Dynamic Mode S Address Allocation for Drone Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The limited number of Mode S addresses available poses a challenge for the increasing number of drones and other vehicles requiring unique IDs for operation in controlled airspace, as existing methods assign these addresses permanently or do not provide a dynamic solution.
Innovation Solution
A method and system for dynamically allocating Mode S addresses to vehicles for a finite time, allowing deassignment after the vehicle leaves a predetermined region or upon completion of a specific condition, enabling the address to be reassigned to another vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If Mode S addresses are assigned permanently to drones, then each drone has a stable unique ID for identification, but the limited number of Mode S addresses becomes insufficient for the increasing number of drones operating in airspace
Solution Approach 1:
The patent applies dynamic address allocation where Mode S addresses are assigned temporarily to drones for specific flight operations rather than permanently. The system dynamically allocates addresses from a pool when drones enter controlled airspace and reclaims them when drones exit or complete operations, allowing the same address to be reused multiple times across different drones and flights.
2Quantity of substance
If Mode S addresses are allocated dynamically for short durations, then more drones can operate in controlled airspace with sufficient addresses, but the system complexity increases due to tracking and management requirements
Solution Approach 1:
The patent introduces a ground-based address management system that acts as an intermediary between the limited pool of Mode S addresses and the large number of drones. This centralized system tracks address allocation, monitors drone positions, and automatically manages the lifecycle of address assignments, simplifying the complexity by centralizing control rather than distributing it across multiple drones and air traffic control entities.
3Ease of manufacture
If Mode S addresses are assigned based on permanent registration, then address allocation is simple and straightforward, but the system cannot accommodate the rapidly increasing number of drones entering controlled airspace
Solution Approach 1:
The patent makes Mode S addresses universal by decoupling them from permanent drone identification and making them available as a shared pool for multiple drones. The same address can be assigned to different drones for different flight operations, allowing the system to scale to accommodate increasing numbers of drones without requiring proportionally more addresses, thereby improving both scalability and resource utilization.

AI summary
The invention provides a method for dynamic Mode S address allocation for vehicles. The method comprises: providing a database with a plural number of Mode S addresses; assigning one of the Mode S addresses to a vehicle when a condition is fulfilled, wherein the assigned Mode S address is not available for other vehicles after the assignment; and deassigning the Mode S address from the vehicle when said condition is no longer fulfilled, wherein the deassigned Mode S address is available for assignment to another vehicle after the deassignment.
