A-PNT: Navigation Beyond GPS
Our 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 handheld to embedded, our A-PNT solutions are built to withstand harsh conditions. Whether mounted in a vehicle, installed on unmanned equipment, or carried on foot, they deliver field-proven performance backed by over 20 years of satellite tracking experience.
Flexible integration options
RockBLOCK APNT supports RS-232, RS-485, and USB-C interfaces for easy integration into existing systems, with Bluetooth 5.0 available for local configuration. RockSTAR APNT offers a standalone solution with built-in display, keyboard, and two-way satellite messaging.
Secure, verifiable, and ready now
Using cryptographic techniques for signal authentication, our A-PNT solutions ensure trustworthy data in high risk environments. Both RockSTAR APNT and RockBLOCK APNT devices are rugged, proven, and ready to deliver assured PNT when GPS can’t.
Our A-PNT Devices
RockBLOCK APNT offers the same resilient PNT capabilities in a compact, fixed-mount form, perfect for vehicles, unmanned systems, or field equipment. Ruggedized and waterproof, it’s easily integrated via serial or USB-C, with Bluetooth available for local config.

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
RockSTAR APNT and RockBLOCK APNT devices are 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.
