Atmospheric drag on the satellite
Journal of Geophysical Research, 1957The drag exerted on the satellite in its orbit arises partly from collisions with neutral air particles and partly from losses associated with the passage of a charged sphere through an ionized medium. It is found that the charged and neutral effects are comparable under the atmospheric conditions expected at an orbital altitude of 300 miles.

A scientific earth satellite that is guided in a drag-free orbit by a shielded, free-falling proof mass has been proposed by a number of investigators. This paper examines the feasibility and some of the applications of this scheme. The control and guidance system is analyzed with respect to system performance and gas usage requirements.

Abstract The drag of artificial earth satellites is reconsidered in the light of recent studies of gas-surface interactions and atmospheric composition. Between heights of 140 and 400 km at times of low solar activity, or heights of 140 and 600 km at times of high solar activity, the drag coefficient is almost independent of height, and at present ...

The average drag on the LAGEOS satellite appears to be well understood. It consists of three types of drag: Yarkovsky thermal, neutral particle, and charged particle. Yarkovsky thermal drag depends on the LAGEOS spin axis position. The spin axis in the decade since launch appears to have stayed near where the engineering telemetry data put it at apogee

Drag coefficients for tumbling satellites.
Journal of Spacecraft and Rockets, 1967Figure 3 shows how typical PLOT results are presented. For illustrative purposes, ROD is plotted as a function of normal countdown time, which is extended by the programmed hold. Gain in PLOT is plotted as a function of programmed hold-time; the gain is referenced to RCD for the normal countdown.
