star position angle
星位角
1.
Through the solution, the star position angle can be found with so - called "star distance" (Short for the spherical distance between two stars)determined So as to have the fix solved.
用解球面三角形的方法,通过两天体的球面距离,求得星位角,从而求得船位的经纬度。
2) satellite aximuth
卫星方位角
3) satellite azimuth angle and elevation angle
卫星方位角和仰角
5) elevation angle of star
星光仰角
1.
An autonomous navigation scheme is designed by using the star sensor and horizontal instrument to observe the elevation angle of star.
利用星敏感器和地平仪测量"星光仰角",进行自主导航方案设计。
2.
Using UD decomposing to modify EKF Particle filter was imported into the navigation scheme based on the measurement of elevation angle of star.
用UD分解改进EKF粒子滤波算法,并将其应用于基于星光仰角测量的探测器自主导航方案。
6) star angular distance
星对角距
1.
This algorithm directly uses star angular distance as matching feature.
该算法直接以星对角距为匹配特征,先确定影像中亮星为中心星,并以此星与相邻星像点构建辐射状星图,统计所有满足星对角距匹配条件的导航星出现次数,次数最多的即为中心星所对应的导航星。
2.
And then star angular distances are directly stored according to their length in- creasing.
然后按照星对角距的大小升序排列,直接存储星对角距,并通过设置星对角距状态标识,完成星对角距的快速匹配搜索。
补充资料：星位
1.星宿在天上的地位。旧时认为星位决定人们的贫富尊卑。 2.指星辰在天体的位置。
