Applying MOSA Approach to PXI-based ATS

초록

This paper discusses the approach to applying Modular Open Systems Approach (MOSA) to PCI eXtensions for Instrumentation (PXI)-based Automatic Test System (ATS). MOSA is a business and technical strategy for developing new systems or modernizing existing ones. It is widely applied in the defense sector and requires adherence to five principles. However, standards that follow MOSA, such as Sensor Open Systems Architecture (SOSA) and Hardware Open Systems Technologies (HOST), are designed based on VPX architecture, which presents limitations for applying these standards to PXI-based equipment. Consequently, while PXI-based equipment claims to adhere to MOSA, it is challenging to determine whether they comply with the five principles of MOSA. Similarly, Hanwha Systems has modularized the HW/SW architecture of its PXI-based ATS, but an analysis is needed to determine if it meets the five principles of MOSA. Therefore, this paper provides an analysis of Hanwha Systems' PXI-based ATS regarding its compliance with the five principles of MOSA and offers guidelines for ensuring MOSA compliance. Based on the overall analysis results, it is concluded that Hanwha Systems generally adheres to the five principles of MOSA. However, for Certification Conformance, there appears to be a need to develop a future Conformance Test Suite (CTS) specifically for MOSA-applied ATS in the field of certification testing. This paper analyzes Hanwha Systems' PXI-based ATS and, based on that analysis, presents a guide to meet the five principles of MOSA. This guide can be referred to not only by Hanwha Systems' PXI-based ATS but also by other PXI-based ATS to apply the five principles of MOSA. Consequently, this paper provides essential guidelines to help PXI-based ATS effectively implement the five principles of MOSA.
