Abstract: On the basis of our observation results, it is shown that wide-field lens optics can be used for the monitoring of high-orbital artificial Earth’s satellite objects with the aim of their orbital determination. With the wide-field lens optics «Tair-19 500/3», at a limited magnitude of 15.5m in an accumulation time of per 10 sec, the rms error for the coordinate measurements in the case of geostationary satellites moving slowly does not exceed 2 arcsec. For about 90 % measurements, the rms error is less than 1 arcsec. All of active 46 catalogued geostationary satellites with declinations less than 2.5° were detected during the survey of the geostationary zone from 10° E to 37° W (the zone width was 5° and zone area was 500 deg2). The possibility to use wide-field optics for the monitoring of LEOs with altitudes up to 2000 km is shown. Among the 39 objects observed during 1 hour in the «beam-park» mode with a field of view of 30°×30° 35 objects were identified in the NORAD catalogue.
