A general simulation program for state estimation of a nonlinear space vehicle flight navigation system is developed and used as a basis for evaluating the performance of a Space Tug navigation system. An explanation of the iterative guidance mode guidance law, derivation of the dynamics, coordinate frames and state estimation routines are given in order to clarify the assumptions and approximations made. Included in the simulation studies are (1) initial offset vector parameter study; (2) propagation time vs. accuracy; (3) measurement noise parametric study and (4) reduction in computational burden of an on-board implementable scheme. Conclusions and recommendations concerning future areas of practical and theoretical work are presented.
