Features of Space Debris Survey in LEO Utilizing Optical Sensors

This paper focuses on the features of optical observations of space debris (SD) in Low Earth Orbit (LEO) in a survey mode. These issues for LEO are at present time studied much less comparing to High Earth Orbit (HEO) and, particularly, geostationary orbits.Preferable regions of celestial sphere for LEO SD observation in a survey mode are localized by modeling passes of catalogued SD through the telescope's coverage area and taking into account the conditions of optical visibility. The dependence of these area characteristics on local time, season of observation and latitude of telescope location are studied.The results can represent practical interest for development of the efficient strategies for LEO SD searching, planning the observation campaigns, analysis of the obtained measurement data and validation of the SD models based on the optical observations.
