Building a military-grade Unmanned Aerial System (UAS) requires technology that is not only high-performing but also extremely robust and fully hardened against severe environmental and electromagnetic challenges, meeting stringent specifications such as MIL-STD-810 and MIL-STD-461. The entire system is usually engineered across four critical and interconnected subsystems, from the drone’s computational ‘brain’ to the operator’s interface on the ground.
1. Flight Control and Navigation (The Avionics Brain)
The core function of any sophisticated drone is reliable, autonomous flight. For military applications, this necessitates processing units characterised by high performance and low-SWaP (Size, Weight, and Power).
These units must be capable of managing sensor fusion, executing real-time flight control algorithms, and performing complex navigation calculations, even when external aids like GPS are compromised or denied.
The primary processing solutions are derived from the Defence & Security product line. The primary Flight Management System is typically built around various rugged computing solutions such as Compact Mission Computers, Modular Mission Computers, and Airborne Military Computers, all designed to manage core avionics tasks. Furthermore, for demanding functions like real-time image recognition, sensor fusion, and onboard artificial intelligence, high-density computing is essential. This is delivered by robust solutions like GPU Servers and Rugged Blade Computers, which provide the necessary parallel processing capability in a hardened form factor.
Crucially, all internal avionics must be certified; Industrial Computers offer MIL-STD 461 Certified Computers for electromagnetic compliance and SFF & IP65 Modular Computers for protection against dust and water ingress.
2. Communications and Datalinks (The Backbone)
Secure, high-bandwidth, and low-latency communication is the vital link between the drone and the Ground Control Station (GCS), ensuring uninterrupted command and control (C2), and rapid transmission of high-resolution mission data. The industrial-grade networking hardware essential for managing this data flow is provided through specialised solutions. To manage the internal data network and prioritise C2 signals over voluminous sensor data, highly reliable Military Switches and Routers are necessary, which are specifically hardened against extreme temperatures and vibration.
Furthermore, systems must ensure clean, stable power to all avionics and communications gear; this is achieved using rugged Power Converters to regulate input voltage, and Media Converters to translate between different physical transmission standards, such as copper and fibre optic.
3. Flight Power, Control, and Airframe (The Platform)
While the airframe and propulsion systems are specialised aerospace components, the underlying control electronics required for their integration are critical. Custom flight control and interface boards often leverage industry-standard embedded formats for ease of development and upgrade. Industrial Computers offers modular computing in established formats such as VME, VPX, and CompactPCI boards, along with Single Board Computer Motherboards, which are commonly utilised in defence avionics. In addition, critical mission data, encompassing flight logs and high-definition video feeds, must be reliably recorded locally on fault-tolerant systems. The company addresses this need by supplying 2U Military Video Recorders & Systems specifically designed for reliable operation in rugged conditions.
4. Ground Control Station (GCS) Interface
The GCS serves as the main interface where human operators manage the drone, execute mission plans, and analyse the vast amounts of incoming sensor data. Since this interface is often deployed in mobile, ruggedised field shelters, the hardware must be extremely durable. Operators require highly reliable, clear displays; the company addresses this with rugged display solutions, including Military/Defence Panel PCs and High Brightness Rack Display Panels, which are designed to remain legible even in bright sunlight.
For smaller, tactical drone control or for quick-reaction teams operating away from the main shelter, portable command interfaces are essential. This demand is met by various Military/Defence Rugged Tablets and Ultra Rugged Tablets, allowing for mission execution and monitoring via a fully ruggedised, handheld platform.
