Ground-Based UAV Detection Using Remote ID for Local Airspace Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Unmanned aerial system traffic management (UTM) systems struggle to provide precise instructions to unmanned aerial vehicles (UAVs) in small, specific areas, such as arenas or stadiums, due to limitations in detecting and avoiding obstacles and maintaining safe flight paths.
Innovation Solution
A ground-based system, referred to as an Area Airspace Manager (AAM), establishes direct communication with UAVs using Remote IDs and PC5 interfaces to provide local detect-and-avoid policies, enabling real-time steering and control to prevent collisions and ensure safe operation within specific areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a ground-based system uses traditional UTM methods to manage UAVs, then UAV traffic can be managed in general areas, but precise local policies cannot be provided in small specific areas like arenas or stadiums
Solution Approach 1:
The system segments the management area into general UTM coverage zones and specific local zones (arenas, stadiums) with dedicated ground-based detection and communication devices. This segmentation allows different management approaches: general UTM for broad areas and precise local detection for small specific areas, resolving the contradiction between detection precision and coverage area.
Solution Approach 2:
The patent implements local quality by deploying ground-based detection and communication devices specifically in areas requiring precise local policies (arenas, stadiums). These localized devices provide enhanced detection precision and targeted communication exactly where needed, while other areas continue to use standard UTM methods, thus achieving high precision in specific locations without sacrificing overall coverage.
2Productivity
If direct communication with UAVs is established using Remote IDs and PC5 interfaces, then real-time steering and control can be provided, but system complexity increases
Solution Approach 1:
The ground-based detection and communication devices serve as intermediaries between UAVs and the UTM system. These intermediaries establish direct communication with UAVs using Remote IDs and PC5 interfaces, enabling real-time steering and control for improved operational efficiency. The intermediary layer manages the complexity by handling direct communications locally, reducing the burden on the central UTM system while maintaining overall system coordination.
3Reliability
If ground-based detection devices are deployed in specific areas, then precise local policies can be provided, but the system becomes more complex and costly
Solution Approach 1:
The system performs preliminary action by pre-configuring ground-based detection and communication devices in specific areas before UAV operations begin. This advance deployment ensures that precise local policies and detection capabilities are already in place, enhancing safety from the outset. The preliminary setup allows the system to handle complex detection and communication functions in advance, reducing operational complexity during actual UAV missions.
