UAV Positioning Integrity Detection Using Nearby Aircraft Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Unmanned aerial vehicles (UAVs) can inadvertently enter flight restriction zones due to hacked or interfered positioning devices, posing a risk to flight safety as they may output fake positions, leading to potential accidents.
Innovation Solution
A method involving a control terminal and an UAV that obtain position information from a positioning device and flight state information from surrounding aircrafts, using this data to detect if the positioning device has been cracked or interfered with, and adjust the UAV's flight state to prevent entry into restricted zones.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the UAV relies on positioning device output to determine flight permission and height, then operation efficiency is improved, but vulnerability to hacking increases, worsening security
Solution Approach 1:
The patent applies preliminary action by performing verification of position information authenticity before flight permission is granted. The aircraft detection device pre-checks the reliability of the positioning device by comparing detected aircraft positions with reported positions. Only after confirming the positioning device is operating normally does the system permit flight operations, preventing hacked positioning data from compromising security.
Solution Approach 2:
The aircraft detection device serves as an intermediary verification layer that independently validates position information without interfering with the efficiency of normal flight operations. When the positioning device is verified as reliable, the system operates efficiently using its output; when verification fails, security measures are triggered without affecting the underlying efficient operation capability.
2Reliability
If the system uses aircraft detection device to verify positioning device authenticity, then positioning reliability is improved, but device complexity increases
Solution Approach 1:
The aircraft detection device is designed with multi-functionality, serving both as a primary aircraft detection tool for flight safety and as a verification mechanism for positioning device authenticity. By making the detection device universal, the patent avoids adding separate dedicated verification equipment, thereby improving positioning reliability while minimizing the increase in overall system complexity.
