WOBURN, Mass. – Concurrent Technologies Inc. in Woburn, Mass., is introducing the PR A11/61d-RCR rugged 3U VPX position, navigation, and timing (PNT) plug-in card for sensor-based uses in electronic warfare (EW) and intelligence, surveillance and reconnaissance (ISR) applications.
The card is designed in alignment with the Sensor Open Systems Architecture (SOSA) technical standard. The PR A11/61d-RCR is ITAR-free and is designed and built in the United Kingdom with technology licensed from Racelogic.
In normal operation, PR A11/61d-RCR sources PNT data from a built in GNSS receiver and uses this to discipline a chip-scale atomic clock (CSAC). This feeds radial clock signals to the signal-processing plug-in cards that make up a VPX based sensor subsystem.
In periods of GNSS denial or jamming, accurate PNT data continues to be provided by using signals from a built in inertial measurement unit and Kalman filtering techniques on the 3U VPX card.
The timing slot on most commercially available backplanes supports one or two 10GBASE-KR pipes and PR A11/61d-RCR is controlled using one or other of these pipes. Bused clock signals are also supported for backwards compatibility with older VPX systems.
