Since 1986 TechSAT GmbH has been a reliable and competent partner of the aerospace industry, supporting aircraft systems development, integration, test, and maintenance with state-of-the-art equipment and services. TechSAT’s core competence is the design and development of test systems for integration, verification, and validation of aircraft systems including related consulting and services. Core is ADS2, a modular and scalable integrated software/hardware platform, which forms the basis for a wide range of real-time integration-, and production acceptance test systems. From a single component up to a highly integrated test facility, which is capable of testing individual aircraft systems and also complete functions by clustering individual test benches into larger clusters. Additionally we provide a wide range of software applications, such as data loaders, protocol simulations, and analyzers, as well as signal I/O products specifically optimized for aerospace applications. TechSAT was a major supplier for most large aerospace programs of the last two decades, among others Airbus A340, A380, A350, A400M, Boeing 777, 787, EFA, and Tiger.
