摘要
在现代卫星摄影测量中,由多颗小卫星组成的卫星编队具有比单颗卫星更优越的性能,能提供更高的空间分辨率和时间分辨率。通过对绕飞编队特性的研究,提出了一种适于摄影测量的卫星绕飞编队构形。该卫星编队具有空间构形不变、覆盖范围大,图像比例尺一致等优点。对地三维定位仿真的实验结果表明:基于卫星编队拍摄的具有航向和旁向充分重叠的区域网图像,在摄像机光心坐标精确确定的条件下,利用光束法区域网平差就可以确定地面目标点坐标,即用空中控制完全代替地面控制是可行的。
In modern satellite photogrammetry, clusters of low-performance satellite flying in formation may proviee enhanced performance over single high-performance satellite. This is especially true for photogrammetry based on the satellite formation where stereographic imaging may provide higher resolution data. According to the study of the performance of the satellite flying-around formation, a formation suit for photogrammetry is proposed. The formation that proposed in the paper has many such merits as the const space structure, high coverage performance and almost identical image scale. The simulation results of ground point localization show the feasibility of using aerial control instead of ground control when camera optical center is known.
