| 摘 要： | 针对资源一号02B卫星,建立影像的严密成像几何模型,研究系统误差的补偿方法.实验采用GPS和AOCS的观测数据,将资源一号02B高分辨率影像的定位精度从860个像素(RMS)提高到216个像素(RMS).分析误差产生的根源,求解俯仰、滚动2个旋转角度和俯仰、滚动、偏航3个旋转角度时,均明显提高了影像的几何定位精度,对于沿轨道方向的误差加入偏航角校正优于不加偏航角校正. |

| Abstract: | In this paper,for CBRS02B,the rigorous sensor model of images was established,the system error was analyzed and the compensation methods were derived.Using the AOCS and GPS observational data in the experiment,the positioning accuracy of the CBRS02B high-resolution images was improved from 860 pixels(RMS) to 216 pixels(RMS).And analysis and comparison of error was done from the source in the two cases which included the solution of pitching angle,rolling angle and the pitching angle,rolling angle,yawing ang... |
