Artificial Landmarks for Trusted Localization of Autonomous Vehicles Based on Magnetic Sensors

Area of Science:

• Robotics and Autonomous Systems
• Sensor Technology
• Navigation and Localization

Background:

• Global Navigation Satellite Systems (GNSS), radio frequency, and optical localization methods face limitations in certain environments.
• Magnetic sensors present a viable alternative for localization, particularly effective for meter-range distances.
• Artificial landmarks are crucial for autonomous systems, especially for drift correction and re-calibration.

Purpose of the Study:

• To propose an integration process for magnetic artificial landmarks using Transducer Electronic Data Sheets (TEDS).
• To enable autonomous vehicles, such as Unmanned Aerial Vehicles (UAVs), to utilize magnetic landmarks for re-orientation and re-calibration.
• To establish a standardized method for conveying essential landmark information and ensuring data integrity.

Main Methods:

• Development of an integration process based on Transducer Electronic Data Sheets (TEDS).
• Implementation of a system where magnetic landmarks provide meta-information (data formats, coordinates, calibration data, provider details).
• Certification of TEDS using digital signatures to ensure trust and data authenticity.

Main Results:

• Autonomous vehicles can autonomously decide how to use magnetic landmark information based on provided meta-information.
• The proposed TEDS integration facilitates easy adoption of magnetic landmarks by passing vehicles.
• Digital signatures on TEDS enhance the trustworthiness of magnetic landmarks and their associated data.

Conclusions:

• The TEDS-based integration offers a robust and secure method for deploying magnetic artificial landmarks.
• This approach enhances the reliability of localization for autonomous vehicles in challenging environments.
• Standardized, certified meta-information ensures that vehicles can effectively and safely utilize magnetic sensor data for navigation.
