In October 2022, Curtiss-Wright Corporation’s Defense Solutions division, a supplier of modular open system approach-based solutions, released the VPX3-673A module. This module is the first to deliver assured position, navigation and timing (A-PNT) along with alternative RF navigation and pntOS architecture.
The VPX3-673A is a rugged, 3U OpenVPX, form factor module, which integrates with existing navigation sensors in vehicles operating in environments with limited or denied access to GPS, to increase assurance in the platform’s PNT solutions. It is designed to ingest positioning and timing data from multiple sensors and output accurate timing and navigation information on the battlefield using VICTORY data messages.
It is compatible with the United States Army’s C5ISR/EW Modular Open Suite of Standards and aligned with the Sensor Open Systems Architecture Technical Standard 1.0.
VPX3-673A includes a low noise chip-scale atomic clock with intelligence provided by Xilinx MPSoc, an alternative RF navigation receiver and a 10-degree of freedom IMU. It supports an internal or external GPS module via a front panel connector. Additionally, the VPX3-673A provides processing resources and sensor interface capabilities needed for operability with a variety of external processing and sensor units.
