Experiments with "wide field" for Space Surveillance Systems in Odessa Astronomical observatory (Ukraine). Prodolzhen eksperiment s "shirokim polem" dlya zadach kontrolya kosmicheskogo prostranstva v Odesskoy astronomicheskoy observatorii

In OAO on point Mayaki (40 km for city) is continued observations geostationary (GSS) and low orbital (LEO) satellites with using more inexpensive domestic, "ready to use", wide field optic lens for the reason: To get limited magnitude on high orbital cosmic object (HEO) to 15m in to view telescope 3 -7 degrees for time accumulation 10-15 sec. To value the possibility of the use WFO for monitoring LEO on low orbit by height less than 2 000 km with limited magnitude to 11m on star for 1 sec. accumulations. 90% LEO from 39 objects are surely identified using catalog NORAD. About obtain the results possible to read in article: "About using wide field lens optics for Space Surveillance Systems in Odessa Astronomical observatory" (in Russian).
A review of published literature shows that the short- lived products of radon decay can exist in two states: elementary ions or ’free’ atoms...Precipitation by diffusion and in an electrical field. The present article contains the results of a study of the distribution of charges among the ’free’ products of radon decay under various conditions of their existence .
About using wide lens field optics for observations artificial satellites and space surveillance (O primenenii shirokopol'nykh linzovykh ob"yektivov dlya zadach kontrolya kosmicheskogo prostranstva, on Russian)

On base results of the observations in Odessa astronomical observatory (Ukraine), is shown. The possibility of the using domestic wide field lens optics for monitoring high orbital objects. With wide field lens optics "Tair-19 5003", limited mag = 15m.5 per 10 seconds of the accumulation, average square-error (ASE) of the measurements of the coordinates slowly moving GSS not more than 2 arcsec. About 90% measurements has ASE less 1 arcsec. At surveillance of the area of the equator by width 5° areas 500 square deg. are discovered 46 active GSS, 12 passive GSS and 2 high elliptical orbital satellites (HEO). Is shown perspective possibility of the use WFO for monitoring LEO height before of 2 000 km. 90% of 39 objects LEO fixed in mode "beam-park" in current 1 hour, surely are identified using catalog NORAD.
