The VPX Timing Card offers a complete solution set for all PNT needs. This ruggedised conduction-cooled unit provides versatile, multifunction, highly-stable clock references for any environment.
The VPX Timing Card provides three (3) 1000BASE-KX Ethernet ports, with optional software upgrade for faster 10GBASE-KR. The Ethernet ports support PTP (IEEE 1588-2008) and NTP functionality (RFC 5905) with both server and client capabilities.
The P1 backplane provides 11 individually programmable AUX (1PPS) and REF (10MHz-3GHz) radial clocks, with standard output at LVDS levels. Non-standard LVPECL output levels are available for lower jitter requirements. These radial clocks have a maximum group skew of ±25 picosecond between pairs, while the PPS inputs to outputs phase alignment is maintained within ±10ns. Furthermore, each clock phase can be further tuned within ±25 picoseconds to calibrate module radial clock routing.
The P2 backplane is fitted with a 14-port VITA 67.3C aperture (10-port optional), providing standard inputs for 1PPS and 10MHz synchronization sources. It optionally supports commercial GNSS, secure M-Code GPS, analog PPS and sine outputs, as well as timecode inputs and outputs.
Developed timecode I/O modules include: HQ1, HQ2, ICD-GPS-060 (PTTI HQ), IRIG-AM, IRIG-DCLS, NMEA 0183, STANAG 4372 (Saturn i & ii), STANAG 4430 (XHQ) and MIL-STD-1553.
The VPX Timing card can be optionally configured with a CSAC for enhanced holdover accuracy while operating in reference-denied environments. As an added feature the raw GNSS data can be distributed via multicast from the module for downstream processing.
To facilitate higher level integration, selected 3rd party source code is available to build status and control applications software on platforms running almost any operating system. e.g. Single Board Computer (SBC). Applications connect using gRPC over HTTP via Ethernet or even locally using RS-232 console access via localhost.
Additionally, the unit can be outfitted with a triaxial MEMS-based IMU with multi-layered Kalman filtering for increased position and navigation accuracy.
