Details

Designed in alignment with the SOSA ™ Technical Standard, PR A11/61d-RCR provides resilient PNT data for sensor based solutions that are used in Electronic Warfare and Intelligence, Surveillance and Reconnaissance applications.  As a key differentiator, PR A11/61d-RCR is ITAR free and is designed and built in the UK utilising technology licensed from Racelogic, another UK company specialising in positioning data.

In normal operation, PR A11/61d-RCR sources highly accurate PNT data from a built in GNSS receiver and uses this to discipline a Chip Scale Atomic Clock (CSAC).  This, in turn, 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 utilising signals from a built in Inertial Measurement Unit and sophisticated Kalman filtering techniques.  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.  Bussed clock signals are also supported for backwards compatibility with older VPX systems.
