Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ground-based sensors are unable to effectively track and characterize small, lethal non-trackable space debris due to their high angular velocity and limited detection capabilities, posing a significant risk to space missions.
Innovation Solution
A network of satellites equipped with plasma perturbation tips and Langmuir probe arrays that propagate and receive solitary plasma waves to detect and track debris by measuring phase shifts and amplitude changes in these waves, allowing for precise detection and characterization of debris without collision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If ground-based sensors are used to detect debris, then detection capability for large objects is improved, but detection capability for small debris deteriorates due to high angular velocity and limited field of view
Solution Approach 1:
The patent transitions from ground-based detection to space-based detection, moving the sensor platform from Earth's surface to orbit. This dimensional change allows the sensors to detect small debris across all altitudes without being constrained by Earth's curvature and atmospheric interference, enabling detection of objects with high angular velocity that ground-based sensors cannot track.
2Quantity of substance
If ground-based sensors operate in staring mode to count objects, then object counting is possible, but tracking capability deteriorates due to small field of view and high angular velocity requirements
Solution Approach 1:
The space-based sensor system employs dynamic tracking capabilities that can follow high-angular-velocity objects. Unlike ground-based staring sensors, the space-based platform can actively track and characterize small debris trajectories in real-time, providing precise measurement of object positions and velocities without being limited by a fixed field of view.
3Measurement precision
If indirect space-based techniques are used to detect plasma waves, then debris detection is possible, but detection range is limited to 1 km to 50 km based on debris particle size
Solution Approach 1:
The patent uses plasma waves as an intermediary medium to detect small debris. By propagating plasma waves through the detection area and analyzing interactions with debris-generated plasma waves, the system extends detection range beyond the limitations of direct optical or radar methods, enabling detection of sub-centimeter objects at distances greater than 50 km.
4Length of stationary object
If space-based plasma wave detection is implemented, then detection range for small debris is improved, but system complexity increases due to plasma perturbation tips and Langmuir probe arrays
Solution Approach 1:
The plasma perturbation tips on the transmitting satellite self-generate plasma waves by interacting with the ionospheric plasma environment. The Langmuir probe arrays on the receiving satellite automatically detect plasma wave characteristics without requiring complex external calibration systems. The system utilizes the natural plasma environment as both the transmission medium and the detection target, reducing the need for additional complex subsystems.
