Role of Neutral Atmospheric Dynamics in Cusp Density and Ionospheric Patch Formation.

摘要

Our modern technology-based society relies on satellite communications. Consequently more and more satellites are sent into orbit by an increasing number of countries for both commercial and military purposes. The cost of each satellite can be a few hundred million dollars, and the information that they deliver can be commercially valuable and sensitive. This increases the pressure on high quality orbit determination, which requires reliable models of the behaviour of the upper atmosphere. The models must be based on observations and realistic physical mechanisms.
