Abstract : A mathematical study is presented of differential formulae, which are useful in the mathematical differential correction of an approximate orbit into better agreement with observation, in the physical or thrust differential correction of a non-rendezvous trajectory into one that intercepts its target, in guidance, in error analysis, and in optimization. The discussion is limited to a comparison of astronomical differential correction methods with the adjoint method that has come into space navigation from ballistics. (Author)
