DBH-672 Digital Beachhead Rugged Switch, Vehicle Processor and Assured PNT System
The DBH-672 Digital Beachhead is the first rugged Commercial Off the Shelf (COTS) single-box solution integrating a Gigabit Ethernet (GbE) switch and quad-core vetronics processor for supporting VICTORY services and mounted Assured-Position Navigation Timing (A-PNT) capabilities in a MIL-STD qualified, small form-factor chassis. The multifunction DBH-672 builds on Curtiss-Wright’s market leadership in VICTORY solutions, adding a lower size, weight, power and cost (SWaP-C) design to the Digital Beachhead family 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 and static Layer 3 routing together with a lowpower, multi-core Arm-based i.MX6-Quad processor, the DBH-672 system supports not only general-purpose embedded computing and 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 A-PNT components, including a military SAASM/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, Audio) 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. Qual-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 and 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 and water proof) aluminum chassis together with industrial temperature grade components, EMI filtering, and isolated MILSTD-1275/704 power supply that protects against vehicle and aircraft voltage surges, spikes and transients.
