VPX3-673A CMOSS A-PNT & Radial Clock LRM

The VPX3-673A from Curtiss Wright is a rugged 3U OpenVPXâ„¢ A-PNT module designed to ingest positioning data from multiple sensors and output consistent timing and navigation information to the warfighter

Overview

The VPX3-673A is a rugged 3U OpenVPXâ„¢ 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.

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.

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.

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.
