Satellite Sky Imaging for Space Debris Characterization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for characterizing the space environment around Earth are inadequate for detecting smaller debris objects due to limitations in detection capabilities, particularly in identifying and quantifying space debris in high-density areas.
Innovation Solution
The use of a satellite equipped with space optics to capture images of the sky around Earth, allowing for the identification and characterization of uncharacterized objects within the image, including smaller debris objects, by employing image processing techniques and databases for known astronomical objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional detection methods are used, then detection capabilities are limited, but smaller debris objects cannot be detected
Solution Approach 1:
The patent segments the sky area into multiple regions of interest and processes images through multiple passes, allowing systematic detection of small debris objects across large areas while maintaining detection precision
Solution Approach 2:
The patent transitions from ground-based detection to space-based detection, changing the observation dimension to achieve superior resolution and detect smaller debris objects that are undetectable from Earth's surface
2Quantity of substance
If conventional methods are used, then detection capabilities are sufficient for large objects, but identification and quantification in high-density areas is inadequate
Solution Approach 1:
The patent implements feedback loops where detection results from one pass inform subsequent processing passes, allowing iterative refinement of debris identification and quantification in high-density areas
Solution Approach 2:
The patent performs preliminary identification of known astronomical objects and removes them from consideration before detecting space debris, streamlining the identification process and improving quantification accuracy in crowded fields
