“…Another automated system to observe video meteors is the Canadian Automated Meteor Observatory (CAMO). Their wide-field camera system, appropriate for measurements of meteoroid fluxes, has average radiant errors of 0.3 deg and speed uncertainties of 3 % (Weryk et al, 2013;Musci et al, 2012). (Trigo-Rodriguez et al, 2007, 2008Madiedo et al, 2008), which uses high-sensitivity CCD video devices and CCD all-sky cameras, provides high accuracy orbits of meteors, especially fireballs.…”

We use the Slovak and Czech video meteor observations, as well as video meteoroid orbits collected in the CAMS, SonotaCo, EDMOND and DMS catalogues, for an analysis of the distribution of meteoroid orbits within the stream of the Geminids and of the dispersion of their radiants. We concentrate on the influence of the measurement errors on the precision of the orbits obtained from the video networks that are based on various meteordetection software packages and various meteor orbital element softwares.The Geminids radiant dispersion obtained from the large video catalogues reaches the dispersion of the radio observed Geminids, wherby the diffused marginal regions are affected mostly by meteoroids with extreme values (small or large) of the semi-major axes. Meteoroids of shorter semimajor axes concentrate at the eastern side of the radiant area and those of longer semi-major axes at the western part.The observed orbital dispersions in the Geminid stream described by the median absolute deviation range from 0.029 to 0.042 AU −1 for the video catalogues. The distribution of the semi-major axes of video meteors in all the databases, except for the Ondřejov (Czech) data, seem to be systematically biased in comparison with the photographic and radio meteors. The determined velocities of the video data are underestimated, probably as a consequence of the methods used for the positional and velocity measurements. The largest shift is observed in the EDMOND and SonotaCo catalogues.Except for the measurement errors which influence the analyses and their interpretations, we also point out the problem of the uncertainties of the numerical integration procedures that influence the simulations' results. Several experimental integrations of the Geminids parent asteroid, which we performed from the present to the past and then back to the year 2015, showed that a complete reproduction, including also the mean anomaly, is only possible for a time span of about 2700 years.

Context. The structure and composition of meteoroids is of great interest because of the insight it provides into their parent asteroids and comets. Aims. Recently acquired, high-resolution video measurements of meteors will be used to evaluate two models of meteoroid ablation. Methods. Ten meteors were observed with the Canadian Automated Meteor Observatory (CAMO), which uses pairs of mirrors to track meteors telescopically in the sky with a resolution of up to 3 meters per pixel. Two meteoroid ablation models were used to fit the wide-field light curves and deceleration measurements of the meteors, and the wakes predicted by each model were compared to the wakes measured in the telescopic system. Results. Both models produced satisfactory fits to the wide field measurements, but both were very poor at predicting the narrow field brightness profiles of the meteors. Conclusions. Models of meteoroid fragmentation in the atmosphere need significant improvement to match observations. Data from the CAMO observatory mirror systems provide significant constraints and can be used in the development of a new model of meteoroid ablation.
