SOSA™ Aligned Technology

In order to achieve interoperability of different systems and components in the field of embedded computing, the SOSA™ standard was developed. A consortium of various companies led by the U.S. Department of Defense has developed SOSA™ (Sensor Open Systems Architecture) as a COTS-based open standard that provides reconfigurable, rapidly upgradable, and cost-effective embedded computing capabilities.

Based on OpenVPX, this new standard provides a comprehensive architecture that enables component integration and interoperability with a modular approach to embedded systems development.

HARTMANN Electronic and W-IE-NE-R Power Electronics are jointly developing high-performance components based on the SOSA™ standard, such as a backplane, chassis manager and more.

High-speed performance and great flexibility characterize the SOSA™ Aligned backplane from Hartmann Electronic. As a central connection element, the backplane is crucial for the performance of the overall system. That’s why Hartmann has equipped its SOSA™ Aligned backplane, which is optimized for compute-intensive applications, with plenty of power. It is designed as a high-speed backplane with 100 Gigabit Ethernet.

The backplane’s high-speed performance of 100 Gbit/s has also been proven in independent tests.

The seven slots of the backplane offer the possibilities to integrate a wide range of functionalities. Based on customer information, their long experience and analyses, the specialists at Hartmann Electronic have decided on a specific configuration. However, this can also be modified and adapted to customer-specific requirements at any time.

High Degree of Flexibility


The SOSA™ Aligned Development Chassis was developed according to aesthetic and functional criteria. The open design allows optimal access to the respective backplane. The outstanding feature of the chassis is the cooling. Up to ten high-performance fans are integrated and ensure sufficient cooling for every conceivable board application. In addition, the chassis is characterized by its flexible usability and an extremely powerful power supply.

The development chassis is optimized for Hartmann’s 7-slot SOSA™ Aligned backplane, but all other backplanes can also be used. With the chassis, Hartmann primarily addresses two target groups: manufacturers of VPX boards who want to test their boards in the system, and system integrators who configure systems from several boards.

State of the Art Power Technology


The VPX340 and VPX336 series are commercial off-the-shelf (COTS) conduction-cooled, ruggedized, small-form-factor power supplies according to the VITA 62.0 specification.

The VPX340 (400W) and VPX336 (360W) can be used to power VPX / Open VPX chassis and will fit into the standard envelope defined by VITA 48.0 specifications.

They are designed for military and aerospace applications and MIL-STD compliance tested according to MIL-STD-461F, MIL-STD-704F and MIL-STD-1275D.

High overall efficiency is achieved using state-of-the-art switching power technology. The VPX power supplies are outfitted with advanced features, such as reverse-input polarity protection, EMI filtering, full over / under voltage and surge protection, over current and over temperature protection, and operate within a wide input range voltage.

VITA 46.11 Chassis Manager

Operating as software on the SOSA™ Aligned Development Chassis, the Chassis Manager complies with VITA 46.11. It is responsible for implementing functions to manage the entire SOSA™ sensor system. These functions include state detection, configuration, control, monitoring and logging, fault handling, testing, diagnostics, and safety management.

The Chassis Manager performs these functions both when the system is operating (in-band) and when it is offline or malfunctioning (out-of-band). The Chassis Manager communicates with all components in the chassis and with higher-level units in the operating environment. It collects information about the operating status, temperature, and the type, number, and condition of the installed cards.


Thanks to advanced manufacturing using 3D printing, Hartmann’s new Lightweight ATRs are up to 45 percent lighter than previous Air Transport Racks – a critical factor in aerospace applications. This manufacturing method also improves heat dissipation and EMI performance significantly. Additive manufacturing makes it possible to produce a fully customized enclosure.

The Air Transportation Rack (ATR) is the de-facto standard form factor for aircraft board electronic equipment since more than 50 years. The two ARINC drawings SK-141-10 and the SK-141-17 with detailed critical dimensions and tolerances for the initial 3 basic form factors, via the ½, 1 and 1 ½ ATR became the basis for ARINC 404A as it is used even today.

Hartmann 100GBase VPX Technology

HARTMANN Electronics continues to push the boundaries of speed. New routing methods designed for stable frequency transmission of up to 12.5 GHz enable 100-Gbit Ethernet on SOSA™ Aligned backplanes.

The backplane has also demonstrated this high-speed performance in an independent test at the Harting Corporate Technology Services laboratory, which is certified to DIN EN ISO/IEC 17025: 2005.
