Integrated Landing Receiver for Multi-Source Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multi-mode receivers for aircraft landing are limited by the need for separate installation of multiple landing support facilities, leading to high costs and reduced accuracy, and they fail to provide continuous landing guidance when one facility is out of order or experiences GPS jamming, resulting in increased fuel consumption and delayed landings.
Innovation Solution
An integrated landing receiver system that combines signal information processors from multiple landing support facilities (ILS, GBAS, MLS) to generate and filter integrated landing guidance information, using a weight-based equation to validate and integrate lateral deviation, vertical deviation, and distance to runway threshold data, ensuring continuous and accurate guidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple landing support facilities (ILS, GBAS, MLS) are separately installed to provide landing guidance information, then the reliability and accuracy of landing guidance is improved, but the cost and device complexity increase significantly
Solution Approach 1:
The patent combines multiple landing support facility signal processing capabilities (ILS, GBAS, MLS) into a single integrated receiver unit. The receiver includes multiple signal information processors that can simultaneously process signals from different landing support facilities, collecting and integrating their guidance information in one device rather than requiring separate receivers for each system.
Solution Approach 2:
The integrated receiver is designed to universally process signals from multiple types of landing support facilities (ILS, GBAS, MLS) through a single device. The receiver can selectively receive and process signals from any combination of these facilities, providing multi-functional capability that replaces the need for multiple dedicated receivers.
2Adaptability or versatility
If ILS is installed per runway to provide landing guidance information, then the coverage and availability of landing guidance is improved, but the cost increases due to repeated equipment installation
Solution Approach 1:
The integrated receiver can universally process signals from a single GBAS installation that serves multiple runways, eliminating the need to install separate ILS equipment at each runway. The receiver is designed to handle guidance information from any runway served by the GBAS system, providing multi-runway coverage through one device.
Solution Approach 2:
The receiver can receive and process guidance information for multiple runways through a single GBAS ground equipment installation, effectively copying the guidance capability across multiple runways without duplicating the expensive ground equipment at each location.
3Device complexity
If conventional receivers rely on a single landing support facility, then the system simplicity is maintained, but the continuous operation and reliability are reduced when the facility is out of order or experiences GPS jamming
Solution Approach 1:
The integrated receiver merges multiple signal information processors for different landing support facilities into one device, enabling it to simultaneously monitor and process signals from ILS, GBAS, and MLS. This allows the receiver to switch between facilities or combine their guidance information, ensuring continuous operation even when one facility experiences outages or GPS jamming.
Solution Approach 2:
The receiver is designed with redundant signal processing capabilities for multiple landing support facilities, providing a backup guidance information source before a failure occurs. The collector and integrator components are prepared to immediately process and integrate alternative guidance information when the primary facility becomes unavailable, cushioning against the impact of outages or jamming.

AI summary
An integrated landing receiver for landing of an aircraft and a controlling method thereof are provided, in which the integrated landing receiver includes a receiver including a plurality of signal information processors that generate landing guidance information respectively corresponding to a plurality of landing support facilities, a collector collecting the landing guidance information respectively generated at the plurality of signal information processors, and an integrator generating integrated landing guidance information by using the landing guidance information collected at the collector and outputting the result. Accordingly, when a plurality of landing support facilities are installed together at an airport, the landing guidance information provided from these landing support facilities are mixed and provided so that shortcomings that each landing supporting facility may have can be advantageously compensated, thus enabling safe and effective provision of the landing guidance information.
