Assured Position, Navigation and Timing solution for defence applications

Concurrent Technologies announce a rugged 3U VPX™ Position, Navigation and Timing (PNT) Plug In Card.  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. 

Dr Miles Adcock, CEO at Concurrent Technologies, commented: “The development of this new PNT plug  in card shows that Concurrent Technologies is now investing in products that provide additional  differentiated capability alongside our state-of-the-art single board computers. This product will have  universal appeal but was driven by the needs of several lead customers who are looking to Concurrent  Technologies to bolster the scope of UK sovereign capability for assured PNT.”  

Julian Thomas, Managing Director at Racelogic, added: “We have designed and manufactured high  precision, resilient position and timing solutions for use in automotive, mining, construction and laboratory  environments for over 20 years. In this case we have provided Concurrent Technologies with a solution  that enables their 3U VPX Plug In Card to provide PNT information during long periods of GNSS denial to  fit the needs of the defence community.”

Want early design analysis without simulation?

Sponsored by Siemens Digital Industries Software

Traditional verification methods are failing today's complex IC designs, which require a proactive, early-stage analysis approach. A shift-left methodology addresses IP block integration challenges and the limitations of traditional simulation and ERC tools. Insight Analyzer detects hard-to-find leakage issues across power domains, enabling early analysis without full simulation. Identify inefficiencies earlier to reduce rework, improve reliability, and enhance power performance.
