OHB Austria Secures Romania’s National GNSS Interference Detection System Contract
OHB Austria has successfully won the contract from ROMATSA in Romania and will deploy a nationwide 24/7 GNSS interference and spoofing detection system across 17 airports, setting a new benchmark for aviation safety!
OHB Austria GmbH has secured a contract with the Romanian Air Traffic Services Administration (ROMATSA) to deliver a nationwide GNSS monitoring and interference detection system. This project serves as an exemplary implementation of the GIDAS Stationary solution, specifically designed for continuous GNSS interference monitoring and precise analysis.
This major initiative highlights ROMATSA’s commitment to Performance-Based Navigation (PBN) and adherence to European Union guidelines, ensuring the safe and accurate use of GNSS in air traffic management. PBN emphasizes efficiency, flexibility, and safety in aviation operations by moving away from reliance on traditional ground-based navigation aids (such as VOR and NDB) to satellite navigation systems like GNSS and onboard avionics, enabling navigation according to specific performance standards. PBN defines the required navigation performance for aircraft in a designated airspace, focusing on accuracy, integrity, availability, and continuity, rather than specific navigation technologies.
In the coming months, OHB will implement the GIDAS Stationary system at 17 airports across Romania, enabling real-time GNSS signal monitoring and detection of jamming and spoofing signals. Alerts and analysis will be managed through a centralized Nationwide Airport Monitoring (NAM) interface.
Project Overview and System Functions
The deployment will be executed in three phases over 36 months:1. System Design and Threat Assessment: OHB will evaluate GNSS threats at Romanian airports.
2. Pilot Deployment: Initial deployment at three major airports.
3. Full Deployment: Complete system rollout across all 17 target airports.
Each airport will be equipped with multiple GIDAS monitoring stations that transmit data to local Monitoring Centers (MCs), which are integrated into the Nationwide Airport Monitoring (NAM) system. The NAM system provides a web-based interface for real-time GNSS monitoring, interference detection, classification, alerting, interference source localization, and statistical event analysis.
GIDAS Spoofing Detection Model
Key Features Include:
Automated Interference Detection and Classification:
The system employs advanced algorithms to detect and classify various interference types, such as Amplitude Modulated (AM) and Continuous Wave (CW) jammers, achieving high accuracy through weighted combination detection techniques.Robustness and Scalability:
GIDAS Stationary offers robust, remotely manageable components designed to counter evolving GNSS threats, with excellent scalability.User Management and Logging:
The system ensures security through role-based access control and session tracking, meeting operational standards.Post-Processing and Analysis Capabilities:
The collected data supports extensive post-event analysis, providing deep insights into interference patterns and guiding effective countermeasures to enhance aviation safety.This project underscores OHB’s expertise in GNSS interference detection, solidifying GIDAS as a key solution for secure and reliable GNSS signal monitoring in the aviation industry.
