peedand power. Today, however, computers are vastly more powerful and allow for a greater fidelity with regards togravitational and force models. Additionally, a more comprehensive analysis of the levels of noise and their relation to the performance of theARS would be beneficial. Including more noise values in the neighborhood of the critical points would resolve theperformance boimdaries of the ARS. 10 Appendix Note: The levels of noise on the plots are listed as integers, usually from 1 to 20 or so. The type of noise islisted at the top of the plots, Range, Angle, Range and Angle, or Standard Noise, use this to determinewhich entry on the Noise table the plot is using. For example, a plot of RMS versus Range and Anglenoise for a Lunar orbit with a critical point at Noise Level 18 will be referring to Noise Level 18RA.

This, combined with the increasingRMS, decreases the confidence in the solution and thus marks the limit of the ARS capability.
