The DBH-670A is a highly integrated, multi-functional vehicle computer and Ethernet switch that combines assured positioning, navigation, and timing (A-PNT) functionality, a powerful Gigabit Ethernet switch, and a power-efficient Arm computer in a single box. Designed to provide ground vehicles with access to trusted PNT information while operating in conditions with limited, impeded, or denied GPS/GNSS, it’s rapidly deployable and size, weight, and power (SWaP)-optimized for space-constrained platforms.
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 onboard 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 a 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 onboard 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.
