Jamming-Resistant Vehicle Tracking via Base Station Triangulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle tracking systems fail to locate a stolen vehicle after communication jamming occurs, as they lose contact with the vehicle's GPS and cellular signals, leading to ineffective tracking and recovery.
Innovation Solution
A system that detects jamming and uses location determination signals transmitted from a communication and jamming detection device to an external location determination device, employing triangulation and signal power analysis to determine the vehicle's location, even when communications are disrupted, and alerts security providers for recovery actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If GPS and cellular communication systems are used for vehicle tracking, then vehicle location can be determined accurately, but the system becomes vulnerable to jamming attacks that block signals
Solution Approach 1:
The patent introduces base stations as intermediary devices that receive location determination signals directly from the vehicle. These base stations act as mediators between the vehicle and the tracking system, allowing location determination through signal triangulation rather than relying solely on GPS satellites or cellular networks that are vulnerable to jamming.
Solution Approach 2:
The patent replaces the GPS-based electronic positioning system with a radio signal triangulation system using base stations. This substitution involves using terrestrial radio wave propagation and time difference of arrival measurements instead of satellite-based positioning, making the system more resistant to jamming attacks.
2Duration of action of stationary object
If traditional tracking systems rely on continuous GPS and cellular communication, then location data can be maintained, but tracking fails completely when jamming occurs
Solution Approach 1:
The patent implements prior cushioning by establishing multiple communication paths and backup mechanisms before jamming occurs. The system is pre-configured with base stations positioned to provide triangulation capabilities, and the vehicle is equipped with multiple transceivers that can switch between different communication channels and protocols when jamming is detected.
Solution Approach 2:
The patent applies dynamics by making the tracking system adaptive and flexible in response to jamming conditions. The vehicle's transceivers dynamically switch between GPS, cellular, and direct base station communication modes. The system adjusts its operational characteristics based on the detected jamming level, transitioning from normal operation to emergency tracking protocols.
3Reliability
If multiple transceivers and communication protocols are implemented to resist jamming, then tracking reliability improves, but device complexity increases
Solution Approach 1:
The patent implements universality by designing the vehicle's tracking device with multi-functional transceivers that can operate with multiple communication protocols (GPS, cellular, direct base station signals). These universal transceivers perform multiple functions including normal communication, jamming detection, and emergency location determination, reducing the need for separate specialized devices.
Solution Approach 2:
The patent merges multiple tracking functions into a single integrated system. The vehicle's tracking device combines GPS reception, cellular communication, and direct base station signal transmission capabilities in one unit. The base stations themselves are merged with existing cellular infrastructure, reducing overall system complexity while maintaining multiple communication paths.
Data Source
AI summary
Communications are established and conducted between a communication and jamming detection at a vehicle and a base station. At the communication and jamming detection device, a determination is made as to when jamming of the communications between the communication and jamming detection device and the base station is occurring. When jamming is determined to be occurring, at least one location determination signal is transmitted from the communication and jamming detection device to at least one external tracking device. At the at least one external location determination device, the at least one location determination signal is received from the communication and jamming detection device. The location of the communication and jamming detection device at the vehicle is determined from the at least one location determination signal.
