Dual-use navigation software for GPS-denied environments.
ONS · Optical Navigation System · Dual-useIn active development
GPS fails in contested environments.
When GPS is denied, autonomous platforms lose absolute position. They drift, return, or are lost.
- Jamming
- Signal flooded across GNSS bands.
- Spoofing
- False coordinates injected mid-flight.
- Outage
- Mission aborted. Asset lost.
Optical terrain-matching. No satellite signal required.
A software-defined navigation layer for autonomous systems — applicable across defence and civil operations (assured PNT, logistics, BVLOS, critical infrastructure).

An independently reported optical-navigation flight test held 51.95 m accuracy over 564 km with no satellite signal.
A passive optical sensor matches observed terrain against an onboard route map to compute absolute position — independently of GPS.
No RF emission. No detectable signature. Invisible to electronic-warfare countermeasures.
Delivered as a software module for open-standard autopilot stacks.
Operational characteristics.
GPS-Independent
Operates without satellite signal — and keeps a fix through active jamming and spoofing, the conditions that down conventional autonomy.
Visual Position Fix
Matches observed terrain against an onboard route map to compute absolute position.
Zero RF Signature
No emissions for electronic-warfare countermeasures to detect or target.
Plug-In Integration
Drops into open-standard autopilot stacks. No new hardware.

Three founders. Five years working together.
45+ combined years in geospatial, navigation, and UAV systems.
Built a national-scale cartography company 2016–2023. Founded GISPOINT (United Kingdom), maker of FLY BY.
10+ years scalable software systems. Owner of ONS algorithms — map-matching, IMU fusion, and open-standard autopilot stack integration.
PhD, 30+ years navigation and UAV systems. Built and exited a prior UAV company. Chair, All-Ukrainian AeroGeodetic Association.
Together on geospatial and GIS production since 2021.
