Maritime
We design and build our own devices, and work with a wide variety of partners to ensure that we can deliver precisely the right combination of hardware, airtime and data you need.

Track Vessels Anywhere At Sea with Satellite Connectivity

Remote Vessel
Monitoring
Monitor vessel performance, fuel usage and engine health in real time, from anywhere. Our solutions integrate with onboard sensors and control systems, enabling early anomaly detection, reducd maintenance costs, and compliance.

Emergency
SOS Readiness
Satellite-enabled connectivity provides a critical communication lifeline at sea. With built-in failover options and rugged marine-rated equipment, our solutions keep critical channels open in the face of storms, blackouts, or equipment failure.

Jamming & Spoofing Resilient Technology
Our RockBLOCK Pro STL and RockSTAR STL devices utilize the Iridium Satellite Time & Location (STL) signal, about 1,000 times stronger than GPS and GNSS. It delivers accurate location data when GPS / GNSS signals are absent or disrupted.

Global, Real-Time
Tracking
Stay connected to your fleet anywhere on Earth with our marine-ready hardware and tracking platform. Our tracking solution delivers real-time position updates, historical route data, and event tracking for complete maritime oversight.
Recommended Devices:

Vessel Tracking & Monitoring
RockSTAR offers similar functionality in a carry on/carry off format.

GPS Alternative Tracking
Unlike GPS-based signals, they delivers resilient position, navigation and timing data (PNT) even in GPS-denied or spoofed environments, making it ideal for commercial shipping, mobile asset tracking and any application where trusted positioning and timing is essential.

Who uses Ground Control for Maritime Tracking and Monitoring?

Commercial Shipping
Maritime navigation faces escalating threats from GPS spoofing and jamming, which can mislead vessels into perilous situations. RockBLOCK Pro STL addresses this challenge by delivering both GNSS and Iridium STL-derived positions.

Coast Guard
Ensure round-the-clock situational awareness with real-time vessel tracking and two-way communication. Our solution enhances operational efficiency, enabling rapid response to emergencies, unauthorized incursions, and evolving maritime threats.

Border Force
Monitor and secure maritime borders with precise tracking and instant alerts for suspicious activity. With geofencing, historical route data, and seamless communication, teams can enforce regulations and respond swiftly to unauthorized movements.

Offshore Energy Support Vessels
Maintain visibility over offshore logistics with real-time tracking and automated event monitoring. Improve coordination between vessels and shore-based operations while ensuring crew safety in remote and high-risk environments.

Coast Guard
Ensure round-the-clock situational awareness with real-time vessel tracking and two-way communication. Our solution enhances operational efficiency, enabling rapid response to emergencies, unauthorized incursions, and evolving maritime threats.

Commercial and Sport Fishing
Track and manage small fishing fleets with real-time positioning, catch-zone monitoring, and compliance reporting. Ensure crew safety with emergency alerting, while optimizing routes and fuel usage for cost efficiency.

Yacht Charter
Provide guests and fleet managers with a seamless tracking solution for vessel security and trip monitoring. Real-time updates, geofence alerts, and emergency communication features ensure safe and stress-free journeys for charter operators and their customers.
