福建省-其他测绘地理信息服务-全球重点关注卫星位置信息

即目前获取的卫星的位置和预测信息表，如果卫星不增加这个记录基本就不增加，但也会有一些少量变化。卫星与（不同日期）位置信息是一对多关系。
此类数据主要是预测卫星的位置等信息，用于预测和计算卫星的拍摄范围等卫星轨迹信息

This refers to the currently collected satellite position and prediction information table. The records will basically remain unchanged unless new satellites are added, though minor fluctuations may still occur occasionally. There is a one-to-many relationship between satellites and their position information across different dates. This type of data is primarily used to predict satellite position and other relevant information, aiming to forecast and calculate satellite trajectory details such as their imaging coverage.
