With open architecture systems gaining more and more traction in military and aerospace domains, the advantages of adopting open standards-based solutions are becoming ever more apparent. Today, systems integrators face mounting pressure to reduce size, weight, power, and cost (SWaP-C) for vehicle and aircraft electronics.

They must also meet tight delivery schedules and integrate commercial off-the-shelf (COTS) technologies that address unique technical requirements, while minimizing non-recurring engineering (NRE) costs. Typically, military and civil ground vehicle and aircraft platforms also have unique technical and platform I/O interface requirements that make finding a suitable COTS computing solution to meet 100% of their requirements very unlikely.

Leveraging Modular Open System Architecture for Modified COTS

This white paper describes how a modular open systems approach (MOSA) can be combined with modified COTS (MCOTS) solutions to meet unique system and program requirements and minimize NRE costs. By leveraging MOSA standards and MCOTS variants, systems integrators can reduce program risk and accelerate deployment of rugged embedded mission systems.
