DSI Aerospace GmbH is a SME located in Bremen, Germany, providing high-end electronics for airborne and space applications. Founded as a spin-off of the University of Applied Sciences Bremen in 1997 by Professors Dr H. Michalik and Dr L. Hinsenkamp, DSI has continued to deliver future-oriented solutions since that time in terms of both aerospace technology and IT security systems. The fields of activity are dedicated to the engineering, development, manufacturing and qualification of solutions for aerospace electronic equipment, information technology and advanced communication systems. We are specialised in designing digital systems, which provide significant savings in required resources in terms of power consumption, mass and volume. At the same time, our integrated approach provides significant increases in processing power as well as in reliability due to the usage of the newest, qualified FPGAs and ASICs technologies.
