Airborne Communication Device Automated Datalink Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current navigation systems for vehicles, such as aircraft, require significant manual effort from operators to obtain and verify position-velocity-time information, especially when external navigation aids are unavailable or unreliable, leading to increased workload and potential navigation errors.
Innovation Solution
An airborne communication device installed in vehicles receives navigation information via a datalink protocol from a ground-based communication device, reducing the need for manual operator intervention and enabling automated data transfer, discrepancy notifications, and contract-based information requests.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If navigation information is obtained through manual voice communication with air traffic controllers, then operators can request and receive PVT information, but the workload for operators and auxiliary personnel increases significantly
Solution Approach 1:
The airborne communication device automatically establishes contracts with ground-based communication devices and requests navigation information based on predefined triggers without requiring manual operator intervention. The system self-manages the entire process of initiating requests, receiving data, and updating navigation displays, thereby eliminating the need for operators to manually contact air traffic controllers for navigation information.
Solution Approach 2:
The patent replaces manual voice communication procedures with an automated digital datalink system. Instead of operators speaking to air traffic controllers through voice channels, the system uses automated data messages transmitted via datalink protocols to exchange navigation information, substituting mechanical human operations with automated electronic communication.
2Loss of information
If navigation information is transmitted via voice communication, then operators can receive PVT information from outside sources, but the digital processing and further utilization of the information becomes difficult
Solution Approach 1:
The patent replaces voice communication with automated datalink data messages that transmit navigation information in digital format. This substitution enables direct digital processing of the received information by the airborne device, allowing automatic updating of navigation displays and integration with other onboard systems without requiring manual transcription or interpretation of voice data.
Solution Approach 2:
The airborne communication device acts as an intermediary that receives datalink messages from ground-based communication devices and automatically processes this information. The device serves as a mediator between the external navigation information source and the onboard navigation systems, enabling seamless integration and further processing of the received data.
3Reliability
If operators manually contact outside sources for navigation information, then they can cross-check PVT solution integrity, but the process requires significant manual effort and time
Solution Approach 1:
The system pre-establishes contracts with ground-based communication devices before needing navigation information. These contracts define the conditions under which navigation information will be automatically requested and received, allowing the system to be prepared and ready to obtain verification data without delay when integrity checking is needed.
Solution Approach 2:
The airborne communication device automatically performs navigation information verification by establishing contracts with ground-based devices and requesting PVT data based on predefined triggers. The system self-manages the entire verification process without requiring operator intervention, continuously monitoring and cross-checking navigation solution integrity autonomously.
4Ease of operation
If datalink contracts are established for automatic navigation information transmission, then manual workload is reduced, but the system requires automated protocols and triggers for information request
Solution Approach 1:
The airborne communication device automatically manages datalink contracts with ground-based communication devices, initiating information requests based on predefined triggers such as position changes or time intervals. The system self-configures and self-manages the automated communication protocol without requiring manual setup or intervention, reducing operational complexity despite the automated nature of the system.
