UAV Transponder Disablement via Airspace Interrogation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Unmanned aerial vehicles (UAVs) pose safety and privacy concerns when operated inappropriately, particularly near sensitive areas like airports or government facilities, as existing systems lack effective methods to manage and disable UAVs within restricted airspace.
Innovation Solution
An airspace management system that transmits identifier requests to UAVs, determines their location, and accesses databases to assess permissions, sending disablement instructions if the UAV is in restricted airspace, using encryption keys to authenticate and execute disablement procedures such as forced landing or flight path reversal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If an airspace management system transmits disablement instructions to UAVs in restricted airspace, then public safety and privacy are improved, but the complexity of the system increases due to integrated transponder and disablement functionality
Solution Approach 1:
The patent combines the transponder system and disablement system into a single integrated UAV system. The transponder component handles identification and communication with ground stations, while the disablement component executes safety protocols when restricted airspace is detected. This merging reduces the number of separate systems needed and streamlines the overall architecture.
Solution Approach 2:
The ground-based airspace management system acts as an intermediary between UAVs and the disablement mechanism. It receives transponder signals, determines airspace violations, and transmits authenticated disablement instructions only when necessary. This intermediary approach enables centralized control while maintaining system modularity.
2Reliability
If encryption keys are used to authenticate disablement instructions, then system security is improved, but the complexity of authentication and communication protocols increases
Solution Approach 1:
The system uses encryption keys as a parameter change to secure communication. Each UAV is assigned a unique encryption key that transforms the authentication process from simple signal recognition to cryptographic verification. This parameter change (adding encryption) significantly enhances security while the key management system handles the complexity.
Solution Approach 2:
Encryption keys are pre-loaded into UAVs during manufacturing or registration before deployment. This preliminary action ensures that authentication capability is already present in the UAV, eliminating the need for complex real-time key exchange protocols during operational disablement scenarios.
3Loss of time
If the UAV transponder system includes integrated disablement capability, then response time to unauthorized flights is improved, but the device complexity increases
Solution Approach 1:
The disablement functionality is pre-configured within the transponder system, with all necessary protocols and authentication mechanisms already in place. When a violation occurs, the system can immediately execute disablement without requiring external configuration or complex real-time decision algorithms, reducing response time.
Solution Approach 2:
The UAV's transponder system autonomously monitors its own operational status and can self-disable when receiving authenticated disablement instructions. This self-service capability eliminates the need for external physical intervention or complex multi-system coordination, enabling rapid response to airspace violations.

AI summary
Various systems and methods for disabling UAVs are presented. An interrogation system may transmit an identifier request message to a UAV. The interrogation system may receive, in response to the identifier request message, a response message that indicates a UAV identifier. The interrogation system may access one or more UAV identifier databases that relate UAV identifiers with airspace definitions. The interrogation system may retrieve from the one or more UAV identifier database systems an airspace definition corresponding to the UAV identifier. The interrogation system may determine that the UAV is to be disabled based on: a location of the UAV, a restricted airspace definition, and the airspace definition corresponding to the UAV identifier. The interrogation system may then transmit a disablement instruction message to the UAV based on the location of the UAV and the airspace definition corresponding to the UAV identifier.
