Preparations for Galileo PRS in Poland.

Area of Science:

• Navigation systems security
• Satellite technology
• Geospatial intelligence

Background:

• Global Navigation Satellite System (GNSS) faces escalating security threats from interference and attacks, exacerbated by geopolitical tensions in 2022.
• Existing GNSS open services are vulnerable, necessitating more robust solutions for critical applications.
• The coexistence of Public Regulated Service (PRS) signals with amateur radio services presents regulatory and technical challenges.

Purpose of the Study:

• To analyze the increasing security risks to GNSS.
• To introduce the Galileo Public Regulated Service (PRS) as a more secure alternative.
• To discuss the implementation, regulatory aspects, and technical challenges of PRS, including its coexistence with other services.

Main Methods:

• Technical description of Galileo PRS.
• Analysis of implementation strategies within the European Union.
• Review of regulatory frameworks and the role of governmental authorities.
• Examination of signal coexistence issues with amateur services.
• Presentation of Polish R&D contributions, including measurement stations and threat detection systems.

Main Results:

• Galileo PRS offers enhanced resilience against jamming and spoofing compared to open GNSS services.
• Controversies exist regarding PRS signal coexistence with amateur radio services in Europe.
• Polish initiatives include participation in R&D projects, a dedicated measurement station, and a conceptual threat detection system for Galileo PRS.

Conclusions:

• The Galileo PRS is a critical development for enhancing GNSS security and reliability.
• Addressing signal coexistence and regulatory aspects is crucial for successful PRS deployment.
• Polish contributions are significant in advancing Galileo PRS technology and security testing.
