Aircraft Localization Cross-Checking for Automated Terminal Operations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aircraft navigation systems lack the precision and reliability required for automated flight operations, particularly during critical phases like takeoffs and landings, due to interference and maintenance costs of existing apparatus.
Innovation Solution
A system that processes sensor-derived data to dynamically generate updated analyses of an aircraft's position and orientation, cross-checking localization information between aircraft and remote components, and adjusts flight control instructions in real-time to reduce 'worst-case' bounds and improve accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If current navigation systems are used, then aircraft can perform basic navigation, but localization precision is insufficient for automated flight operations
Solution Approach 1:
The patent combines multiple independent localization systems (GPS, inertial navigation, ground-based navigation aids) into a unified integrated navigation system. This integration allows cross-validation of data from different sources, significantly improving both localization precision and reliability for automated flight operations during terminal phases.
Solution Approach 2:
The system implements continuous feedback loops where localization data is constantly monitored, validated, and used to adjust navigation solutions. The cross-checking mechanism provides real-time feedback on the quality and accuracy of localization estimates, enabling the system to maintain high precision and reliability by detecting and correcting errors promptly.
2Measurement precision
If expensive navigation apparatus are installed, then navigation capability is provided, but maintenance costs increase and system complexity increases
Solution Approach 1:
The patent designs the navigation system to perform multiple functions using a shared infrastructure. The same sensor suite and processing platform support various navigation modes (GPS-based, inertial-based, ground-aid-based), reducing overall system complexity while maintaining high navigation capability across different operational scenarios.
Solution Approach 2:
The system incorporates self-diagnosis and self-validation capabilities through cross-checking mechanisms. The navigation system automatically monitors its own performance, detects anomalies, and switches between different navigation sources without external intervention, reducing maintenance requirements and operational complexity.
3Measurement precision
If traditional navigation systems are used, then basic navigation is achieved, but precision for automated procedures is insufficient
Solution Approach 1:
The patent implements a dynamic navigation system that can adapt its operating mode and data sources based on flight phase, environmental conditions, and system availability. The cross-checking mechanism dynamically adjusts the weighting and selection of navigation sources to optimize localization accuracy for automated procedures while maintaining versatility across different operational contexts.
Data Source
AI summary
A system having components coupled to an aircraft in operation processes sensor-derived data, performs a localization cross-checking procedure, and dynamically generates updated analyses of the position and orientation of the aircraft. Based on the updated analyses, the system can generate instructions for flight control of the aircraft and can update flight control instructions as new data is received and processed. The system functions to reduce the “worst-case” bounds on a localization estimate for the aircraft to a low enough level that is appropriate for completing a flight operation.
