Bohemia, NY – September 2024 – North Atlantic Industries (NAI), a leading provider of rugged embedded solutions for military and aerospace applications, is excited to announce the launch of its latest Sensor Interface Units (SIUs): the SIU32S, SIU34S, and SIU36S. These rugged system chassis are designed to accommodate various SOSA™-aligned profile plug-in cards (PICs), delivering unmatched versatility, scalability, and performance to meet the demands of modern military and aerospace environments.

Building on NAI’s Configurable Open Systems Architecture™ (COSA®) and aligning with the Modular Open Systems Approach (MOSA), the SIU32S, SIU34S, and SIU36S support a wide range of mission-critical applications, including mission computing, vehicle management systems, actuator interface units, data acquisition, fire control and targeting systems, remote data concentrators, health and usage monitoring systems, and aircraft interface units.

The SIU32S features two 3U SOSA™ OpenVPX™ card slots, supporting up to six video, I/O, and communication smart function modules, making it ideal for space-constrained applications requiring high-density I/O and processing capabilities. The SIU34S offers four slots for up to twelve smart function modules, providing enhanced capacity for more complex systems. The SIU36S boasts six slots and can accommodate up to eighteen modules, offering maximum flexibility for the most demanding environments.

All three chassis support multiple SBCs and processor options, including Freescale PowerPC™ QorIQ® T2080, Intel® Core™ i7 or Xeon® W (Tiger Lake), and ARM® Cortex®-A53 or -A72, ensuring compatibility with a variety of processing requirements. They also feature HD38999 I/O connectors, dual 28 VDC power inputs, and support for operating systems, including Wind River® Linux, VxWorks®, and Ubuntu Linux®.

"The introduction of the SIU32S, SIU34S, and SIU36S represents a significant advancement in our ability to provide rugged, configurable solutions that meet the evolving needs of military and aerospace applications," said Lino Massafra, VP of Sales & Marketing at NAI. "These new SIUs leverage our COSA® technology to deliver unparalleled performance, flexibility, and reliability in the harshest environments."

The SIU3xS family also supports connectivity options, such as 4x HD-BNC for 3G SDI video input/output and fiber optic connections for high-speed Ethernet, including Time-Sensitive Networking (TSN), ensuring these units are equipped to handle advanced application interfaces. They are designed to meet stringent environmental, EMI/EMC, and input power standards, including MIL-STD-810, MIL-STD-461, MIL-STD-1275, and MIL-STD-704, ensuring reliable performance in challenging conditions.

Beyond their core functionalities, these SIUs are engineered to support adjunct mission processing for advanced applications such as high-density I/O, communications, Ethernet switching, Assured Positioning Navigation and Timing (A-PNT), video capture, graphics processing, machine learning, and artificial intelligence. This makes them ideal for accelerating the deployment of Size, Weight, and Power (SWaP)-optimized systems across air, land, and sea platforms. Additionally, these SIUs allow for scalable configurations that can adapt as requirements evolve without requiring software changes. The flexibility extends to cooling options, with both conduction-cooled and air/convection-cooled chassis available.

NAI’s new SIUs are now available to support the next generation of military and aerospace systems. For more information, visit the NAI website or contact our sales team.
