General Dynamics GPS Source to Prototype NorthStar PNT Hub for U.S. Army

General Dynamics Mission Systems announced that Project Manager, Positioning, Navigation and Timing (PM PNT) entered into an agreement for the prototyping, demonstration, and testing of the NorthStar PNT Hub. The three-year contract, valued at $17 million, was established through an Other Transaction Agreement (OTA) with CMG Networks on behalf of the Consortium for Command and Communications in Cyberspace (C5).

Modular System Architecture
The NorthStar PNT Hub is a modular Assured Positioning, Navigation and Timing (APNT) system designed for GPS-contested environments. The unit is engineered to occupy the same physical space as existing Defense Advanced GPS Receiver (DAGR) units to facilitate rapid platform integration across Army vehicle fleets.

The system features a scalable architecture with industry-standard interfaces, allowing it to support various independent sensors, RF sources, and antennas. This modular design is intended to permit user-level maintenance and configuration across different capability tiers, supporting future upgrades and long-term adaptability.

Resiliency and Integrity Detection
To maintain timing and positioning for Multi-Domain Operations, the system integrates multiple PNT sources. It employs spoofing and integrity detection techniques to identify and mitigate interference. Rachel Oberc, vice president for Network & Communication Systems at General Dynamics Mission Systems, stated that the architecture enables rapid upgrades to provide assured timing and positioning in evolving operational environments.




Additional Context
In modern electronic warfare, the reliance on Global Positioning System (GPS) signals represents a significant vulnerability, as these low-power satellite signals are susceptible to jamming (denial of service) and spoofing (transmission of false data). Assured Positioning, Navigation, and Timing (APNT) is a technical framework used by defense agencies to ensure continuous operational capability when GPS is unavailable or compromised.

The shift toward modular, open-architecture systems like the NorthStar PNT Hub reflects a broader military strategy to avoid proprietary "black box" hardware. By using standardized interfaces, the military can integrate diverse sensors—such as inertial measurement units (IMUs), vision-based navigation, or signals of opportunity—without redesigning the entire vehicle integration. Furthermore, utilizing Other Transaction Agreements (OTAs) allows for a more flexible and rapid acquisition process compared to traditional federal contracts, specifically designed to attract non-traditional defense contractors and speed up the prototyping of emerging technologies.
