Core positioning technology
Omnisense provides a radio-based terrestrial positioning architecture designed for accuracy and scalable deployment across autonomous and GNSS-resilient systems.
Position is derived from direct radio measurements between distributed fixed nodes and mobile devices, enabling operation where GNSS is degraded or unavailable.
The system enables predictable positioning performance across both GNSS-supported and GNSS-degraded environments.

Radio-based positioning architecture
The architecture combines distributed fixed nodes with mobile tags to enable precise ranging and position estimation within defined operational environments. Position is derived from terrestrial radio measurements rather than satellite-based signals, allowing operation independent of GNSS.
Current deployments utilise ultra-wideband (UWB) to deliver high-precision ranging performance. The underlying techniques and intellectual property are frequency-agnostic, enabling adaptation across radio bands as regulatory frameworks and operational requirements evolve.
Terrestrial positioning maintains operation when GNSS is degraded or unavailable.
GNSS Resilience
Ground-based ranging enables stable positioning performance in environments where GNSS is unreliable, degraded, or unavailable.
Rather than replacing GNSS, the system provides a complementary positioning layer that maintains operational continuity and supports reliable navigation decisions in challenging conditions.

GNSS-Degraded Performance
System performance has been validated through field-based trials, including GNSS-disabled scenarios, demonstrating stable positioning behaviour under degraded conditions.
Performance remained stable and bounded under GNSS-disabled conditions.
Extended-Range Capability
Recent hardware and system-level developments have significantly increased operational range while maintaining ranging accuracy. This reduces required infrastructure density and improves deployment economics without compromising performance.
Extended-range capability has been validated through autonomous navigation trials, including GNSS-disabled landing scenarios.
Architectural Principles
Infrastructure efficiency
Extended-range capability reduces required fixed node density, lowering deployment complexity and cost.
Frequency-agnostic foundation
Core positioning methods are not constrained to a single radio band, supporting future adaptation across spectrum allocations and regulatory environments.
Integration-ready architecture
Designed to operate independently or integrate with GNSS and complementary sensing systems to enhance navigation resilience.

Hardware and System-Level Development
System architecture refinement has been informed by research collaborations, autonomous navigation projects, and real-world operational deployments.
Iterative hardware development supports extended-range performance, integration flexibility, and scalable deployment across diverse environments.
Positioning beyond and alongside GNSS
While GNSS provides global coverage, performance can degrade in obstructed, indoor, or interference-prone environments.
Omnisense technology provides a complementary terrestrial positioning layer that can operate independently or integrate within broader navigation stacks to enhance overall system resilience.
