NX-FCU CSC

Dual Redundant Control and Sensors

The NX-FCU CSC is a baseline NX-FCU, 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. The NX-FCU 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 strict aviation safety regulations.

The NX-FCU CSC is ideally suited to Tactical and Mini UAVs for both civil and military applications. Available with a selection of state-of-the-art internal navigation sensors and with a wide range of highly configurable I/O, the NX-FCU CSC provides an unparalleled level of flexibility and capability to meet almost any automation requirement. Reliability is ensured through a rugged hardware design (DO-254) and a safety certifiable software architecture (via DO-178C) combined with sensor and computational redundancy, making the NX-FCU CSC the responsible choice for UAV system integrators.

The NX-FCU CSC is also available with integrated dual redundant communication links (NX-FCU CSMC) and various custom build options (incl. CM, CS and VSM). Contact S-PLANE for further information and support in selecting and configuring an NX-FCU for your system. Units are supplied as complete FCUs or as FCU hardware with Board Support Packages (for PikeOS and real-time Linux).
