The determination of the gas-surface interaction from satellite orbit analysis as applied to ANS-1 (1975-70A)
Abstract
This paper considers the technique of orbital analysis as a means of determining the ill-defined gas-surface interaction between spacecraft and atmospheric molecules in Low Earth Orbit (LEO). The problem of representing the aerodynamics of complex vehicles in LEO is considered. The theory required to represent the relationship between the changes in the spacecraft trajectory and the gas-surface interaction is developed. This theory is then applied to the orbital data of ANS-1 (1975-70A) and the results of the analysis compared with those of previous investigators.
