The formulas used in a computer program to fit earth satellite orbits to data are documented. The areas covered are 1 iterative method of determining maximum likelihood parameter estimates 2 units are coordinate systems 3 motion of the earth about its center of mass 4 equations for earth satellite motion and partial derivatives of this motion with respect to parameters 5 theoretical values and partial derivatives of theoretical values of ground based radar or radio transponder, look angles, long baseline interferometer and satellite based radar, look angles observables and 6 numerical techniques such as numerical integration, polynomial interpolation and matrix inversion. Observations of the sun, moon, planets and stars are also discussed.
