Distributed sensors
Complementary modalities positioned around the asset, each contributing partial observations rather than a single point of truth.
Research and prototype development
Earlier awareness. More time to act.
HOSN Advanced Systems is developing distributed sensing and local intelligence to help protect critical infrastructure from low-altitude aerial threats.
Founded in the United Arab Emirates
Concept film
A clearer view of the Sentinel concept
A cinematic scenario: low-flying aerial threats are picked up by AI edge nodes, tracked in the HOSN command software, and met by a guardian drone using a non-kinetic response. Illustrative only, not a performance demonstration.
01 — The problem
Small, slow and low is hard to separate from everyday clutter.
Low-altitude aerial objects share the same crowded airspace as birds, weather, terrain reflections and routine industrial activity. A single sensor sees a fragment of the picture, and fragments create doubt.
Infrastructure operators rarely need more raw alerts. They need earlier, dependable awareness — enough context to decide whether something deserves attention, and enough time to follow their own procedures.
Cluttered background
Terrain, sea state and site activity generate returns that resemble small aerial objects.
Fragmented observations
Independent sensors report separately, leaving operators to reconcile conflicting views.
Late, thin warnings
An alert without supporting evidence is difficult to act on with confidence.
02 — HOSN Sentinel
A proposed sensing and early-warning platform.
Sentinel is our concept for connecting complementary sensors around a site, correlating their observations where they are produced, and presenting one reviewed operational picture to the people responsible for the facility.
The intent is a layered relationship: distributed sensors contribute partial observations, local processing assembles them into tracks with traceable evidence, and an on-premises interface keeps the decision with the operator.
Local processing
Correlation and fusion intended to run on site, so awareness does not depend on an external connection.
Shared operational picture
One reviewed view with supporting evidence, designed for the operator's existing procedures.
Sentinel is in research and prototype development. Nothing on this page describes demonstrated field performance.
03 — How the concept works
Select a component to see its intended role.
A high-level view of the intended architecture. Deployment layouts, coordinates and engineering specifications are deliberately not shown.
Passive sensing
Intended role
Listens for signals of interest in the environment to raise early, low-cost attention without transmitting.
Limitations
Ineffective against objects that emit nothing, and sensitive to local signal congestion.
04 — Engineering priorities
Design priorities we hold ourselves to.
These are the properties we are engineering for, and how we intend to evidence them.
- Cloud-independent operation
- Detection, correlation and warning are designed to continue when external connectivity is unavailable.
- Modular integration
- Sensors and interfaces are treated as replaceable modules with documented interfaces.
- Evidence traceability
- Every track should be explainable: which observations contributed, when, and with what uncertainty.
- Maintainability
- Field serviceability, diagnostics and clear failure states are part of the design, not an afterthought.
- Measurable performance
- Claims follow measurement. Test conditions and methods are recorded alongside results.

05 — Research and validation
A phased path from laboratory to pilot.
Each phase has to produce evidence before the next one begins.
01 · Completed
Laboratory assessment
Component characterisation and recorded-data experiments to understand what each modality can and cannot contribute.
02 · In progress
Controlled trials
Instrumented trials in controlled conditions, with documented methods and repeatable measurement.
03 · Planned
Integrated prototype
End-to-end prototype linking sensing, edge fusion and the command interface on one site.
04 · Planned
Customer pilot
Supervised pilot with an infrastructure operator, evaluated against agreed criteria.
Research target, not demonstrated performance: a 30–40 km protected-zone warning objective for the concept as a whole. This is not a sensor range figure and has not been validated.
06 — Applications
Where earlier awareness could matter.
Potential use cases under study. We do not claim deployments, customers or operational results.
Energy facilities
Refineries, storage and generation sites where a wide perimeter and continuous operation make early awareness valuable.
Ports and maritime terminals
Open approaches, dense activity and high-value cargo movement across large open areas.
Logistics centres
Distribution hubs where uninterrupted throughput depends on predictable, low-disruption operations.
Industrial sites
Manufacturing and processing plants with sensitive processes and strict safety procedures.
Utilities and transport corridors
Substations, water infrastructure and transport links distributed across long, thin footprints.
Campuses and mixed estates
Large managed estates that combine public access with operationally sensitive areas.
07 — About HOSN
A UAE engineering company building credible technology through disciplined research.
HOSN Advanced Systems — حصن للأنظمة المتقدمة — takes its name from the Arabic word for fortress. We are based in the United Arab Emirates and focused on one problem: giving infrastructure operators earlier, better-evidenced awareness of low-altitude aerial activity.
Our approach is evidence-led. We publish what we can support, label research targets as targets, and keep the operator's judgement at the centre of the system. Team profiles will be added once approved names, biographies and photographs are available.
Founded in the United Arab Emirates
HOSN Advanced Systems is an independent company. Nothing on this website implies government endorsement or an existing customer relationship.
