VPX3-673 CMOSS A-PNT & Radial Clock LRM, Aligned with the SOSA™ Technical Standard

3U VPX SBC with NXP LS1043A Arm Processor

For Assured Position, Navigation, and Timing (A-PNT)

The VPX3-673 is a specialized single board computer and timing card designed to eliminate the need for multiple in-platform boxes to field new navigational capabilities and simplify the integration of complementary PNT sources on ground vehicles.

• Aligned with the SOSA Technical Standard
• Enables Assured Position, Navigation, and Timing in Difficult Environments
• Provides Server for Radial Clock Distribution Applications
• Delivers High-Performance Capability in a 3U Footprint

Aligned with the U.S. Army’s C4ISR/EW Modular Open Suite of Standards (CMOSS) and OpenVPX Timing module standard, the SWaP-efficient VPX3-673 delivers state-of-the-art technology services, including a GPS/GNSS Receiver, Chip Scale Atomic Clock (CSAC), and an on-board Inertial Measurement Unit (IMU) – all within a single slot.

The VPX3-673 is also ideal for radial clock distribution applications and can provide a server for various low-power timing services. Serving as a low-skew clock master powered by a GPS-disciplined CSAC, the module offers a variety of configurable clock reference sources and support for up to 16 synchronized clock outputs.

Aligned with the SOSA Technical Standard

Choose from variants to support your specific requirements, including models developed in alignment with The Open Group Sensor Open Systems Architecture™ (SOSA) Technical Standard.

Enables Assured Position, Navigation, and Timing in Difficult Environments

The VPX3-673’s onboard 10 degree of freedom IMU makes it capable of precise motion tracking in a denied or untrusted GPS environment. Support for an onboard GB-GRAM type II GPS with SAASM or MCODE support is provided, including dedicated zeroize and keyfill functionality. An RS-232 port and RF 1 PPS input are provided for interfacing with an external RS-232 GPS sources.
