Curtiss-Wright Marks Historic Release of SOSA™ Technical Standard Release 1.0 with Open Standards Guide

ASHBURN, Va. – October 6, 2021 – Curtiss-Wright’s Defense Solutions, a leading supplier of rugged modular open systems approach (MOSA) solutions engineered to succeed, today congratulated The Open Group and the Sensor Open Systems Architecture™ (SOSA) Consortium on the public release of SOSA Technical Standard 1.0.  The standard, developed through the collaboration and participation of government and industry working together, defines open system reference architectures applicable to military and commercial sensor systems. Curtiss-Wright is an active contributor to the definition and advancement of the SOSA standard and is a key participant in several SOSA Consortium working groups (including holding a chair position in the SOSA Consortium). By establishing guidelines for C5ISR systems, the new standard fosters flexibility in the selection and acquisition of sensors and subsystems that provide sensor data collection, processing, exploitation, communication, and related functions over the full life cycle of the deployed system.

Curtiss-Wright has also recently published a new guide, “Modular Open Systems Approach (MOSA): Why Open Standards Like CMOSS and SOSA are the New Normal,” that provides an overview of these important open standards and how they impact new embedded system requirements. The guide can be downloaded here.
“The release of the new SOSA Technical Standard is a milestone event for the embedded aerospace and defense industry,” said Chris Wiltsey, Senior Vice President and General Manager, Curtiss-Wright Defense Solutions division. “The SOSA Technical Standard  will help drive interoperability and reduce the costs associated with rapidly fielding today’s most advanced radar processing, communications, electronic warfare (EW), electro-optical/infra-red (EO/IR) and signal intelligence (SIGINT) applications, as well multi-INT sensor systems, to the warfighter. As a proud contributor and participant in the development of this important standard, we extend our congratulations to The Open Group and the SOSA Consortium on this historic achievement.”

Based on modular design and widely supported, consensus-based, nonproprietary standards, the SOSA Technical Standard defines key interfaces to meet the following goals:
  • Reduce development cycle time and cost
  • Reduce systems integration cost and risk
  • Increase commonality and reuse
  • Reduce sustainment and modernization cost
  • Support capability evolution and mitigate obsolescence
  • Enable technology transition
  • Facilitate interoperability
  • Isolate the effects of change

Why long-term consistent performance matters for relative humidity sensors

Sponsored by Texas Instruments

The open cavity sensing element included in relative humidity sensors is constantly exposed to the environment, leading to drift over time. The new relative humidity sensor, the HDC3020, offers integrated drift correction technology to reduce drift caused by environmental stress or interactions with contaminants. This article discusses the accuracy and long-term drift of humidity sensors and how these parameters impact end-equipment performance and lifetimes.
