However, the OS could not use these advantages to be a satisfactory solution model for big data because of the lack of horizontal scalability. The main task of OS file management is to serve system calls to other applications. So, the OS is a part of the solution rather the solution ...
1.1.2 无场外方位元素定标式(1)以滚动角 误差为例,OS 为真实成像光线,OS'为 带误差成像光线,ω为垂轨向成像角 (包含成像侧摆角,探元视场角等),Δω为滚动角 误差,H 为卫星高度. 则可得垂轨向定位误差ΔY为 Y=H [tan(ω) -tan(ω+Δω) ] (3) 图 1 轨道坐标空间滚动角误差对几何定位的影响...
