Abstract

The problem of surveillance of the current state of the multitude of orbiting objects has two components. The first is detection and registering of new orbital objects, the second, updating the current information about the orbits of already registered objects. The second problem is solved by periodical adjustment of their parameters during the sessions of observation. The number of orbital objects, whose parameters are to be periodically corrected, is large; resources of the surface observation centers are insufficient for surveillance of all orbital objects on intervals of their visibility from the centers. Therefore, planning of surveillance is essential.

A way to efficient monitoring of the state of the system of orbiting objects is the world-wide cooperation in centralized collection, storage and practical use of the information about the objects on the near-Earth orbits. Currently, the implementation of joining of activities in this area is beginning; a considerable part of regularly renewed information from the centers of surveillance of the near-Earth space is widely available for use. Tendencies to joining information systems collecting data on the near-Earth space begin to appear. However, currently, these are limited to combining uncoordinated observation data for their joined processing and storage.

A substantial increase of the efficiency of the monitoring could be achieved through centralized planning of surveillance. Centrally coordinated surveillance of the near-Earth space will allow one to substantially increase the volume and reliability of data on the orbiting objects. First, such planning will make it possible to globalize the strategy and coordination of collecting and processing space monitoring data from different facilities. Second, the centralized planning of the surveillance by territorially spaced surface observation stations gives a possibility of a global optimization of surveillance. Thus, by territorially distributed observation resources it is possible: to increase the number of objects under surveillance at a given time interval, to provide more frequenter observation of each orbital object (to increase the number of observations of an object in the intervals of its visibility from the surface stations), to provide observations during those intervals of visibility, in which the quality of obtained data will be sufficiently high.

In this work we represent the outcomes of the analysis of efficiency of the centralized planning of orbital objects observations from territorially distributed surface centers. Methods of working out quasi-optimized plans of observations for a given number of orbital objects and a network of territorially distributed surface stations are proposed.
