nxFCU Dual

Redundant Flight Control Unit

The nxFCU Dual is an extension of the baseline nxFCU, offering a tightly integrated dual redundant navigation, flight control and mission management solution for UAVs. Ideal for high-end Tactical and Mini UAVs, this rugged, single failure tolerant unit, with dissimilar hardware and safety certifiable software, provides the ultimate in automation reliability in a SWaP sensitive design. Communication reliability is ensured through redundant LOS and BLOS data links, while video streaming is enhanced to include in-flight compression, archiving and retrieval for a complete avionics solution.
