资源简介：
PM1EPHND is the Aqua Near Real Time (NRT) daily spacecraft definitive ephemeris data file in native format. This is MODIS Ancillary Data. The data collection consists of PM1 Platform Attitude Data that has been preprocessed by ECS to an internal standard supported by the ECS SDP Toolkit. This data is typically used in determining the geolocation of earth remote sensing observations.The file name format is the following:
PM1EPHND_NRT.Ayyyyddd.hhmm.vvv
where from left to right:
PM1 = PM1 (Aqua);
EPH = Spacecraft Ephemeris;
N = Native format;
D = Definitive;
A = Acquisition;
yyyy = data year,
ddd = Julian data day,
hh = data hour,
mm = data minute;
vvv = Version ID.
PM1EPHND系Aqua近实时（NRT）每日航天器最终星历数据文件，采用原生格式。该数据集为MODIS辅助数据。数据收集包括经过ECS预处理的PM1平台姿态数据，该数据已根据ECS SDP工具包支持的内部标准进行处理。此类数据通常用于确定地球遥感观测的地理定位。文件名格式如下：
PM1EPHND_NRT.Ayyyyddd.hhmm.vvv
其中，从左至右分别为：
PM1 = PM1（Aqua）；
EPH = 航天器星历；
N = 原生格式；
D = 最终；
A = 获取；
yyyy = 数据年份；
ddd = 朱利安数据日；
hh = 数据小时；
mm = 数据分钟；
vvv = 版本标识。
