Portable ATC System for Drone Collision Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current collision avoidance systems for UAVs and manned air traffic rely heavily on conventional air traffic control or manned pilots, which can lead to increased workload and are inefficient, especially for drones under 10 kg due to limited sensor range and power constraints.
Innovation Solution
A portable air-traffic control system with ground-based hardware, including ADS-B and transponder receivers, pressure sensors, GPS antennas, and magnetometers, provides real-time air traffic information to drones, enabling them to autonomously avoid collisions without additional onboard hardware.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sensors are installed on UAVs to detect air traffic, then collision avoidance capability is improved, but flight autonomy is reduced due to power consumption and weight
Solution Approach 1:
The patent introduces ground-based detection infrastructure (radars, ADS-B receivers) as intermediaries to detect air traffic. Instead of equipping UAVs with heavy sensors, the system uses external detection resources to provide traffic information to the UAV pilot or control system, thereby achieving collision avoidance without burdening the UAV's power and weight constraints
Solution Approach 2:
The patent replaces physical sensors on UAVs with electronic information systems. By using ground-based detection networks and electronic communication to transmit air traffic information to UAV operators, the system achieves the same safety function without the mechanical burden of onboard sensors, thus preserving flight autonomy
2Reliability
If conventional ATC handles UAV traffic information, then collision avoidance is achieved, but workload of ATC and pilots increases
Solution Approach 1:
The patent segments air traffic management into separate channels: ground-based detection systems independently monitor air traffic and provide information directly to UAV operators through dedicated electronic interfaces. This segmentation prevents UAV traffic information from mixing with conventional ATC workflows, thereby avoiding increased workload for traditional ATC and pilot teams while maintaining collision avoidance effectiveness
3Measurement precision
If ADS-B and transponder receivers are installed on ground, then air traffic detection capability is improved, but system complexity increases
Solution Approach 1:
The patent employs multi-functional ground-based receivers that can detect both ADS-B and transponder signals using the same hardware platform. This universal approach allows a single system to handle multiple detection modes, reducing overall system complexity compared to having separate dedicated systems for each detection type while maintaining comprehensive air traffic detection capability
Solution Approach 2:
The patent combines multiple detection functions (ADS-B reception, transponder detection, GPS tracking) into an integrated ground-based system. By merging these functions into a unified platform with centralized processing, the system achieves high measurement precision for air traffic detection while avoiding the complexity of managing multiple independent systems

AI summary
A miniaturized, portable and automatic air-traffic control (ATC) system to determine the position of air vehicles is described. The system is composed by a portable control tower that detects manned air traffic equipped with ADS-B or transponder, and a computer compatible software to display the position of the detected air vehicles. This system is used in conjunction with a drone system, providing to the latter the air-traffic local information. The information given to the drone system allows performing automatic collision avoidance with the air vehicles detected in the flight area of the drone.
