What is CMOSS?

CMOSS is a suite of standards that support the reduction of the size, weight, and power of C5ISR and EW systems while increasing their flexibility and adaptability by enabling the sharing of hardware and software components.

These standards have been defined to help integrators move the implementation of C5ISR capabilities away from the use of costly and complex separate “boxes” on individual platforms.


CMOSS is being included in and managed under the Sensor Open Systems Architecture (SOSA) initiative with U.S. Military participation.

CMOSS = The C5ISR/EW Modular Open Suite of Standards


C5ISR = Command, Control, Communications, Computers, Cyber, Intelligence, Surveillance, and Reconnaissance

EW = Electronic Warfare


Orolia Defense & Security is a proud member of the Sensor Open Systems Architecture™ (SOSA) Consortium.



At the core, C5ISR/EW systems use many of the same technologies, but they are not always compatible between systems. CMOSS seeks to create a common architecture that these technologies can integrate into, providing many benefits.

Reduces integration costs and risks

Mitigates Obsolescence

Facilitates interoperability and reuse

Accelerates fielding and deliveries


How is CMOSS Being Implemented?

•  Universal A-Kit – Project Managers field capabilities as cards into a common chassis


•  Pooled radio resources such as antennas and amplifiers for Communications, 

    Electronic Warfare (EW), and Signals Intelligence (SIGINT) system


•  Shared processing resources such as computers and displays


•  Shared data services such as Position, Navigation, and Time (PNT)


•  Foundation for enhanced interoperability and simultaneity between C5ISR systems


•  Reduced life cycle cost through increased competition, smaller logistics tails with

    common sparing, and upgrading to the latest hardware as parts are replaced


•  Rapid insertion of new technology/capability


CMOSS Architecture

Software Layer

•  Enables portability of software applications across hardware platforms

•  Software framework selected based on mission area

Functional Decomposition

•  Allows for sharing of RF resources such as antennas and amplifiers

•  Defines interfaces between RF functions and components

•  Enables best of breed along with rapid component upgrades

Hardware Layer

•  Enables capabilities to be fielded as cards in a common chassis

•  Common form factor including physical, electrical, and environmental specs

Network Layer

•  Provides connectivity within platform, defines interfaces between capabilities

•  Enables legacy systems to share services within the converged architecture
