Geoscience Australia's predictive schedules for public good satellites over Australia

BackgroundEvery day more than a dozen foreign-operated, public-good, non-commercial, medium to low resolution satellites fly over Australia and its territories. They cross the continent several times a day and their sensors capture images of the landand coastal waters.Satellite overpass schedules for each spacecraft are predictable and can be calculated with a degree of accuracy. The Daily SatPaths provides information on which satellite sensors have and will potentially acquire data over Australia during a given date and time interval. It is important to note that actual acquisition schedules may differ from those presented in Daily SatPaths due the operational limitations of the satellite.

背景：每日有十余颗由境外运营、面向公共利益的非商业性中低分辨率卫星飞越澳大利亚及其所辖领地。这些卫星每日多次横穿澳洲大陆，其搭载的传感器可捕获陆地与近岸海域的影像。每颗卫星的过境日程均可预测，且可达到一定精度进行计算。《Daily SatPaths》数据集提供了指定日期与时间区间内，已在澳大利亚上空获取数据，或有望在此获取数据的卫星传感器相关信息。需特别说明的是，受卫星运行限制，实际数据获取日程可能与《Daily SatPaths》中展示的内容存在差异。
