  In the first paper of this series we examined existing methods of optical
meteor trajectory estimation and developed a novel method which simultaneously
uses both the geometry and the dynamics of meteors to constrain their
trajectories. We also developed a simulator which uses an ablation model to
generate realistic synthetic meteor trajectories which we use to test meteor
trajectory solvers. In this second paper, we perform simulation validation to
estimate radiant and velocity accuracy which may be achieved by various meteor
observation systems as applied to several meteor showers. For low-resolution
all-sky systems, where the meteor deceleration is generally not measurable, the
multi-parameter fit method assuming a constant velocity better reproduces the
radiant and speed of synthetic meteors. For moderate field of view systems, our
novel method performs the best at all convergence angles, while multi-parameter
fit methods generally produce larger speed errors. For high-resolution, narrow
field of view systems, we find our new method of trajectory estimation
reproduces radiant and speed more accurately than all other methods tested. The
ablation properties of meteoroids are commonly found to be the limiting factor
in velocity accuracy. We show that the true radiant dispersion of meteor
showers can be reliably measured with moderate field of view (or more precise)
systems provided appropriate methods of meteor trajectory estimation are
employed. Finally, we compare estimated and real angular radiant uncertainty
and show that for the solvers tested the real radiant error is on average
underestimated by a factor of two.
