TrustNav

TrustNav is a groundbreaking GNSS spoofing detection system that combines auxiliary inertial measurement units (IMUs) with high-integrity signal processing. This dual-monitor architecture allows TrustNav to detect spoofing at the earliest stage (capture phase), identifying subtle signal anomalies with centimeter-level sensitivity, and adapting navigational parameters in real time. Unlike conventional systems, which often miss spoofing until users are already significantly off-course, TrustNav protects against both gradual and sudden deviations.

Dual-Monitor Architecture

Combines auxiliary IMUs with high-integrity signal processing for comprehensive spoofing detection and protection.

Capture Phase Detection

Detects spoofing attacks at the earliest stage—during the capture phase—before significant navigation errors occur.

Centimeter-Level Sensitivity

Identifies subtle signal anomalies with exceptional centimeter-level sensitivity for early threat detection.

Real-Time Adaptation

Adapts navigational parameters in real time to protect against both gradual drift and sudden deviation attacks.

Gradual & Sudden Protection

Unlike conventional systems, TrustNav protects against both gradual spoofing attempts and sudden deviation attacks.

Advanced Signal Processing

High-integrity signal processing algorithms ensure reliable detection even in challenging environments.
