Recab – Robust 3U VPX position, Navigation & Timing kort

Engelsk: The PR A11/61d-RCR is a rugged 3U VPX Plug in Card (PIC) for high accuracy & resilient Position, Navigation & Timing (PNT). It is design in alignment with SOSA ™ Technical Standard to be suitable for Electronic Warfare & Cyber Security applications. Areas of use – military land, sea & air applications.

Rugged 3U VPX Plug in Card (PIC)
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.

Feature:
⇒Integrated multi-constellation, multi-frequency GNSS module with interference and jamming mitigation
⇒ Chip Scale Atomic Clock (CSAC) and Inertial Measurement Unit (IMU) for assured Position Navigation and Timing
⇒ Differential radial clock distribution
⇒ Coaxial Antenna and Timing signals in P2 aperture

Supported for backwards compatibility with older VPX systems.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 utilizing 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.
