Abstract : This report presents an analysis of the impact errors of a ship- launched ballistic missile produced by an anomalous gravity field. All other error sources are assumed to be absent. The normal earth for which the impact errors would be zero is regarded as spherical and non-rotating. The standard atmosphere is accounted for. Both navigation and in-flight effects are considered, the former under the assumption that the ship remains stationary at the launch point. The treatment is largely deterministic, with elementary statistical concepts being introduced to derive a description of the impact errors applicable to the case of an unknown anomalous field. Some numerical statistical results are presented, in the form of a table for a particular trajectory and as graphs for trajectories having various ranges and times of flight. Possible extensions of the analysis are discussed.
