Antispoofing Navigation Apparatus Using Dual Receiver Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current navigation systems, such as GPS, are vulnerable to spoofing attacks, which can compromise the accuracy of positioning information, particularly in critical applications like law enforcement drones and tolling systems, where manipulation of data can lead to undesirable results.
Innovation Solution
A verified antispoofing navigation apparatus is developed, comprising a primary navigation receiver and a supplemental navigation receiver, along with a verification processor, to authenticate navigation signals by combining primary and supplemental measurements, thereby detecting and mitigating spoofing attacks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single navigation receiver is used, then the device complexity is low, but the reliability of positioning information is compromised due to spoofing vulnerability
Solution Approach 1:
The navigation system is segmented into multiple independent receivers (primary and supplemental) that separately acquire and process navigation signals. This segmentation allows independent verification of positioning data, enabling spoofing detection through comparison of results from different receivers without requiring a single complex authenticated receiver.
2Reliability
If multiple navigation receivers are added for verification, then the reliability of positioning information improves, but the device complexity increases
Solution Approach 1:
Multiple navigation receivers and their processing functions are merged into a single integrated apparatus. The primary receiver, supplemental receiver, and verification processor work together as one unified system, reducing overall device complexity while maintaining the reliability benefits of multi-receiver verification.
3Measurement precision
If navigation signals are processed without verification, then the processing speed is high, but the accuracy of positioning information deteriorates due to undetected spoofing
Solution Approach 1:
The supplemental receiver performs preliminary acquisition and processing of navigation signals in parallel with the primary receiver. This preliminary action enables simultaneous verification without sequential processing, maintaining high processing speed while ensuring measurement precision through comparative analysis of independent signal acquisitions.
