Criteria used in designing estimators that compute state vector of space vehicle from navigational measurements are compared; under assumption of linearity all criteria lead to same estimator (or filter); if all measurement uncertainties have Gaussian distributions, estimate obtained from optimum filter theory is identical with maximum likelihood estimate; proof is presented that Bayes estimator, which is biased in favor of initial conditions, leads to same result that would be obtained from unbiased estimator to which 6 pseudo-measurements, representing initial conditions, have been added.
