SPINAS. Customer: Airbus Defence & Space


SPINAS is a project to develop a modular electronic box concept based on the compact PCI serial standard with the target to design, build and implement electronic equipment for space applications faster, cheaper and more flexible while allowing increased use of COTS components.
A typical SPINAS derivate is in the 100W heat dissipation class.
Particular challenges are design for vibration, thermal and EMC performance for use on any satellite and inside the ISS.

EUCLID-Mission EUCLID-TT&R-Design


EUCLID - TT&R Subsystem. Customer: Antwerp Space


Euclid is an ESA mission to map the geometry of the dark Universe. The mission will investigate the distance-redshift relationship and the evolution of cosmic structures by measuring shapes and redshifts of galaxies and clusters of galaxies out to redshifts ~2, or equivalently to a look-back time of 10 billion years. In this way, Euclid will cover the entire period over which dark energy played a significant role in accelerating the expansion of the universe. The TT&R subsystem provides the Telecommand, Telemetry and Range functions.

PLATO-Mission PLATO-ICU-FEM


PLATO ICU. Customer: OHB Italia


PLAnetary Transits and Oscillations of stars (PLATO) is the third medium-class mission in ESA's Cosmic Vision programme. Its objective is to find and study a large number of extrasolar planetary systems, with emphasis on the properties of terrestrial planets in the habitable zone around solar-like stars. PLATO has also been designed to investigate seismic activity in stars, enabling the precise characterisation of the planet host star, including its age. The Instrument Control Unit (ICU) is part of the on-board Data Processing System and it is devoted to process and compress digital data inputs from 18 processing units. ICU will be also in charge of managing telemetry and telecommands to and from the Service Module (SVM) and to collect the payload's housekeeping and science data.
