Abstract提出一种基于坐标系转换与QTM编码的天球面探测覆盖栅格化分析方法,并对其计算精度和效率进行了实验分析,相比传统算法和经纬网格编码方法,该方法具有明显的效率和精度优势,能够满足以天球面为探测目标的空间科学卫星有效载荷探测覆盖分析和任务规划的需要.
Other AbstractIn sky coverage analysis, we present an efficient algorithm based on a coordinate transformation method to calculate the points on the boundary of detection field. In this method, the complexity of coordinates transformation is reduced by building a new Celestial Coordinates. Based on this algorithm, QTM, a coding method that has many advantages can be used to manage the data calculated. The main contents of this topic include: to build the quantitative calculation model for sky coverage; to establish the rasterized expression method of sky coverage analysis results; and to verify the method, analyse the accuracy of the method, compare the efficiency with the attitude-matrix transformation method and analytical method.
