ESCRIPTION
The DuraDBH-672 Digital Beachhead
™
is a rugged Commercial Off the Shelf (COTS) multi-function system
integrating a Gigabit Ethernet (GbE) switch and quad-core vetronics processor capable of supporting VICTORY
services and mounted Assured-Position Navigation Timing (A-PNT) capabilities in a MIL-STD-qualified small
form-factor chassis. The DuraDBH-672 builds on and extends many of Curtiss-Wright’s original DBH-670 Digital
Beachhead capabilities but in a lower Size, Weight, Power and Cost (SWaP-C) design capable of consolidating
network switch, vehicle processor, embedded GPS, atomic clock, inertial navigation, solid-state storage, and
add-in I/O interface all in a single Line Replaceable Unit (LRU). Featuring 16 ports of fully managed Layer 2
GbE switching/static Layer 3 routing together with a low-power, multi-core ARM-based i.MX6-Quad processor,
the DuraDBH-672 system supports not only general-purpose embedded computing/in-vehicle edge networking
requirements, but can also serve as a VICTORY Infrastructure Switch and Shared Processing Unit for the In-
Vehicle Network (IVN) Architecture adopted by the U.S. Army/US Marine Corps’ Vehicle Integration for
C4ISR/EW Interoperability (VICTORY) initiative. With optionally integrated Assured Position, Navigation and
Timing (A-PNT) components, including a military SASSM/M-Code GB-GRAM (Ground Based GPS Receiver
Application Module), a Chip Scale Atomic Clock (CSAC), and Inertial Measurement Unit (IMU), this highly-
capable system can enable cost-effective, accurate Mounted Assured-PNT (MAPS) functionality and affordable
PNT hub capabilities using non-GPS augmentation for mounted platforms.
Combining proven, high Technology Readiness Level (TRL) COTS subassemblies and open architecture
technologies into a single multi-function solution, this next-generation Digital Beachhead delivers a powerful
set of standard and optionally integrated capabilities. The unit’s carrier-grade network management software
provides a powerful feature set for multicast traffic, VLAN, port control, Quality of Service (QoS), Link
Aggregation, SNMP management, secure authentication, redundancy, precision timing (IEEE-1588 PTPv2), and
data zeroization. It’s multi-core processor provides a robust set of vetronics I/O interfaces (USB, GbE, RS-422,
RS-232, CANbus, DIO, HDMI) along with a modular I/O and storage architecture based Mini-PCIe cards and
mSATA SSD Flash storage modules to support application-specific I/O requirements (i.e. MIL-STD-1553 /
ARINC429 / COM / DIO modules). Application engineering services are available for modified COTS (MCOTS)
configurations at minimal/no NRE cost, including pre-integration of Mini-PCIe I/O cards. Tested to meet harsh
MIL-STD-810G and MIL-STD-461F requirements, the unit boasts fanless operation over a wide operating
temperature range (-40 to +71°C) and tolerance to extreme shock/vibration conditions, high altitude, and
humidity, making it suitable for technology refresh and new platform deployments, including mobile, tactical,
aerospace, and ground vehicle applications. It features front-panel MIL-DTL-38999 circular connectors in a
sealed IP67 (dust/ water proof) aluminum chassis together with industrial temperature grade components, EMI
filtering, and isolated MIL-STD-1275/704 power supply that protects against vehicle/aircraft voltage surges,
spikes and transients.
