VNX+: A Modular, Scalable Computing Architecture for Autonomous Vehicles

Uncrewed vehicles often experience severe space, weight, and power (SWaP) constraints when it comes to control and payload electronics. The VITA 90 (VNX+) and VITA 93 (QMC) standards give vehicle integrators a powerful tool to apply the Modular Open System Approach (MOSA) using commercial off-the-shelf components—minimizing deployment time and maximizing scalability.

Inside this white paper, you will learn:

• ✓ How the Sensor Open Systems Architecture (SOSA) Technical Standard incorporates VNX+ as a critical structural component.
• ✓ The role of high-bandwidth inter-node fabrics supporting configurations like PCIe Gen4 and 10/40GBASE-KX streaming data lanes.
• ✓ How the Unique External I/O (UEIO) segment provides direct I2C/SPI interfaces for small-system port expanders and actuators.
• ✓ The importance of QMC (VITA 93) small form factor mezzanines in expanding mission-dictated I/O capabilities without breaking SWaP budgets.
