CLS Launches GNSS Jamming and Spoofing Protection with its RockFLEET Assured beacon

CLS announces the launch of RockFLEET Assured, a new GNSS jamming and spoofing protection solution developed in partnership with Ground Control, a CLS Group subsidiary.

As maritime operations face increasing signal interference risks, GNSS jamming and spoofing protection is becoming essential for fleet operators worldwide.

Rising GNSS Threats in Maritime Operations

GNSS disruption is no longer theoretical. Jamming and spoofing incidents are increasing due to geopolitical tensions, criminal activity and congestion of navigation systems.

For shipowners and fleet managers, unreliable positioning creates:

• Navigational uncertainty
• Safety risks for crew and cargo
• Regulatory exposure
• Insurance and liability concerns
• Reduced trust in digital fleet data

In this context, GNSS jamming and spoofing protection is a critical component of maritime operational resilience.

A New Standard for Trusted Positioning

RockFLEET Assured delivers assured positioning (A-PNT) via Iridium PNT, enabling continuous GNSS cross-checking and authenticated position reporting.

The solution provides:

• Early detection of jamming and spoofing events
• Real-time integrity alerts
• Clear bridge display comparing assured position and GNSS status (optional)
• Two-way satellite messaging worldwide
• Configurable reporting and geofencing
• Compatibility with any NMEA 2000 device
• Optional backup battery for power-cut resilience

By combining satellite resilience with marine-grade hardware, RockFLEET Assured strengthens GNSS jamming and spoofing protection for vessels operating in high-risk areas.

Integrated Fleet Management and Cloud Connectivity

RockFLEET Assured connects seamlessly to Cloudloop Tracking, a secure browser-based fleet monitoring service. Designed with an API-first architecture, it enables integration of position and event data into customer platforms via HTTP webhooks, MQTT or REST APIs.

This ensures GNSS jamming and spoofing protection data can be embedded directly into fleet management workflows.

Strengthening Maritime Security and Operational Continuity

With RockFLEET Assured, CLS expands its maritime security portfolio, complementing its Maritime Intelligence and fleet monitoring solutions.

As regulatory scrutiny around GNSS resilience and data integrity increases, GNSS jamming and spoofing protection is moving from optional safeguard to operational necessity.

RockFLEET Assured enables shipowners and operators to maintain trusted positioning, protect fleet integrity and ensure operational continuity worldwide.
