DBH-670A A-PNT Vehicle Computer and Switch

Multi-Functional Full System Solution

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

Designed to provide ground vehicles with access to trusted PNT information while operating in conditions with limited, impeded, or denied GPS/GNSS, the DBH-670A is rapidly deployable and size, weight, and power (SWaP)-optimized for space-constrained platforms.

• Enables A-PNT in Challenging Environments
• Delivers High-Performance Switching
• Built with a Modular Open Systems Approach

DBH-670A uniquely integrates a multi-functional vehicle computer, a powerful Gigabit Ethernet (GbE) switch, and a power-efficient Arm computer in a single box.

Enhance trust and safety with the DBH-670A:

Enables A-PNT in Challenging Environments

The DBH-670A provides a GPS-disciplined Chip Scale Atomic Clock (CSAC), that serves as an excellent high-performance, low-skew clock master. Its on-board 10 degree of freedom inertial measurement unit (IMU) delivers precise motion tracking in limited, impeded, or denied GPS/GNSS environments. The DBH-670A also supports direct connection to an external GPS receiver (NMEA, DAGR, or equivalent) for real-time GPS position and time data. It can be optionally configured with an on-board GPS Receiver (upgradeable to M-Code).

Delivers High-Performance Switching

Built around a non-blocking core fabric, the DBH-670A’s 16-port Ethernet switch provides tri-speed operation (10/100/1000 Mbps) with auto-negotiation and auto MDIX. Its feature-rich networking includes support for IPv4/v6, VLANs, IGMP multicast, QoS, MSTP/RSTP, link aggregation, port mirroring, and jumbo frames. The network switch also includes full support for hardware-based Precision Time Protocol (IEEE-1588v2), enabling the network nodes to synchronize with nanoseconds of accuracy.

Built with a Modular Open Systems Approach

Curtiss-Wright designs rugged modules and systems like the DBH-670A in alignment with MOSA open standards to shorten our customers’ development times, simplify technology upgrades and interoperability, and reduce solution costs.
