VPX3-673A 3U CMOSS/SOSA Aligned A-PNT Module with Integrated Software

The VPX3-673A is a rugged 3U OpenVPX™ A-PNT module designed to ingest positioning data from multiple sensors and output consistent timing and navigation information to the warfighter. At the heart of the VPX3-673A is a low noise Chip Scale Atomic Clock (LN-CSAC), with intelligence provided by an AMD MPSoC. These devices are complemented by an Alternative RF Navigation receiver and a 10-degree of freedom Inertial Measurement Unit (IMU).  The board supports an internal GPS module capable of both SASSM and M-CODE, or an external GPS via an easily accessible front panel connector.

Open Standards Approach
The VPX3-673A was developed in alignment with the SOSA technical standard, and delivers connectivity for up to 11 clocks. An additional feature being developed only for the VPX3-673A is the ability to link two or more of the Radial Clock A-PNT modules, which delivers 22 plus precision clock outputs. In addition to the open hardware standards, the VPX3-673A distributes PNT information via standard VICTORY data messages in compliance with the CMOSS Mounted Form Factor (CMFF) architecture. 

Faster Development: Alternative RF Navigation and pntOS Optimized Together
The VPX3-673A offers two powerful, new A-PNT features: Alternative RF Navigation and pntOS. 
Designed to operate without GPS, Alternative RF Navigation (alternative navigation) provides position and timing information using a space-based commercial system. By providing Alternative RF Navigation directly on the SBC, system integrators no longer have to develop it themselves.

A government-funded open architecture, pntOS is a software framework enabling system integrators to quickly develop assurance algorithms and add plugins for new sensors. By leveraging pntOS, the time and effort to develop cutting-edge assurance algorithms is greatly reduced. 

Unique in the industry, the VPX3-673A provides both Alternative RF Navigation and pntOS already optimized to work together. Pairing these two features with the VPX3-673A provides the tools for developers to react quickly and mitigate emerging threats. 

Ecosystem Flexibility for Greater Assurance
System requirements vary greatly depending on platform type. The VPX3-673A provides both the processing resources and sensor interface capabilities to be compatible with a wide variety of external processing and sensor units. Having the ability to use many different types of sensors, including radio navigation (GPS, Alternative RF Navigation), environmental sensors (Barometer, Compass, LIDAR, Inertial) and platform-specific (pitot tube, odometer) sensors allows for the highest assurance PNT.
