Geophysical researches with the orbits of the first satellites
@article{Kinghele1983GeophysicalRW, title={Geophysical researches with the orbits of the first satellites}, author={D. G. King-hele}, journal={Geophysical Journal International}, year={1983}, volume={74}, pages={7-23} }
Summary.
This paper offers a partial view of the results of analysing the orbits of the first satellites, particularly Sputniks 1 and 2. The topics discussed include the zonal harmonics in the Earth's gravitational field and three features of the upper atmosphere - the air density and its variations; the scale height and temperature; and the zonal winds. The view presented is ‘partial’ in two senses: (a) because it is far from complete, and (b) because it has a personal bias.

Satellite orbital precessions caused by the first odd zonal J3 multipole of a non-spherical body arbitrarily oriented in space
- Physics

An astronomical body of mass M and radius R which is non-spherically symmetric generates a free space potential U which can be expanded in multipoles. As such, the trajectory of a test particle…
Satellite Orbital Precessions Caused by the Octupolar Mass Moment of a Non-Spherical Body Arbitrarily Oriented in Space
