DBH-670A A-PNT Vehicle Computer and Switch
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.

What is Assured Positioning, Navigation and Timing?
The potential vulnerabilities of the military’s dependence on Global Positioning System (GPS) and Global Navigation Satellite System (GNSS) data are driving demand for new deployed approaches for detecting threats. In GPS/GNSS-denied environments, ensuring accurate Positioning, Navigation and Timing (PNT) information is delivered to the warfighter is absolutely critical.
