Navigate on what lies beneath

A sensor-fusion payload for UAVs. It navigates the host aircraft without GNSS, and detects, recognizes and tracks objects.

Navigate

Independent navigation

Radar map matching and a thermal scene check confirm the fix on an FPGA system-on-chip.

SquadSense · coming soon

Sense the squad

Each payload shares its navigation confidence and health so the team can retask around a failed sensor, drone or objective.

TGS · coming soon

Terminal Guidance System

Automatic Target Detection and Recognition (ATD/ATR) for fire-and-forget applications.

Control

Human in the loop

Target decisions stay with the operator and the host system.

No pilot on board

Manned formations have pilots who coordinate and adapt in flight. UAVs have no one on board, and the ground link may be degraded in contested airspace.

The gap

Isolated aircraft

UAVs that fly as isolated aircraft cannot react together when a companion loses navigation, link or system health.

Redundancy

Shared state

If aircraft share their state over a secured data link, the team can make bounded adjustments together as conditions change.

Sheet 03SystemsIn mission order

One mission, five systems

Payload, coordination and mission software — arranged by where they work: on the ground before flight, on the aircraft, across the squad, and back at the centre.

Before flight
Module 05Nav Planner

Select a destination and waypoints, calculate and review the route, then export the flight plan.

Desktop planner Module 02 · L4RECONN.EARTH

Reference imagery converted to your sensor, plus one-shot small-object detection. Cloud or on-premise.
On the aircraft
Module 01 · L1SenzFusion

Navigation without GNSS, plus detection, recognition and tracking, in one payload.

Payload + SDK
Across the squad
Module 04 · L3SquadSense

Shares navigation confidence and payload health across the team over a secured link.

Coming soon
At the centre
Module 03 · L5OspreyVMS

Self-hosted video management: live feeds, recording, evidence storage and media encryption.
Sheet 04The stackL0 → L7

Eight layers, one operating system

L1 runs IMU motion prediction, the radar map match and the thermal scene check on an FPGA system-on-chip. L2 manages navigation updates and fallback policy; the host autopilot executes the flight plan.
