UAV Flight Control Using Distance-Based No-Fly Zone Response
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems lack effective methods for controlling unmanned aerial vehicles (UAVs) to respond to flight-restricted regions, such as airports, where UAVs are prohibited from flying, posing safety and regulatory challenges.
Innovation Solution
A method and apparatus that determine the relative location of a UAV to flight-restricted regions by calculating distances and generating flight restriction zones, allowing for appropriate responses such as landing, alerting operators, or altering altitudes, using processors to select and manage flight restriction zones based on boundary data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If flight restriction zones are implemented to prevent UAVs from entering restricted areas, then safety and regulatory compliance are improved, but device complexity and operational constraints increase
Solution Approach 1:
The system pre-defines flight restriction zones with geographic boundaries and stores them in a database before UAV operation. During flight, the UAV simply checks its GPS location against these pre-defined zones rather than performing complex real-time analysis, thereby ensuring safety compliance without adding significant operational complexity
Solution Approach 2:
The system continuously monitors UAV position via GPS and provides real-time feedback when the UAV approaches or enters a flight restriction zone. The flight control system receives this feedback and automatically implements corrective actions (altering course, changing altitude, or landing), creating a closed-loop control system that ensures regulatory compliance while maintaining operational simplicity
2Loss of time
If automated flight response measures are implemented near restricted regions, then response time and safety are improved, but loss of operator control and system complexity increase
Solution Approach 1:
The system implements dynamic, distance-based response measures that adapt automatically based on the UAV's proximity to flight restriction zones. When the UAV is far from restricted areas, the system provides warnings and allows operator control. As the UAV approaches, the system progressively restricts control and eventually implements automated corrective actions, creating a dynamic balance between operator control and automated safety responses
Solution Approach 2:
The flight control system acts as an intermediary between the operator and the UAV when approaching flight restriction zones. Rather than directly controlling the UAV or immediately restricting operator input, the flight control system processes distance calculations and provides graduated responses (warnings, suggestions, then mandatory corrections), serving as a mediating layer that preserves operator involvement while ensuring safety compliance

AI summary
Systems, methods, and devices are provided for providing flight response to flight-restricted regions. The location of an unmanned aerial vehicle (UAV) may be compared with a location of a flight-restricted region. If needed a flight-response measure may be taken by the UAV to prevent the UAV from flying in a no-fly zone. Different flight-response measures may be taken based on the distance between the UAV and the flight-restricted region and the rules of a jurisdiction within which the UAV falls.
