Autonomous Aerial Vehicle Data Link Loss Response
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current unmanned aerial systems lack the ability to autonomously respond to critical situations such as communication link loss, relying solely on automated processes without human intervention, which can lead to unpredictable behavior in emergency conditions.
Innovation Solution
A method and system for autonomous controlling of remote-controlled aerial vehicles that initializes a data link with a ground segment, determines operation conditions, and issues autonomous controlling commands in case of data link loss, ensuring predictable behavior and safety through a communication unit, evaluation unit, and command unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If autonomous controlling commands are issued upon data link loss, then safety and predictable behavior are improved, but system complexity increases
Solution Approach 1:
The system pre-defines autonomous controlling commands and evaluation criteria before data link loss occurs. The flight control system is pre-configured with specific actions to take (e.g., return-to-launch, land, maintain position) and the criteria for evaluating data link operation conditions, enabling immediate autonomous response without complex real-time decision-making algorithms.
Solution Approach 2:
The aerial vehicle autonomously evaluates its own data link operation conditions and executes predetermined controlling commands without external intervention. The flight control system continuously monitors data link status and automatically triggers appropriate safety protocols when degradation is detected, making the system self-regulating and reducing overall complexity.
2Reliability
If autonomous controlling commands are issued upon data link loss, then reliability is improved, but ease of operation deteriorates
Solution Approach 1:
The system continuously monitors data link operation conditions and provides feedback to the flight control system. When the evaluation unit detects that data link conditions have degraded below predetermined thresholds, it automatically triggers the appropriate autonomous controlling command, creating a closed-loop feedback system that enhances safety without requiring operator intervention.
Solution Approach 2:
All possible data link failure scenarios and corresponding autonomous responses are pre-configured before flight operations begin. The system has predetermined evaluation criteria and ready-to-execute commands for various data link loss conditions, eliminating the need for complex real-time operator decisions and simplifying operation while maintaining high reliability.

AI summary
A method for autonomous controlling of a remote controlled aerial vehicle, wherein a flight operator commands the aerial vehicle, comprising the steps of: initializing a data link between the aerial vehicle and a ground segment; determining an operation condition of the data link during use of the data link; and issuing at least one autonomous controlling command, if, as a result of the determining, a loss of the data link is determined.
