利用下载的goce原始数据，计算得出含有时间/经纬度/重力梯度格式的程序-Use downloaded goce raw data, calculated with the time/latitude/gravity gradient program formats

satellite orbital calculation may it be useful.-satellite orbital calculation may it be useful.

对ESA网站下载的GOCElevel_1b的EGG_NOM_1b数据进行提取，得到重力梯度观测值与四元数数据。(The GOCElevel_1b data of EGG_NOM_1b downloaded from the ESA web site are extracted, and gravity gradient observations and four yuan data are obtained.)
