Electric and Autonomous Flying

Urban mobility, that means all mobility items in urban areas from pedestrians to mass transit solutions, is changing dramatically. The future lies in new concepts like ride sharing, autonomous driving or air taxi.

Silver Atena is the system supplier for all electronic components in the field of Urban Air Mobility. The company have become very popular as a systems supplier to the aerospace industry for decades and is intensively involved with the new technical challenges of vertical take-off (light) electric aircraft. The current portfolio offers certifiable technical solutions in main areas of electric and autonomous flying to customers within the aviation industry: electric drives and actuators, power supply and distribution including battery management, avionic computing platforms for flight control and route planning or control units for innovative propulsion systems.
