Precise, Reliable, Flexible
Satellite control with Engineering Base
Airbus Defence and Space GmbH, formerly EADS Astrium, is the aerospace sector of the Airbus Group. It specializes in cosmonautics and space-based services. In Europe, the company employs about 11,000 staff members. A focus of the Ottobrunn division is among other things on satellite ground station antennae and large measuring systems for satellite antennae e.g. for telecommunication, earth observation, science and navigation. More than 15 test systems have already been installed worldwide. The measuring halls contain two huge reflectors weighing several tons with meticulously milled precision surfaces. To be able to measure the radiation over different solid angles, the antenna superstructures of the satellites are precisely aligned with the reflectors using a multi-axle positioning system.
For the electrical design of the highly complex drive technology and the sensory system as well as for the ground station antennae for satellite monitoring and control, Airbus Defence and Space has been relying for several years on Engineering Base (EB) from AUCOTEC. The object-oriented and database-driven E-CAE tool contains everything the aerospace specialists need.
The functional gaps of the software products tested before EB made it clear which functions were indispensable for the needs of the satellite experts: e.g. the function-oriented copying simply by drag & drop. The ease of learning and the intuitive handling, supported by familiar Microsoft tools such as Visio for the graphics, SQL server and VBA, were decisive criteria. With EB, distinctly more transparency and above all consistency of the design and documentation data is ensured.
From Spitsbergen to South Africa
An important business segment of the former Astrium is the maintenance of the ground station antennae. Regular upgrades demand absolute precision in the documentation and optimum preparations because these stations usually are located in remote places of the globe, e.g. Spitsbergen or South Africa. Even with the best of preparations, unexpected changes may be required locally. In this case it is essential to act quickly and flexibly. For this purpose EB is ideal, for even with simultaneous worldwide online access from the notebooks of several users one always gets an up-to-date status of the ongoing work. In this context the Airbus Defence and Space engineers confirmed that the system was easily understood and made engineering much easier.
