The Curtiss-Wright CSSK speeds development of CMOSS and SOSA components by providing a pre-integrated four-slot 3U VPX embedded computing system.

ASHBURN, Va. – The Curtiss-Wright Corp. Defense Solutions segment in Ashburn, Va., is introducing two convection-cooled embedded computing systems that comply with the U.S. Army CMOSS standard and align with the SOSA Technical Standard 1.0.

Curtiss-Wright announced the CMOSS/SOSA Starter Kit (CSSK) for use on ground combat vehicles. CMOSS stands for Command, Control, Communications, Computers, Cyber, Intelligence, Surveillance, Reconnaissance (C5ISR)/Electronic Warfare Modular Open Suite of Standards, while SOSA stands for Sensor Open Systems Architecture.

The CSSK speeds development of CMOSS and SOSA components by providing a pre-integrated four-slot 3U VPX system. It combines a SOSA-aligned network module that complies with Vehicle Integration for C4ISR/EW Interoperability (VICTORY) standard; a SOSA-aligned assured position, navigation, and timing (A-PNT) module; a SOSA-aligned single-board computer; and a 3U VPX power supply.

Curtiss-Wright also announced a rugged eight-slot CMOSS-compliant and SOSA-aligned enclosure for military combat vehicles. The powered chassis has eight 3U OpenVPX slots, one External I/O slot, one I/O-intensive compute slot, four generic payload slots, one data plane/control plane switch slot, and one A-PNT radial clock slot.

Curtiss-Wright's CMOSS chassis meet the U.S. Army PEO Ground Combat Systems Standardized A-Kit / Vehicle Envelope (SAVE) -- a standard that defines internal mounting and physical interfaces for connecting CMOSS systems and radios to platforms. These fan-free chassis are for combat vehicles and helicopters.
