PM1 5-min Spacecraft attitude data from GBAD - NRT

PM1ATTNR is the Aqua Near Real Time (NRT) daily spacecraft attitude 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:PM1ATTNR_NRT.Ayyyyddd.hhmm.vvv where from left to right: PM1 = PM1 (Aqua); ATT = spacecraft attitude; N = Native format; R = Refined; A = Acquisition; yyyy = data year, ddd = Julian data day, hh = data hour, mm = data minute; vvv = Version ID.

PM1ATTNR系Aqua近实时（NRT）每日航天器姿态数据文件，采用原生格式。该数据属于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，已转换为ECS SDP工具包支持的内部标准。此类数据通常用于确定地球遥感观测的地理位置。文件名格式如下：PM1ATTNR_NRT.Ayyyyddd.hhmm.vvv，其中自左向右分别为：PM1 = PM1（Aqua）；ATT = 航天器姿态；N = 原生格式；R = 精炼；A = 获取；yyyy = 数据年份，ddd = 约化数据日，hh = 数据小时，mm = 数据分钟；vvv = 版本标识。
