OSCAR, the ‘brain’

Versatile and powerful on-board computer

OSCAR is a versatile and powerful on-board computer, based on innovative technology. It is a high-performance, low-cost product available for Earth observation, navigation, science and telecoms applications.

OSCAR is the latest in the line of on-board computers developed by Airbus Defence and Space

This photo of the OSCAR on-board computer was taken on the Airbus Defence and Space site in Elancourt (Paris), during final testing before integration on the host satellite.

OSCAR is the latest in the line of on-board computers developed by Airbus Defence and Space. The on-board computer is part of the avionics subsystem and the ‘brain’ of the satellite platform. It manages the vital on-board functions, such as attitude and orbit control, execution of remote-controls received from the ground, management and transmission to the ground of telemetry from the equipment, synchronisation generation and distribution, and fault detection.

OSCAR is already operational on the new-generation observation satellite SPOT 6, launched in September 2012, and is also baselined for other European applications such as SPOT 7, the Spanish SEOSAT satellite, the Kazakhstan export programme and ESA’s Sentinel 5 Precursor.

OSCAR benefits from the very latest innovations and is the first use of the SCOC3 ‘System-on-a-chip’ developed by Airbus Defence and Space. This component, the equivalent of a computer’s microprocessor, uses the very latest electronic technologies, enabling it to integrate all the functions of the on-board computer on just a single component. This offers highly significant savings in computer weight, volume and power consumption. OSCAR only weights 4.9 kg and consumes only 15 W, while offering unprecedented computing power when compared with the previous generation. The resources offered by OSCAR allow the implementation of increasingly sophisticated control algorithms and satellite management strategies.
