“…As was shown previously (Gorbanev et al, 2006), the frame change accuracy of the patrol TV system is at least 0.1 ms and the timing accuracy deteriorates only due to the existence of tails in meteors. The focal length of our telescope is 534 mm and the accuracy of determining the beginning and end of the meteor streak is ~2′′.…”

“…THE METEOR DATABASE After a night of meteor patrolling, whose technique was described previously (Gorbanev et al, 2006), movies consisting of 50 frames before and after the meteor event and frames with meteor trails are entered into the database. This procedure is performed using our AVICutter 1.02 software, which directly cuts out frames with meteor trails from the movie and produces images for even and odd frame lines.…”

“…The meteor patrol at the Kryzhanovka observing station of the Odessa Astronomical Observatory was described previously (Gorbanev et al, 2006). The patrol was installed on the APSh-4 equatorial mounting and equipped with a Schmidt telescope (the correction plate diameter is 170 mm and the mirror diameter is 300 mm).…”

We present the results of our positional reduction of the observational material obtained using a meteor patrol based on a Schmidt telescope and a TV CCD detector. More that 1000 telescopic meteors were recorded in three years of meteor patrolling. Techniques for the cataloging and positional reduction of 3050 TV images with meteor trails are described. We have developed a technique for measuring the images of reference stars to determine the rectangular coordinates in the image frame. We discuss the achieved accuracy of determining the equatorial coordinates of reference and check stars by Turner's method (of the order of a few arcseconds). We have developed software that allows the rectangular coordinates of meteor trajectory points to be determined after the meteor image reduction. These coordinates are used to determine the equatorial coordinates of the poles of the great circles of meteor trajectories (the angular length is not less than 15 ′ with an accuracy of at least 4 ′ . We consider the possibility of using Stanyukovich's method to determine the equatorial coordinates of radiants for non-basis meteor observations. The accuracy of determining the radiant coordinates has been estimated to be 4 ′ -5 ′ . Prospects for obtaining the kinematic characteristics of meteor particles are discussed.

“…Meteor observation using video techniques was started at Research Institute «Mykolaiv astronomical observatory» (RI MAO) in 2011. This is the third big meteor research campaign in Ukraine after Odessa (Gorbanev, et al, 2006;Gorbanev, 2009) and Kiev (Hajdukova, et al, 1995;Kozak, 2001). The research is based on a system of fixed telescopes equipped with TV CCD cameras for both single and double station observation.…”

Regular meteor observation using TV CCD unintensified techniques was started in 2011 in RI «Mykolaiv astronomical observatory» (RI MAO). The method of meteor registration is based on using "trackand-stack" technique for obtaining frames with reference stars and online meteor detection software developed at RI NAO. The main accent of the research is made on precise astrometry and meteoroid orbits calculation. New observational campaign with baselines 11.7 and 100 km was started in 2017-2018 in collaboration with Astronomical Observatory of the I.I. Mechnikov Odessa National University. Eight telescopes with narrow field lens (f=50 mm, f/1.2) were installed in Mykolaiv and Odessa. More than 3000 single station meteors and 221 double station meteors were detected during 2017-2018. Uncertainties of meteor trajectory and orbital parameters are calculated using Monte Carlo method. Catalog of meteor trajectory positions and photometric parameters has created. Standard deviation of approximation of a meteoric trajectory in a large circle is (15-20)". Kinematic parameters of atmospheric meteoric trajectories and elements of heliocentric orbits for 3 meteors were calculated based on the results of television observations with cameras with a field of view <10° at a baseline distance 100 km. The average uncertainty of visible radiant estimation is in (0.3-0.7)º with baseline 100 km. The geocentric velocity estimation uncertainty is 0.5 km/s, elevation uncertainty is 50-150 m.
