Solution Overview
Problem
Existing vehicle tracking systems are vulnerable to interference from jammers and spoofing transmitters, which disrupt satellite navigation and mobile radio signals, making it difficult to detect and track stolen vehicles effectively.
Innovation Solution
The integration of a device within the tracking system that can detect interfering transmitters, such as jammers and spoofing devices, using methods like monitoring receive parameters, integrity monitoring technologies, and sensor comparisons, along with a dedicated jamming/spoofing detector, to identify and counteract such interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If satellite navigation systems (GPS, GALILEO) are used for determining vehicle position, then global position can be accurately determined and transmitted to detecting and tracking services, but the system becomes vulnerable to interfering transmitters (jammers and spoofing transmitters) that disrupt signal reception and prevent accurate position determination
Solution Approach 1:
The patent introduces an intermediary device (detecting and tracking device with interfering transmitter detection capability) that mediates between the satellite navigation signals and the vehicle tracking system. This intermediary detects interfering transmitters and triggers alternative detection methods, thereby protecting the overall system from jamming and spoofing attacks while maintaining position determination capability through multiple pathways
Solution Approach 2:
The system performs preliminary detection of interfering transmitters by monitoring position-determining signals for inconsistencies. Before complete signal disruption occurs, the system detects the presence of jammers or spoofing transmitters and proactively switches to alternative detection methods, preventing total loss of tracking capability
2Reliability
If interfering transmitter detection capabilities are added to the tracking device, then the system can detect and respond to jammers and spoofing transmitters, but the device complexity increases
Solution Approach 1:
The patent makes the tracking device multi-functional by enabling it to perform both its original function (position determination via satellite navigation) and a new function (interfering transmitter detection). The same receiver that captures GPS/GALILEO signals also monitors for inconsistencies that indicate interfering transmitters, eliminating the need for completely separate detection hardware and reducing overall system complexity
Solution Approach 2:
The patent combines the position-determining signal reception function and the interfering transmitter detection function into a single integrated system. The receiver processes satellite navigation signals while simultaneously analyzing them for signs of interference, merging two functions into one unified device that reduces complexity compared to having separate independent systems

AI summary
A device for detecting and tracking vehicles includes a position-determining device for determining a current vehicle position, a transmitting device for transmitting the current vehicle position to a receiver via a communication channel, and a device for detecting an activated interfering transmitter and for triggering an action depending on the detection of an activated interfering transmitter.
