Crisa (Computadoras, Redes e Ingeniería , S.A.U.) is a Spanish company founded in 1985 to design and manufacture electronic equipment and software for space applications: satellites, launchers, orbital infrastructure and space transportation vehicles. Other activities include engineering projects for ground stations.

Crisa is fully integrated into Airbus Defence and Space, Europe’s number one defence and space enterprise.

Crisa has played a relevant role in most ESA's scientific and Earth observation missions, developing payload processors and hardware and software controllers: data processing units, control units, power conditioning and distribution units, ground segment and test bench equipment.

All of these developments play a vital role in monitoring the Earth's for surveillance, managing infrastructure, observing natural events, as well as the scientific research of the Universe. Some of the main missions that carry this equipment on-board include Meteosat Second Generation, Envisat, MetOp, Rosetta, Mars and Venus Express, Herschel, Planck, GOCE, ATV vehicles, NASA’s Mars rover Curiosity, Gaia or Ariane 5 and Vega launchers. Presently, more than 50 projects are being undertaken for future upcoming missions like Ingenio, Paz, LISA Pathfinder, Sentinel, BepiColombo, EathCARE, Solar Orbiter or Meteosat Third Generation among others.

Crisa is also very active in telecommunication satellites developing various electronic units for communications satellite platforms like Eurostar E3000, AlphaBus and SmallGEO.
