摘要
简述了DTM94 大气模型, 并以其旧版本DTM78 为对照进行了初步考察和分析, 其中给出了两种模型的大气密度随地磁指数kp 和太阳辐射流量(Solar Radio Flux) 变化的情况, 并对20d ( 天) 弧长Ajisai 卫星的全球SLR观测资料进行处理, 结果表明DTN94 对近地卫星Ajisai 的精密定轨是十分有利的。
DTM94 atmosphere model is briefly described in the text,and in contrast with DTM78 preliminary consideration and analyses are carried out.Therein,the Authors present the variation of atmospheric density with geomagnetic indices k p and solar radio flux,respectively.20 day interval global SLR data from satellite Ajisai was reduced.It shows that atmosphere model DTM94 is beneficial to the precise orbit determination of satellite Ajisai.
