A-PNT: Positioning Beyond GPS
Our A-PNT solutions leverage Iridium PNT, space-based signals up to 1,000 x more powerful than GNSS / GPS, making them highly resistant to jamming and spoofing.
Assured Positioning, Navigation and Timing (A-PNT) Key Features
Assured PNT when GPS isn’t an option
Our devices use Iridium PNT signals – up to 1000 x stronger than GPS and resistant to spoofing or jamming – providing verified position, navigation, and timing even in GPS-denied environments. This ensures dependable situational awareness and timing continuity.
Designed for real world deployment
From compact above-deck terminals to embedded integration formats, our A-PNT solutions are built for real operations and supported by Ground Control’s long experience delivering satellite tracking and messaging systems.
Flexible integration options
Choose the right deployment model: a self-contained above-deck maritime terminal for retrofit, or an embedded A-PNT integration for platforms and systems. Manage configuration remotely, and deliver position plus integrity events to your software via APIs.
Secure, verifiable, and ready now
Our A-PNT devices use Iridium PNT with cryptographic authentication to provide a trusted position source when GNSS is spoofed or jammed. Integrity reporting and event logs help teams spot anomalies when GPS is untrusted.
Hardware Options
Merchant Shipping
Marine-grade and simple to install, RockFLEET Assured requires no below-deck electronics unless you choose the optional bridge view. Configuration is managed OTA, with commissioning via a Bluetooth LE app, plus APIs for integrating vessel location and events.
Land Vehicles, UAVs & Autonomous Systems
Ruggedized and waterproof, it’s easily integrated via serial or USB-C, with Bluetooth available for local config. It also supports Cloudloop integration.

GNSS ResilienceControl Your Airtime, Your Way
With Cloudloop Subscription Manager, you’re in full control of your airtime. Start, stop, pause, or reassign subscriptions in seconds, with no need for support tickets or long term commitments. This flexibility keeps costs down and operations agile, especially in dynamic or unpredictable deployments.
See Your Devices in Real Time
Cloudloop Tracking gives you full visibility over your APNT devices, with real-time updates and a visual map interface. Whether GPS is available or not, you can monitor movements, set geofences, and respond faster to critical events, all from a secure browser-based platform.
Simplified, Secure Data Flow
Cloudloop Data ensures your location, timing, and status messages are delivered reliably, with built-in cryptographic verification. You can route messages to multiple destinations, translate formats, and keep sensitive data under your control, without writing custom infrastructure.
Configure Remotely, Deploy Confidently
Using Cloudloop Device Manager, you can push firmware updates, change settings, and monitor diagnostics remotely. That means less time in the field, faster rollouts, and more resilient devices; all essential for units deployed in hard to reach or contested environments.
Scalable Platform, Proven in the Field
Cloudloop supports thousands of devices across defence, aviation, logistics, and energy. Its API-first design and flexible architecture make it easy to integrate with your existing systems and scale as your needs evolve, from a few test units to full operational fleets.
Built for GNSS-Contested Operations
RockBLOCK APNT is engineered to operate in GPS-denied environments. Cloudloop supports this capability by reliably handling and visualizing PNT data, giving you clarity and confidence, even when traditional signals are compromised.
