AUSA 2021, Walter E. Washington Convention Center, Washington D.C. (Curtiss-Wright Booth 1051/Curtiss-Wright PacStar Booth 7849) – October 11, 2021 – Curtiss-Wright’s Defense Solutions division, a leading supplier of modular open systems approach (MOSA) based solutions, introduced two new natural convection-cooled system solutions designed in compliance with the U.S. Army CCDC C5ISR Center’s CMOSS standard and aligned with the SOSA™ Technical Standard 1.0 at the AUSA 2021 Annual Meeting and Exposition (October 11-13, 2021).

In support of its commitment to lead the industry in delivering rugged MOSA solutions, Curtiss-Wright announced the new CMOSS/SOSA Starter Kit (CSSK). Designed for use on ground combat vehicle (GCV) platforms, the CSSK speeds the development and demonstration of CMOSS/SOSA solutions by providing a pre-integrated 4-slot SWaP-optimized 3U VPX system that combines a VICTORY network module (Aligned with SOSA Profile: 14.4.14 DP/CP Switch), A-PNT module (Aligned with SOSA Profile: 14.9.2 Radial Clock), single board computer (aligned with SOSA Profile: 14.2.16 I/O Intensive) and 3U VPX power supply unit.

Curtiss-Wright also announced its new 8-Slot CMOSS/SOSA aligned Enclosure that provides a highly configurable rugged platform for Ground Mobile and GCV environments. The powered chassis features 8 3U OpenVPX slots, all of which are aligned with the SOSA Technical Standard 1.0. It features one External I/O slot, one I/O Intensive Compute Slot, four Generic Payload slots, one Data Plane/Control Plane Switch Slot, and one Radial Clock Slot that supports Assured-PNT functionality.

Curtiss-Wright’s new CMOSS chassis are designed to meet the U.S. Army PEO Ground Combat Systems (GCS) Standardized A-Kit / Vehicle Envelope (SAVE), a new standard that defines internal mounting and physical interfaces for connecting CMOSS systems and radios to platforms. These fan-free chassis are ideal for use in Ground Combat Vehicle, and Tactical Wheeled Vehicle Platforms, as well as high-performance ground or rotary-wing processing applications.

“Curtiss-Wright is leveraging its industry-leading MOSA hardware and system integration expertise to bring the widest range of CMOSS and the SOSA Technical Standard 1.0 aligned solutions to market,” said Chris Wiltsey, Senior Vice President and General Manager, Curtiss-Wright Defense Solutions. “In support of the DoD’s mandate for MOSA-based solutions, our new CMOSS/SOSA Starter Kit and 8-Slot CMOSS/SOSA aligned rugged chassis help ground vehicle system designers rapidly get started on demonstrating and fielding their new applications and delivering new capabilities to the warfighter.”

About the CSSK:

The CMOSS/SOSA Starter Kit packages best-in-class system building blocks in a ready-to-run 28V powered 3U OpenVPX chassis. This compact enclosure is pre-integrated with:

  • VPX3-687: VICTORY Network
    • Integrated Ethernet switch module provides 1GbE VICTORY network capabilities to the platform.
  • VPX3-673: A-PNT
    • Integrated A-PNT card has integrated CSAC, IMU, and GBGRAM Type-II SAASM/M-Code receiver. External network-enabled sensors can also be added and integrated with the pntOS software.
  • VPX3-1260: Intel 8th Gen Xeon Processor
    • Integrated Intel 8th Gen Xeon E-2276ME SBC provides general-purpose processing for hosting battle management software (JBC-P/MMC), in addition to other applications, in a virtualized environment.
About the 8-Slot CMOSS/SOSA Technical Standard 1.0 aligned 3U OpenVPX Chassis:

The new 8-Slot CMOSS/SOSA aligned powered enclosure provides the highest functional density available using natural convection cooling. It accommodates a wide range of capability and I/O, with little-to-no modification, enabling this enclosure to be part of the A-kit, or fixed infrastructure, hardware for all Army ground vehicles. All of the 8-Slot Chassis’ slots are aligned to the SOSA Technical Standard 1.0. They support one External I/O slot, one I/O Intensive Compute Slot, four Generic Payload slots, one Data Plane/Control Plane Switch Slot, and one Radial Clock Slot providing Assured-PNT functionality. It also provides Dual Power Supplies and supports load sharing. Software support includes Curtiss-Wright’s Embedded Chassis Manager.

A Leader in Open Standards

Curtiss-Wright is an active contributor to the definition and advancement of the open standards included in CMOSS and those being defined in The Open Group Sensor Open Systems Architecture (SOSA). Curtiss-Wright has been a leading participant in the development of the CMOSS and SOSA standards since the inception of both initiatives and is a key participant in several SOSA Consortium working groups (including holding a chair position in the SOSA Consortium). In addition, the company has been a leading contributor to the VITA Standards Organization (VSO) that oversees the definition of the OpenVPX, PMC, XMC, and FMC form factor standards that provide the foundation of both CMOSS and SOSA Technical Standards. This makes Curtiss-Wright ideally positioned to work with customers to help guide the development and success of their CMOSS and SOSA aligned applications.
