PR A11/61d-RCx conduction cooled 3U VPX Position, Navigation and Timing Board

3U conduction cooled VPX plug-in card for high accuracy and resilient position, navigation and timing applications with a 4-core 1.8 GHz ARM v8 A72 processor with secure boot and up to 8 GB soldered DDR4 ECC SDRAM for management and configuration. The board has an integrated GNSS receiver module for common SAT systems, high accuracy time synchronization (Chip Scale Atomic Clock) and a built-in inertial measurement unit.

The Concurrent Technologies PR A11/61d-RCx offers two 10GBase-KR ports with IEEE802.1AS Precise Time Protocol (PTP), which enables synchronization of systems to within 100ns of each other and Network Time Protocol (NTP) to enable synchronization to within 1ms or better. In addition, a maintenance port with Command Line Interface (CLI) is available for easy user configuration on P1.

The board is aligned with the SOSA (Sensor Open Systems Architecture) technical standard to be suitable for future electronic warfare and cyber security applications. The SOSA (Sensor Open Systems Architecture) consortium is a voluntary, consensus-based membership consortium of the Open Group, a vendor-neutral technology standards organization that develops an open technical standard for sensors.
