ADS-B Ground Station Data Processing for Cost-Efficient Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The implementation of national Automatic Dependent Surveillance-Broadcast (ADS-B) systems is hindered by the reluctance of airlines to equip older aircraft with ADS-B avionics due to perceived lack of return on investment, and there is a need for a cost-effective solution to provide ADS-B-generated information to airlines and airports.
Innovation Solution
A low-cost ADS-B system and method that includes ground stations, a communications backbone, and graphical user interface-based flight tracking software, utilizing commercial equipment and customized processes to receive, process, and display ADS-B data in XML format over TCP/IP, offering real-time aircraft position and flight information, which can be integrated with existing ACARS systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If airlines equip older aircraft with ADS-B avionics, then real-time tracking and situational awareness are improved, but investment cost increases
Solution Approach 1:
The patent introduces ground stations as intermediary components that receive ADS-B signals from aircraft and process the data through a communications backbone. This mediator architecture allows airlines to access real-time tracking information without requiring every aircraft to have full ADS-B out capability, thereby reducing the investment burden while maintaining reliability.
Solution Approach 2:
The system creates copies of aircraft position and flight information through ground-based reception and processing. Instead of requiring direct ADS-B transmission from each aircraft to every user, the ground stations capture and replicate the data, distributing it through the network to multiple endpoints simultaneously, reducing overall system cost while maintaining data availability.
2Productivity
If ADS-B systems are deployed nationwide, then air traffic management efficiency is improved, but infrastructure cost increases
Solution Approach 1:
The patent designs the ground station system to perform multiple functions: receiving ADS-B signals, processing flight data, distributing information to various users, and integrating with existing ACARS infrastructure. This multi-functional approach allows a single infrastructure deployment to serve multiple purposes, improving air traffic management efficiency while reducing the need for separate specialized systems and lowering overall infrastructure costs.
Solution Approach 2:
The system merges ADS-B ground reception capabilities with existing ACARS (Aircraft Communications Addressing and Reporting System) infrastructure. By combining these functions into a unified platform, the patent avoids duplicating infrastructure investments and leverages existing communication backbones, thereby reducing total infrastructure cost while achieving improved air traffic management productivity.
3Loss of information
If ADS-B data is processed and distributed in real-time, then operational awareness is improved, but data processing complexity increases
Solution Approach 1:
The patent segments the data processing function across multiple ground stations distributed geographically. Each ground station independently receives and processes ADS-B data from its local area, then distributes the processed information through the communications backbone. This segmentation reduces the processing complexity at any single location while maintaining comprehensive real-time information availability through the distributed network.
Data Source
AI summary
A method and system that receives and processes ADS-B data from one or more aircraft is disclosed. The system may include one or more ground stations that receives data from one or more aircraft and converts the received aircraft ADS-B data to XML format, determines the lowest cost communication mode available, and transmits the XML data over TCP/IP to an aircraft data server. The aircraft data server receives the aircraft ADS-B data in XML format from the one or more ground stations, processes the received ADS-B data to extract aircraft data and eliminate duplicate aircraft data; determines aircraft data missing from the processed aircraft data, receives supplemental aircraft data from other sources to provide aircraft data missing from the processed aircraft data, and outputs the processed aircraft data and the received supplemental aircraft data to one or more processing devices for processing and display.
