Drone Airspace Layering for Collision-Free Sector Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Managing the airspace of large groups of drones effectively to prevent collisions and ensure efficient data collection over large geographic areas, particularly in disaster scenarios, is challenging due to the complexity of coordinating their flight paths and sensor data integration.
Innovation Solution
A layer approach is implemented, dividing airspace into vertical layers and horizontal sectors, with drones assigned to specific sectors and programmed flight paths, using different types of drones and sensors based on altitude and characteristics, and employing transition spaces to avoid collisions and optimize data collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If airspace is divided into layers and sectors with multiple drones assigned, then data collection coverage and efficiency are improved, but collision risk and coordination complexity increase
Solution Approach 1:
The airspace is divided into multiple vertical layers and horizontal sectors, creating a grid structure that organizes drone operations. Each sector can independently manage drones, reducing overall coordination complexity while maintaining high data collection efficiency through parallel operations across multiple sectors
Solution Approach 2:
A central management system acts as an intermediary that assigns drones to specific sectors and layers, coordinates transitions between sectors, and manages collision avoidance. This mediator handles the coordination complexity centrally, allowing individual sectors to operate independently for efficient data collection
2Quantity of substance
If more drones are deployed to cover large areas, then data collection comprehensiveness is improved, but collision risk and airspace management difficulty increase
Solution Approach 1:
By segmenting the airspace into layers and sectors, the system can deploy numerous drones across different spatial zones simultaneously. Each sector manages its own drones independently, preventing collisions through spatial separation while enabling comprehensive area coverage through the combined effort of many drones
Solution Approach 2:
The system adds vertical dimension by dividing airspace into multiple layers at different altitudes. This allows drones to operate in three-dimensional space rather than just horizontal planes, increasing capacity for drone deployment while maintaining safe separation distances and reducing collision risk through vertical stratification
3Area of stationary object
If drones operate at higher altitudes for broader coverage, then area coverage is improved, but sensor resolution and data quality may deteriorate
Solution Approach 1:
The vertical segmentation into multiple layers allows different types of data collection operations at different altitudes. Higher layers provide broad area coverage for macro-level assessment, while lower layers enable detailed sensor measurements for micro-level analysis, and the system integrates data from both levels
Solution Approach 2:
Different layers are assigned different operational characteristics appropriate to their altitude. Lower layers near the ground provide high-resolution detailed data for specific locations, while higher layers provide lower-resolution broad coverage data, with each layer optimized for its specific function rather than attempting uniform performance across all altitudes

AI summary
A method for coordinating drones flying in a divided airspace that includes sending patrol instructions to each drone of a set of airborne drones in a divided airspace, where the divided airspace includes mutually exclusive horizontal layers having a ceiling altitude and a floor altitude and at least one transition space layer, where the layers comprise sectors, where the patrol instructions direct the drone into a flight path in a sector, sending first transition instructions to a first drone, where the transition instructions direct the first drone to move from its sector to a transition space layer and from the transition space layer to exit the divided airspace, sending second transition instructions to a second drone, where the second transition instructions direct the second drone to move from outside the divided airspace to a transition space layer and from the transition space layer to the sector of the first drone.
