Aircraft GPS Compromise Mapping from ADS-B Position Anomalies
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aircraft GPS systems may malfunction due to interference, jamming, or spoofing, and existing web-based platforms provide delayed and incomplete data, necessitating a real-time, non-web-based system to identify GPS-compromised locations.
Innovation Solution
A method that continuously receives data from other aircrafts via ADS-B signals, identifies anomalies indicative of GPS malfunctions, and creates a digital map to alert pilots of potential GPS failures, allowing for real-time adjustments to flight paths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If web-based platforms are used to provide GPS interference data, then information about GPS issues can be obtained, but the system requires internet connection and has time lag in detecting GPS issues
Solution Approach 1:
The patent uses other aircraft as intermediary carriers to transmit GPS anomaly data. Instead of relying on web-based platforms requiring internet connection, the system collects positional information from multiple aircraft that have experienced GPS interference, and these aircraft themselves serve as the communication medium to share data with the first aircraft, eliminating the need for internet infrastructure.
Solution Approach 2:
The system implements real-time feedback by continuously receiving positional information from other aircraft and immediately processing this data to identify GPS anomalies. The first aircraft receives ongoing updates about GPS interference locations from multiple sources, allowing the pilot to adjust the flight path in real-time based on current anomaly data rather than historical web-based information.
2Loss of information
If web-based platforms are used to detect GPS issues, then GPS interference information can be accessed, but there is a time lag in identifying GPS issues before the aircraft reaches those locations
Solution Approach 1:
The system performs preliminary action by collecting and analyzing GPS anomaly data from multiple aircraft before the first aircraft reaches the problematic locations. By continuously monitoring positional information from other aircraft that have already encountered GPS interference, the system identifies anomaly patterns in advance, allowing the pilot to proactively adjust the flight path before entering GPS-compromised areas.
Solution Approach 2:
The system maintains continuous action by constantly receiving positional information from multiple aircraft throughout the flight. Rather than periodic updates, the system continuously processes data from other aircraft to maintain real-time awareness of GPS anomaly locations, ensuring the pilot always has current information for navigation decisions.
3Loss of information
If web-based platforms are used, then GPS interference data from certain areas can be obtained, but data may not be available for areas the aircraft is about to fly into if only certain flight data is available
Solution Approach 1:
The system achieves universality by collecting GPS anomaly data from multiple aircraft operating in different locations and flight paths. Instead of relying on a single web-based platform with limited data coverage, the system aggregates positional information from numerous aircraft sources, creating a comprehensive dataset that covers diverse geographic areas and flight routes, ensuring data availability for the first aircraft's upcoming path.
Solution Approach 2:
The system transitions from two-dimensional web-based platform data to three-dimensional spatial data by utilizing positional information from multiple aircraft in different spatial locations. This multi-dimensional approach allows the system to construct a comprehensive spatial map of GPS anomalies across various altitudes and geographic coordinates, providing coverage for areas the first aircraft intends to fly into.

AI summary
A system and a method (300) continuously receives (302) data at a first aircraft (402) from a second aircraft (404) while the first and second aircrafts are traveling. The data includes at least some positional information of the second aircraft. One or more anomalies in the data are identified (306) that are indicative of one or more geographic locations where a global positioning system (GPS) of the second aircraft was compromised. A digital map (500) is automatically created (308) that indicates the one or more geographic locations associated with the one or more anomalies that are identified in the data.
