systems. Prior to its privatization, the company was involved in the development of three former German standard Information security projects. These include the IT Security Criteria (ITSK), the IT Evaluation Guide (ITEHB), and the IT Security Guide (ITSHB). The works appeared in 1989, 1990 and 1992. Among the successors of these works are the Common Criteria (published in 1996) and the IT basic protection manual published in 1994. Mobility, energy & environment In the Mobility business segment, the company carries out vehicle and traffic engineering, driving dynamics, driving comfort among others. The portfolio includes calculations on strength, dynamics and acoustics as well as structural tests on overall structures and components. Furthermore, the IABG examines the possibilities of transferring the magnetic levitation for individual traffic. In the energy business segment, solutions for electromobility and energy supplies are offered. The focus here is on the dismantling of nuclear power plants and the retrofitting of nuclear facilities as well as the qualification and engineering of wind power plants. In the environmental business area, the company focuses on geodata and environmental engineering. In its geodata factory in Dresden, IABG calculates and interprets spatial data, e.g. for surveying flooding areas, mobile radio planning or for municipal cadastres. Space travel The company carries out qualification tests on carrier rockets, such as the Ariane 5 upper stage and Vega, on satellites such as Swarm, LISA Pathfinder and Sentinel-2A, as well as other space structures in its space center coordinated by the ESA. These include mechanical, thermal and acoustic tests, the determination of mass properties as well as support services in engineering and quality management. Subsidiaries Acentiss Acentiss is subsidiary of IABG founded in 2008. They offer engineering services and develop the Elias aircraft (ELectric aircraft IABG AcentisS), a modified version of the PC-Aero Elektra One, presented in the ILA Berlin Air Show 2012 . Up to 2013, the aircraft is used in the bavarian research projects EUROPAS (2013-2016) and AURAIS (2017-2019). In Elias aircraft was designed a new structure of the wings and the landing gear, and it was developed the full electric reconnaissance system, datalinks, and ground control station. Acentiss collaborated in the construction of the rope-free elevator MULTI of ThyssenKrupp, winner of the German Design Award in 2018. Acentiss with the company HTM/Intercopter created a joint venture in 2018 called Advanced Aerospace Developments, which holds the EASA Part21J certification. One project is an external mirror
