Land-based PNT
Terra is built to perform in environments where failure is not an option — for maritime, logistics, and defense applications worldwide.

Why It Matters
Modern shipping, logistics, and defense operations depend on continuous, accurate positioning, navigation, and timing (PNT) data. GPS and GNSS signals underpin navigation, cargo tracking, port operations, fleet routing, and mission coordination.
But these signals are weak, unencrypted, and increasingly targeted. Jamming transmitters — now widely available — can blank satellite signals across large areas. Spoofing attacks can silently inject false position data, causing vessels and vehicles to navigate toward danger while believing they are on course.
The consequences range from cargo delays and financial loss to vessel groundings, collision risk, and failure of time-critical military operations. Resilient PNT is no longer a premium option — it is a baseline requirement for any serious operator.
The IMO, NATO, and the U.S. Department of Transportation have all identified resilient PNT as a critical infrastructure priority. Operators relying solely on unaided satellite navigation are exposed.
Jamming Incidents at Sea
Deliberate GPS jamming near contested maritime zones has caused vessels to lose position lock entirely, forcing manual navigation in congested or shallow waters.
Cargo Spoofing Attacks
Reported incidents in major shipping lanes have shown vessels receiving false GNSS coordinates — appearing on bridge screens as safely on route while significantly off-track.
Port & Terminal Disruption
GNSS outages near port infrastructure affect automated crane systems, vessel berthing, and cargo tracking — causing cascading delays across supply chains.
Military Navigation Denial
Modern adversaries deploy portable electronic warfare systems capable of denying or corrupting GNSS signals over wide areas, directly impairing situational awareness and mission execution.
Industries Served
From deep-sea cargo vessels to coastal patrol craft, our systems deliver continuous, reliable position and timing data across ocean passages, congested ports, and narrow waterways — under any weather condition.
Commercial Shipping · Port Authority · Coastguard
Our hardware is designed to sustain accurate positioning when conventional satellite signals are unavailable, jammed, or spoofed. Purpose-built for operational environments where mission continuity is non-negotiable.
Naval · Ground Vehicles · Forward Operating BasesTechnology
Terra uses maintains accurate, trustworthy PNT data in environments where satellite signals alone cannot be relied upon. The result is a system that is operationally transparent — always on, always accurate — regardless of the electromagnetic environment.
Terra receivers deliver accurate position and timing data through active jamming environments. By combining multiple independent signal sources and applying adaptive signal processing, the system maintains lock even when broadband or spot jammers are present at close range.
Unlike conventional GNSS receivers that fail silently under jamming, Terra hardware alerts the operator to interference conditions while continuing to output valid data through alternative paths.
Interference Detection · Continuous OutputOur hardware uses cross-verification across independent signal sources to detect and reject spoofed position data. If any source reports coordinates inconsistent with the independently derived solution, it is flagged and excluded automatically — before bad data reaches your navigation system.
Operators receive a clear authenticity status on every position fix. A spoofed signal cannot silently corrupt the output.
Cross-Source Validation · Tamper AlertTerra hardware is engineered for fast field installation. Compact form factors, standardized connectors, and a pre-configured software stack mean units can be operational within minutes — no specialist commissioning required.
Rapid Cold Start · Plug-and-Play IntegrationRather than depending on a single signal type, Terra receivers simultaneously processes multiple independent sources. These are continuously weighted and fused into a single, high-confidence position output.
Multi-Source Fusion · No Single Point of FailureWhether you're integrating into a new platform or replacing legacy equipment, our engineering team can support your program from specification to installation.
