An embedded function tool for modeling and simulating estimation problems in aerospace engineering
Additional Document Info
An automatic differentiation-based embedded function tool, OCEA (Object Oriented Coordinate Embedding Method), is presented for solving common estimation problems in Aerospace Engineering. The orbit determination and ballistic projectile parameter estimation problems have been chosen as examples. OCEA is extremely useful for computing n order partial derivatives of scalar, vector, matrix, and higher dimension tensor functions for these applications. Both applications consider algorithm performance and robustness issues associated with applying high order generalizations of the classical first-order optimization and estimation algorithms. OCEA -based tools are expected to have broad applicability for Aerospace problems in particular and engineering problems in general.
