Optical Telescope Network for LEO Object Detection

The patent replaces radar systems (electromagnetic radiation-based) with optical telescopes (light-based) for LEO object detection. This substitution maintains detection capability while eliminating the high power consumption, magnetic losses, and maintenance costs associated with radar systems, achieving comparable performance at lower operational costs.

The patent divides the LEO monitoring task into multiple distributed optical telescopes positioned at different geographic locations. Each telescope covers a specific orbital inclination range, and the network collectively provides global coverage. This segmentation allows cost-effective monitoring by assigning specialized telescopes to specific orbital zones rather than requiring one comprehensive high-cost system.

The patent implements dynamic exposure time adjustment based on object orbital characteristics. For LEO objects with high apparent motion, the system uses short exposure times (milliseconds to seconds) to prevent trailing and maintain detection accuracy. For GEO/MEO objects with slower motion, longer integration times are employed to maximize sensitivity. This dynamic adaptation resolves the contradiction between sensitivity and tracking speed.

The patent employs frequent, periodic observations of LEO objects using short exposure times. Rather than single long exposures, the system captures multiple rapid successive images, allowing detection of rapidly moving objects while building up signal through repeated measurements. This periodic sampling approach maintains both sensitivity and accurate speed measurement capability.

The patent segments the LEO monitoring function across multiple distributed optical telescopes, each optimized for specific orbital inclination ranges. This geographic and functional segmentation ensures complete coverage of all possible LEO trajectories while maintaining relatively simple individual telescope designs. The network architecture provides redundancy and frequent revisit capability that a single system cannot achieve.

The patent creates a multi-functional network where each optical telescope can observe multiple orbital inclinations and object types (debris, operational satellites, meteorites). The distributed network collectively provides universal coverage of the entire LEO environment, with each node contributing to the overall comprehensive monitoring capability through coordinated observations.

The patent replaces radar systems with optical telescopes, eliminating the need for high-power electrical equipment that is sensitive to temperature and humidity. Optical systems have no magnetic losses, lower power requirements, and greater environmental tolerance, allowing deployment in more favorable locations while maintaining detection capability.

The patent positions optical telescopes at specific latitudes optimized for observing particular orbital inclination ranges (e.g., high-latitude telescopes for polar orbits, equatorial telescopes for equatorial orbits). This local optimization allows each telescope to operate in environmentally favorable conditions while collectively providing global LEO coverage, avoiding the need to place all systems in harsh equatorial zones.
