Recent advances with space navigation technologies developed by NASA in space-based atomic clocks and pulsar X-ray combined past successes autonomous using optical imaging, brings to the forefront need compare optical, radiometric, pulsar-based measurements a common set of assumptions techniques. This review article examines these data types two different ways. First, simplified deep orbit determination problem is posed that captures key features dynamics geometry, then each type characterized for its ability solve orbit. The are compared contrasted semi-analytical approach geometric dilution precision results provide useful parametric insights into strengths type. In second part paper, high-fidelity, Monte Carlo simulation Mars cruise, approach, entry studied. found complement semi-analytic first part, illustrate specific issues such as type's quantitative impact on solution accuracy their support delivery planet.
