Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current air traffic control systems are inadequate for managing the large number of drones, as they are not scalable to handle the sheer quantity of unmanned aerial vehicles (UAVs) and do not effectively integrate communication for autonomous flight control, especially with dynamic and static obstructions.
Innovation Solution

1Quantity of substance
If existing air traffic control network is used for drones, then communication infrastructure is available, but the system cannot handle the sheer quantity of drones and is not scalable
Solution Approach 1:
The air traffic control system is segmented into multiple Unmanned Aircraft Service Stations (UASS) that each manage specific geographic regions or groups of drones. This segmentation allows the system to scale by adding more UASS units rather than overloading a single centralized control system, directly addressing the capability to handle large quantities of drones while maintaining manageable system complexity.
Solution Approach 2:
The patent introduces a hierarchical dimension to the air traffic control architecture, with multiple levels of control (individual UASS units, regional coordination, and national oversight). This dimensional expansion allows the system to manage vast numbers of drones by distributing control across multiple layers, transforming the scalability challenge from a horizontal bottleneck into a vertically structured solution.
2Extent of automation
If autonomous flight control communication is integrated, then drone operation autonomy is improved, but system complexity and communication requirements increase
Solution Approach 1:
The wireless communication system is designed to perform multiple functions simultaneously: it provides autonomous flight control commands, transmits weather information, communicates obstruction data, and manages drone identification and tracking. This multi-functionality reduces the need for separate dedicated communication channels for each function, thereby managing system complexity while supporting comprehensive autonomous operation.
Solution Approach 2:
The UASS acts as an intermediary between the drones and the broader air traffic control infrastructure, processing and relaying information between autonomous drones and ground control systems. This intermediary layer simplifies communication by handling data aggregation, filtering, and routing, thereby reducing the direct communication burden between individual drones and the complex national air traffic control network.
3Reliability
If real-time obstruction detection and management is implemented, then flight safety is improved, but system complexity and data processing requirements increase
Solution Approach 1:
The system performs preliminary obstruction detection and route planning before drone flights commence. By identifying potential obstructions and calculating safe flight paths in advance, the system reduces the complexity of real-time decision-making during flight while maintaining high safety standards. This proactive approach allows autonomous drones to operate with pre-approved routes that account for known obstructions.
Solution Approach 2:
The obstruction management system implements continuous feedback loops where drones report detected obstructions back to the UASS, which then updates flight paths and communicates corrections to affected drones. This feedback mechanism distributes the data processing burden across the network rather than requiring a single centralized system to analyze all obstruction data, thereby improving safety while managing system complexity through distributed intelligence.

AI summary
A passenger drone includes a processing device communicatively coupled to the flight components, cameras, radar, and wireless interfaces; and memory storing instructions that, when executed, cause the processing device to receive notifications from an air traffic control system via the one or more wireless interfaces, the notifications related to previously detected obstructions in a flight path associated with a flight plan of the passenger drone, wherein the previously detected obstructions include objects at or near ground level; monitor proximate airspace with at least one of the one or more cameras and radar; detect an obstruction based on monitoring the proximate airspace, wherein the detected obstruction includes one or more objects at or near ground level in the flight path; alter the flight plan, to be carried out by the flight components, if required, based on the detected obstruction.
