VNX+ Modular Computing Architecture for Autonomous Vehicles

This white paper presents the VNX+ (VITA 90) modular computing architecture designed for autonomous vehicles, focusing on its application in space-constrained environments. It outlines the challenges faced by uncrewed vehicles regarding space, weight, and power (SWaP) constraints, and how the VNX+ and QMC (VITA 93) standards address these issues by enabling the Modular Open System Approach (MOSA). The paper details how the Sensor Open Systems Architecture (SOSA) incorporates VNX+ as a critical element, facilitating the integration of commercially available components for efficient system design. It discusses the advantages of using VNX+ and QMC, including reduced costs and improved deployment times compared to custom designs. The document also highlights the technical specifications of VNX+, including its form factors, connector configurations, and utility segments, which support interoperability and replaceability in system integration. Additionally, it examines the implications of these standards on system design decisions, including thermal considerations and the benefits of leveraging COTS components.
