Abstract
A model describing the continuous portion of a comet’s outgassing pressure field is presented. Applications of the model to spacecraft navigation are discussed, noting that such models are similar to a gravity field representation and, hence, can be estimated with radio metric tracking of a spacecraft. The model is fit to numerically generated outgassing fields for the comets Tempel-1 and Wirtanen. The parameter coefficients for these fits are presented along with comparisons showing that the analytical form fits the numerically computed fields well.
