基于极轨卫星对地观测覆盖模型算法研究

Earth Observation Coverage Model Algorithm Based on Polar-orbiting Satellite

极轨卫星由于其典型的轨道特征而受到业界的青睐,其数量占卫星总量的绝大多数。单位时间传感器对地覆盖作为制约卫星数据运用的重要因素之一,其覆盖模型的优劣直接影响覆盖精度和运算速度。本文针对极轨卫星提出了一种平面矩形覆盖模型,它在保证覆盖精度的基础上大大简化了计算工作量。

Because of polar-orbiting satellites＇ typical characteristics of the orbit, it is becoming the industry＇s favor. Their number is the vast majority of the total satellite.As one of the important factors restricting the use of satellite data, sensor coverage model will have a direct racy and speed of operation. This paper presents a model of planar rectangular precision of coverage, but also simplifies the amount of calculation.
