The Modular Open Systems Approach (MOSA) is a DoD strategy for building systems from modular, interchangeable parts connected by open interfaces, so capabilities can be upgraded and sourced competitively over a platform’s life. The Sensor Open Systems Architecture (SOSA) applies that idea to sensor and C4ISR processing, defining a technical standard that builds on OpenVPX (VITA 65) so boards from different vendors work together. NewTec Reps represents suppliers of SOSA-aligned hardware for defense and aerospace programs.

MOSA vs. SOSA in plain terms

MOSA is the policy and approach. SOSA is one concrete technical architecture that delivers it for sensor systems.

Where VPX fits

SOSA-aligned systems are built on 3U OpenVPX. The pieces you typically need:

• SOSA/MOSA-aligned VPX backplanes
• VPX enclosures and chassis
• VPX power supplies (VITA 62)
• Small form factor SOSA systems
• Rugged mission computers

Frequently asked questions

Is SOSA the same as OpenVPX?

No. SOSA builds on OpenVPX and adds further requirements for interoperability.

Does “SOSA-aligned” mean certified?

Not necessarily. Ask the manufacturer what alignment means for a given part.

Can NewTec help me choose?

Yes. NewTec Reps matches program requirements to supplier products. Tell us about your program.
