Problems in Estimation Theory with Applications to Orbit Determination

摘要

Several problems in estimation theory with current application interest to orbit determination are treated in the report. Although much of the material covered has general application, the important specific of interplanetary orbit determination is given special emphasis and is used throughout to provide context and to obtain numerical results. Topics covered include: modeling the errors in the navigation measurements, describing the navigation measurements compactly in terms of the unknown parameters, and describing the estimation accuracy in a variety of poorly modeled situations.
