Small apparent size
Useful image detail must be recovered from a limited target signature.

A view built for
early awareness.
ARGUS is an AI-assisted electro-optical observation concept for building early awareness of small unmanned aircraft in complex, low-altitude environments.

OHMIRIS / ARGUS01 / THE OBSERVATION GAP
SMALL UAS.
OUTSIZED CONSEQUENCES.
Low-cost, one-way unmanned aircraft can create disproportionate risk for high-value assets and critical infrastructure. Their size, low-altitude profiles, movement and changing backgrounds can make observation difficult for any single sensing layer.
Complex backgrounds
Sky, terrain, infrastructure and weather change the visual scene continuously.
Time-critical decisions
Information must arrive with context that supports a timely human decision.
02 / INFORMATION FLOW
FROM SCENE TO
DECISION-READY CONTEXT.
ARGUS is designed as a supporting observation layer. It connects electro-optical sensing with a purpose-trained situational-awareness model and an operator-facing presentation — then provides the assessed context to authorised response and command interfaces.

04ConnectAuthorised command and response interfaces
ARGUS supports detection, assessment and hand-off. Response decisions remain with the authorised operator and connected systems.
03 / EVOLUTION PATH
MULTI-SENSOR
AIRSPACE AWARENESS.
The long-term ARGUS direction is not more sensors for their own sake. It is a disciplined fusion architecture: each sensing layer contributes a distinct piece of context, while the operator retains authority over assessment and response.
Development themes — not current product specificationsEO
FOUNDATION
Electro-optical confirmation
Visible and other optical observation channels provide the visual track, scene context and human-verifiable evidence at the centre of the ARGUS concept.
AC
FUTURE SENSING LAYER
Passive acoustic cues
Research into rotor and propulsion sound patterns may add environmental cues where acoustic conditions permit. Acoustic information is intended as a supporting signal, not a standalone identification claim.
RF
FUTURE SENSING LAYER
Passive spectrum awareness
Where lawful and authorised, passive monitoring of the surrounding radio environment may provide time and direction cues for fusion with visual observation. The objective is situational context — not interception of communications content.
FX
FUSION LAYER
Contextual sensor fusion
A purpose-trained situational-awareness layer can correlate time, direction, scene and sensor confidence into one operator-readable picture — with traceability and human authorisation built into the workflow.

CONCEPTUAL ARCHITECTURE
Illustrative architecture for technical communication. Component placement and interfaces remain subject to programme validation.
INTEGRATION / ILLUSTRATIVE CONCEPT
PART OF THE
DEFENCE CHAIN.
ARGUS is intended to contribute a clear visual track and assessed location context to the wider counter-UAS architecture. It does not replace radar, command-and-control or response systems; it adds an electro-optical layer where visual confirmation matters.
ARGUS is being developed to help operators establish, assess and maintain a visual track of small unmanned aircraft where apparent size, motion and background complicate observation.
Detection support
Optical observation adds a complementary source of scene information where detectability varies with environment and geometry.
Assessment support
Visual context helps an operator distinguish motion, object characteristics and the surrounding scene.
Track continuity
Stabilised observation and considered workflow design support persistent assessment over time.
ENGINEERING NOTE
The lower airspace is an information problem.
Small unmanned aircraft can present a difficult observation task: apparent size is limited, backgrounds are complex and conditions change rapidly. ARGUS is a development programme focused on combining optical observation, stabilised control and clear operator presentation into one coherent system concept.
A practical framework
Object-to-background contrast
Whether an object is visually separable depends on background, illumination, spectral response and atmospheric transmission.
Angular sampling
A target must occupy useful image detail; field of view, focal length and pixel pitch are considered together.
Operator confidence
The intended outcome is an assessable observation with explicit system context, not an unsupported automated conclusion.
