DBH-670A combines a computer, Gigabit Ethernet switch, and A-PNT functionality into a rugged line replaceable unit (LRU) for military vehicles.

ASHBURN, Va. – The Curtiss-Wright Corp. Defense Solutions division in Ashburn, Va., is introducing the DBH-670A A-PNT Digital Beachhead A-PNT vehicle computer for assured-positioning, navigation and timing (A-PNT) applications in military ground vehicles. The VPX3-673 also is for radial clock distribution applications and can provide a server for various low-power timing services.

The new DBH-670A is a computer and Gigabit Ethernet switch that integrates A-PNT functionality from complementary PNT sources into a compact and rugged line replaceable unit (LRU) that also hosts a Vehicular Integration for C4ISR/EW Interoperability (VICTORY network switch and vehicle management computer.

The DBH-670A securely distributes A-PNT data across the vehicle in a trusted manner. Because it hosts the Defense Advanced GPS Receiver (DAGR) functionality within the VICTORY switch, the DBH-670A eliminates the need for a legacy DAGR LRU from the vehicle.

The DBH-670A integrates a multi-functional vehicle computer, Gigabit Ethernet switch, and a Arm computer in one rugged box. This Modular Open Systems Approach (MOSA)-based unit provides a chip scale atomic clock (CSAC) and an on-board 10-degree-of-freedom inertial measurement unit (IMU).

The DBH-670A also connects to an external GPS receiver, for real-time GPS position and time data. It can be configured optionally with an on-board GPS receiver that supports M-Code and SAASM.

Aligned with the U.S. Army’s C5ISR/EW Modular Open Suite of Standards (CMOSS) and OpenVPX timing module standard, the VPX3-673 module delivers technology services in one 3U VPX slot.
