Abstract

This paper presents developments to a set of high fidelity spacecraft surface force models. These models address the problem of errors in orbital prediction and orbital determination due to in-modeled and under-modeled surface forces on spacecraft. These models have been validated individually but in this paper the most recently developed models are applied together to give an insight into how they effect a spacecraft in orbit. A significant reduction in error between the predicted orbit and tracking data is shown when all the models are implemented.
