TrustPoint, a startup developing a commercial Global Navigation Satellite System (GNSS) service, has selected Bulgarian spacecraft manufacturer EnduroSat to construct its planned 40-satellite constellation. The partnership marks a significant step for TrustPoint as it transitions from technology demonstration to full-scale operational deployment.
What Happened
Under the agreement, EnduroSat will build and deliver the satellites in three separate batches. The initial set of spacecraft is scheduled to launch no earlier than 2027. TrustPoint CEO Patrick Shannon stated that, contingent on supply chain stability and launch availability, the company expects the entire constellation to be operational within 24 to 30 months of the first launch.
This contract follows a series of successful technology demonstrations for TrustPoint. The company previously launched two early tech-demo satellites in 2023 and a full tech-stack demonstration in 2025. These flights validated the technical capabilities of TrustPoint’s proposed service, including the first real-time demonstration of a C-band GNSS signal.
TrustPoint’s architecture relies on satellites operating in Low Earth Orbit (LEO), distinct from the Medium Earth Orbit (MEO) used by public GPS systems. The company utilizes C-band frequencies rather than the L-band frequencies typical of traditional GNSS services. Shannon explained that C-band signals are less affected by ionospheric interference, a common source of GPS errors that can be exacerbated by space weather and solar storms. Additionally, the use of C-band presents fewer regulatory hurdles compared to the congested L-band spectrum, allowing TrustPoint to avoid lengthy international negotiations for usage rights.
Why It Matters
The selection of EnduroSat and the specific technical choices made by TrustPoint highlight a growing trend in the commercial space sector: the development of specialized, cost-effective alternatives to government-operated navigation systems. By leveraging C-band and LEO, TrustPoint aims to offer a GPS-independent Positioning, Navigation, and Timing (PNT) solution that balances performance with economic viability. This move adds to the competitive landscape alongside established LEO players like SpaceX’s Starlink, which has also expanded its positioning and timing capabilities.
Cost efficiency is central to TrustPoint’s business model. Shannon noted that the decision to use C-band and operate in LEO allows for significantly smaller satellites, weighing approximately 10 kg each, compared to the multi-ton public GPS satellites. This reduction in size lowers both production and launch costs, enabling the company to fit more satellites into standard launch fairings. Shannon emphasized that the company’s founding principle is to avoid building a billion-dollar constellation, targeting a delivered cost per satellite in the low six figures.
For the broader industry, this move demonstrates how private entities can circumvent some of the technical and regulatory limitations of legacy systems. The reduced ionospheric impact of C-band signals promises greater reliability for users, particularly in regions prone to severe space weather, while the lower regulatory burden may accelerate deployment timelines for private GNSS networks.
The Bottom Line
TrustPoint’s partnership with EnduroSat signifies the company’s graduation from testing to full-fledged operations. With a target of deploying a 40-satellite constellation by the late 2020s, TrustPoint is betting that a smaller, cheaper, and technically distinct GNSS network can compete with free public GPS by offering higher reliability and easier regulatory approval.
