The Estimate of the Small Space Debris Danger for Space Activities and Near-Earth Ecology

Abstract

In contrast to large orbital debris, the impact of small one on space activities and ecology of the Earth and near-Earth space is often underestimated. As shown in this paper, it is unfair. According to the data from different sources, the amount, mass, and dynamics of the small orbital debris population in LEO, its danger to space activity are estimated as well as the consequences of multi-satellite communication space systems deployment being planned now. The latter makes the study of this area particularly relevant. Various aspects of the consequences of technogenic contamination of near-Earth space are considered, as well as the danger of small space debris to space activities and the ecology of the Earth and near-Earth space in comparison to the danger of large debris. The significant lack of complete and reliable information on small space debris due to the shortage of sensors that can observe it is marked.

Comparison of Coordinate Data by Radio-Technical Systems for Sustainable Development of Territories

“…It is known that sustainable development of territories involves limiting the negative impact of economic and other human activities on the environment, as well as ensuring protection and rational use of natural resources in the interests of current and future generations [1]. However, increase in the number of objects [2] caused by human activity in near-Earth airspace (NEAS) requires an increase in the number of various ground-based observation systems [3,4]. At present, the largest contribution to the scope of coordinate data obtained from NEAS falls on radar observation systems (ROS) [5].…”
