DTM94 Atmosphere Model and Its Application

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.
