TrustPoint has secured a $4 million Tactical Funding Increase (TACFI) contract from United States Space Force to demonstrate a GPS-independent positioning, navigation, and timing (PNT) system designed for defense and commercial applications.
The award was issued through SpaceWERX and jointly funded by the Small Business Innovation Research (SBIR) program and the Commercial Space Office (COMSO). The project will support an end-to-end demonstration of TrustPoint’s resilient navigation architecture aimed at operating in environments where traditional GPS signals may be disrupted or unavailable.
Under the contract, TrustPoint will design, deploy, and operate a fully integrated PNT network consisting of four satellites and four ground stations. The program will include live trilateration demonstrations across multiple space and ground assets, operational navigation services, and advanced receiver technologies.
The company said the system is being developed with an accelerated deployment timeline, with initial infrastructure expected to be operational within 12 months. TrustPoint added that the architecture is designed to scale efficiently into larger satellite constellations while maintaining affordability, operational flexibility, and capital efficiency.
Patrick Shannon said the project is intended to demonstrate that resilient navigation systems can be developed without relying on large-scale, high-cost satellite constellations. He noted that the initiative will validate TrustPoint’s GPS-independent capabilities while highlighting the company’s approach to delivering operational PNT services with lower infrastructure costs.
The program will also validate a software-defined navigation architecture capable of dynamically reconfiguring services in contested, degraded, or denied operating environments. TrustPoint said the capability is designed to support both military and commercial users requiring reliable positioning and timing services in GPS-challenged conditions.
The company has previously demonstrated several C-band navigation milestones, including real-time reception of C-band GNSS signals and broadcast-based ground-to-space C-band PNT demonstrations. The latest TACFI program is expected to build on those developments while supporting broader national security objectives and future commercial navigation services.
TrustPoint said the project establishes a scalable foundation for next-generation resilient navigation systems as demand grows for secure alternatives to conventional satellite-based positioning technologies.
