UAV Landing Guidance Using Airdrome Position Detectors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing unmanned aerial vehicle (UAV) landing systems face challenges due to GPS data drift, leading to inaccurate landings and increased operational costs, as manual updates are labor-intensive and prone to errors.
Innovation Solution
An airdrome auxiliary positioning system that uses multiple position detectors to determine the UAV's location over a target airdrome, generates correction guidance information based on the offset vector between the actual and target locations, and sends this information to the UAV to guide it into the signal coverage of a guidance beacon for precise landing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual updates are used to correct GPS data drift, then positioning accuracy can be improved, but labor intensity and operational costs increase
Solution Approach 1:
The system uses the UAV's own transmitted signal as the measurement target for position detectors, enabling automatic positioning correction without manual intervention. The UAV serves itself as both the signal source and the measurement object, eliminating the need for manual GPS updates.
Solution Approach 2:
The patent replaces manual mechanical operations with an automated electronic system. Position detectors automatically measure the UAV's position by analyzing its transmitted signal, and the system automatically generates correction guidance information, substituting manual labor with automated detection and processing.
2Manufacturing precision
If extensive manual updates are performed to maintain positioning accuracy, then landing precision improves, but time consumption and operational complexity increase
Solution Approach 1:
The system continuously tracks the UAV's position by constantly measuring its transmitted signal during flight. This continuous automatic measurement and correction process maintains landing precision throughout the entire flight without requiring intermittent manual updates, saving time and reducing operational complexity.
Solution Approach 2:
The patent introduces position detectors as an intermediary between the UAV and the control system. These detectors automatically measure the UAV's position by receiving its signal and generate correction guidance information, eliminating the need for manual measurement and update operations.
3Device complexity
If GPS data is used without correction, then system simplicity is maintained, but positioning accuracy and landing reliability deteriorate
Solution Approach 1:
The patent introduces position detectors as an intermediary component that automatically measures the UAV's position and generates correction guidance information. This intermediary system bridges the gap between the simple GPS and the control system, improving reliability without requiring complex manual intervention procedures.
