The Earth's atmosphere is often portrayed as a thin and finite blanket covering our planet, separate from the emptiness of outer space. In reality, the transition is gradual and a tiny fraction of the atmophere gases is still present at the altitude of low orbiting satellites. The very high velocities of these satellites ensure that their orbital motion can still be considerably affected by air density and wind. This influence can be measured using accelerometers and satellite tracking techniques. The opening chapters of this thesis provide an excellent introduction to the various...

This text covers advances in the algorithms used for processing satellite accelerometry and Two-Line Element (TLE) orbit data in the collection of data on atmosphere and wind. Coverage includes an extensive analysis of the resulting density and wind products.
