Artificial Satellite Identification Using Physical Measurements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication security methods for artificial satellites are inadequate in the face of advanced quantum computing threats, particularly in wireless and free space networks, where physical security is challenging to enforce.
Innovation Solution
Implementing a system that identifies satellites based on physical characteristics such as orbital wobble, reflectivity, and internal measurements, comparing these to known values to generate a certainty score, and adjusting communication security measures accordingly.

Engineering Contradiction Analysis
1Reliability
If traditional encryption methods are used for satellite communication, then communication can be established, but security is inadequate against quantum computing threats
Solution Approach 1:
The patent replaces traditional cryptographic security mechanisms with physical measurement-based identification. Instead of relying on mathematical encryption that may be broken by quantum computers, the system uses physical characteristics (orbital parameters, reflectivity, timing) to identify and verify satellites, substituting a mechanical/physical verification system for a computational security system.
Solution Approach 2:
The patent changes the security verification parameters from cryptographic keys to physical measurement parameters such as orbital position, orbital velocity, reflectivity characteristics, and timing measurements. These physical parameters are inherently difficult to replicate and provide a new basis for secure communication verification that is resistant to quantum computing threats.
2Reliability
If physical measurements are taken to identify satellites, then security is improved, but measurement precision requirements increase
Solution Approach 1:
The patent segments the satellite identification process into multiple independent measurement components: orbital position measurement, orbital velocity measurement, reflectivity measurement, and timing measurement. By dividing the identification into separate measurable parameters, the system can accumulate evidence across multiple dimensions rather than relying on a single high-precision measurement, making the overall identification more robust.
Solution Approach 2:
The patent introduces timing measurements and orbital parameter calculations as intermediary verification steps. These intermediaries translate direct physical measurements into comparable identification data, allowing the system to verify satellite identity through multiple indirect measurement pathways rather than requiring direct high-precision measurement of a single critical parameter.

AI summary
System and techniques to distinguish an artificial satellite from another object are described herein. A physical measurement is gathered of a candidate object for a known satellite in an orbit. This physical measurement is compared to a corresponding known value for the known satellite traveling in the orbit. Based on this comparison, a score is created, the score being a representation of certainty as to whether the candidate object is the known satellite. The score is used to modify a planned communication with the known satellite.
