Nano Flight Control Unit

The nxFCU is the Nano variant of S-PLANE’s renowned xFCU, a state-of-the-art navigation, flight control and mission management unit for fixed and rotary wing UAVs. The nxFCU was specifically optimised for Size, Weight and Power (SWaP), without compromising ruggedness, reliability or certifiability of the solution. The result is a highly functional yet physically compact design able to meet the strict unmanned aviation regulations of the future.

The nxFCU is ideally suited to Tactical and Mini UAVs for both civil and military applications. Integrated navigation sensors, a wide range of highly configurable I/O and embedded LOS and BLOS communication links, provide it with the flexibility and capability of meeting almost any automation requirement. Reliability is ensured through a rugged hardware design, a safety certifiable software architecture and optionally distributed redundancy, making the nxFCU the responsible choice for UAV system integrators.

The nxFCU is also available in dual redundant (nxFCU Dual) and compact (nxFCU Compact) configurations. Contact S-PLANE for further information and support in selecting and configuring an nxFCU for your system.
