GNSS Security for Connected Vehicles
Position is a critical safety input. We secure it against spoofing, jamming, and degradation — from signal authentication to multi-sensor fusion.

Galileo OSNMA Integration
Open Service Navigation Message Authentication — the European answer to GNSS spoofing. We implement OSNMA validation in your receiver stack, test against spoofing scenarios, and ensure compliance with the Galileo OS-SIS-ICD. From receiver evaluation to production integration.
Anti-Spoofing & Anti-Jamming
Threat assessment for your GNSS-dependent systems. Spoofing detection algorithms, signal-level anomaly detection, multi-constellation cross-checks. Jamming resilience through controlled radiation pattern antennas, adaptive filtering, and frequency hopping strategies.
RTK & CORS Infrastructure
High-accuracy positioning infrastructure: RTK and PPP-RTK service design, CORS station deployment and monitoring, NTRIP caster configuration. Designs can leverage 795+ European CORS reference stations for redundant coverage. Sub-centimeter accuracy with integrity guarantees.
Sensor Fusion & Dead Reckoning
When GNSS is denied or degraded, the vehicle must keep navigating. We design IMU+GNSS+odometry fusion architectures for dead reckoning. Extended Kalman filters, error modeling, drift characterization. Validated against real-world jamming scenarios.
Frequently Asked Questions
OSNMA (Open Service Navigation Message Authentication) is Galileo's mechanism for authenticating navigation messages. It allows receivers to verify that positioning signals genuinely come from Galileo satellites, not from a spoofer. It became operational in 2023 and is the first civilian GNSS authentication service worldwide.
Yes. Documented cases include spoofing attacks on shipping vessels in the Black Sea (2017), Tesla navigation manipulation demonstrations, and drone hijacking via GPS spoofing. For autonomous vehicles, a spoofed position could cause lane departure, wrong-way driving, or geofence violations. Attack equipment is increasingly accessible.
RTK (Real-Time Kinematic) achieves centimeter-level accuracy (1-3 cm horizontal) when connected to a nearby reference station. PPP-RTK extends this globally without a local base station. Our CORS infrastructure designs leverage 795+ European reference stations for redundant, always-available high-accuracy positioning.
Sensor fusion combines GNSS with inertial measurement units (IMU), wheel odometry, and visual odometry to maintain positioning during GNSS outages. Using Extended Kalman Filters, the system can maintain positioning during brief GNSS outages, giving the vehicle time to reach a safe state or find alternative positioning sources.
