摘要
Ｊａｃｃｈｉａ１９７７大气模型（简称Ｊ７７）发表后，Ｊａｃｃｈｉａ本人对模型进行了两次重大修订。这两个修订都是关于地磁活动引起的大气密度的变化，为了比较分析修订后模型的改进情况，本文作者更新了Ｊ７７模型的软件，对每一步修订进行了详细的数值试验。并将其应用于高度为８００公里ＥＲＳ－１卫星的轨道计算，结果表明：修订后的Ｊ７７模型比其它大气模型在测轨精度上有明显改善。
Having thoroughly investigated two revisions of J77 model in the atmospheric density variations with the geomagnetic activity made by Jaccliia a few months after J77 model was published in 1977, the author renewed the version of J77 program with them. Every change mader to J77 has been tested out with the numerical method in detail. The new version of J77 is found to be obviously advantageous to the precision orbit determination of ERS-1, which is at the height of 800km, compared with other atmospheric models.
