Drone Alert Service (DAS)
Entry-level CUAS protection, delivered as a service.
The Drone Alert Service (DAS) gives organisations a simple, cost-effective way to detect and monitor unauthorised drone activity. Easy to deploy and already live across selected cities, DAS provides instant urban drone detection, real-time alerts, and a clear pathway to a scalable CUAS solution.
Accessible Airspace Awareness for Any Organisation
DAS was developed as OSL’s first drone detection as a service model, lowering the barrier for organisations that need airspace awareness but are not yet ready for a full CUAS deployment.
Instant Coverage
Available in areas supported by OSL’s urban drone detection network.
Drone Detection Without Hardware
Receive alerts directly with no need for on-site installation.
Actionable Intelligence
Real-time drone alerts with flight path and time-stamped logs.
Historical Data
Access past activity to understand patterns and support investigations.
Built to Scale as Threats Evolve
DAS is more than an entry-level CUAS. It is the first step in a layered strategy, enabling organisations to begin with lightweight drone defence and scale when required.
Layered expansion
Upgrade with radar, optical, and effector integration.
Flexible Delivery
Access DAS as a standalone service or part of a broader OSL solution.
Low False Positives
Proven accuracy in dense urban drone detection environments.
Future-ready Integration
Connect with OSL’s FACE® sensor fusion for scalable CUAS operations.
Drone Alert Service:
Intelligence, Accessibility, Flexibility
At airports, detection is only the start. Real protection means knowing when it’s safe to stand down, restoring confidence after every alert, and maintaining safe operations without overreaction.
Enhanced Situational Intelligence
The DAS Drone Alert Service delivers clear visibility of airspace risks. Real-time drone warnings and historical logs help organisations assess operational threats and plan investigations.
Designed for Ease of Use
Drone detection without hardware. No equipment to buy, no training or maintenance. Delivered entirely as a service, it gives instant awareness through an intuitive interface—ideal for lightweight drone defence.
Scalable on Demand
Adjust coverage or user access anytime. DAS can be managed independently or with OSL’s support team, ensuring a truly scalable CUAS solution.
