Saab has a long and successful tradition of building fighter aircraft renowned for their state-of-the-art cockpit design. This legacy is transferred to the UAS Control Station through the understanding of what it takes to develop airborne systems that let operators focus on their mission objectives, keeping them in control rather then just at the controls.

Seeing is believing


The UAV Control Station (UCS) is built as a scalable system that enables operators to focus on the mission with a clear and simple way of controlling both air vehicle and payload.

A single operator is required to control the Skeldar vehicle and its payload, but the operator roles (air vehicle & payload) can be distributed by users of the system to suit their organisational (personnel) structure.

Simple commands by the principle of ‘Point-and-See’ and ‘Point-and-Fly’ as well as intuitive functions and tools contribute to the ease of operation during all phases of a mission. Consequently the training of operators can focus more on tactical issues rather than technical ones.

Reliability and Compatibility Combined

The UCS is compatible with the NATO STANAG 4586, which specifies the division of a UAV Control Station into a Vehicle Specific Module (VSM) and a non-specific vehicle module called Core UCS (CUCS).

This division implies that the UCS should be configurable to control different types of unmanned vehicles through the implementation of a VSM, and to have a transparent handling of payload and mission data between the VSM and CUCS through a specified interface called DLI (Data Link Interface).

The Skeldar UCS takes this division even further by having a system design that guarantees the integrity of the information and commands sent to and from the UCS.

A Flight Safety Critical (FSC) Computer containing the VSM, implemented to Design Assurance Level DO-178B, DAL C (or higher if specified), controls all flight-critical information and controls which information and commands are sent to and from the UCS.

To ensure flight safety of the UAS, the Flight Safety Critical Computer is redundant. The CUCS software is installed onto a Mission Computer, connected to the FSC Computer, and is responsible for handling the mission and payload control, i.e. all non-flight-critical information and controls.  

Due to the separated design of flight-critical and non-flight-critical information and control, the CUCS only requires Design Assurance Level DO-178B, DAL D. The Mission Computer could be a stand-alone computer or part of an existing computer network, e.g. a C4I-system.    

Given this relationship between the FSC and Mission Computer, the system design is not only compliant with the NATO STANAG 4586, it also ensures the integrity of the information and commands, while being adaptable to different configurations (installations), types of air vehicle and payloads.


The interaction with the UCS is tailored to allow the operator to focus on the mission objectives. The display layout of the UCS utilises the separation of Flight Safety Critical and Mission Data to give the operator a straightforward means of controlling and monitoring the AV and its payload. 

Flight information is presented on a touch-sensitive display called Flight Display and is connected to the FSC computer, which contains all information and High Level Commands needed to control and monitor the AV in all phases of the flight.

Thanks to the high level of autonomy, each basic task such as start up, takeoff, hold, landing and shut-down, is carried out by pressing a single button. Given the design and reliability of the FSC Computer, key information and control are guaranteed to be continually available to the operator.
