PolaRx5TR

 DOWNLOAD

Dedicated to time and frequency transfer  applications, the PolaRx5TR is optimised for quality  of code and carrier phase measurements. The  PolaRx5TR is fully compliant with recommendation  CCTF 5 (2015) of the Consultative Committee for Time  and Frequency.

KEY FEATURES

„Ultra-precise time synchronisation for timetransfer applications

„PPS IN internal delay auto-calibration

„CGGTTS V2E compliant

„Tracks all visible signals (GPS, GLONASS,GALILEO, BEIDOU, NAVIC)

„

OSNMA Support

„

High-precision, low-noise measurements

„

Unique interference monitoring and mitigation

„

Powerful Web UI and logging tools

BENEFITS

Timing As well as the standard inputs for time and frequency, the  PolaRx5TR incorporates a calibration circuit to measure  and compensate for the delay between the PPS input and  the internal time reference. This ensures the measurement  latching is always accurately synchronised with the PPS input.  Additionally, PPS out signal allows for long-term monitoring  of internal delay stability. CGGTTS data for the GPS, GLONASS, Galileo and BeiDou  constellations is generated with RxTools both on the receiver  board and on PC and can be automatically transferred  over FTP. The CGGTTS files are fully compliant with V2E, in  accordance with recommendation CCTF 4 (2015). GNSS technology PolaRx5TR is built around the GReCo4™ multi-constellation  tracking processor, and provides 544 hardware channels  which are assigned automatically and on-the-fly to all visible  satellites. Advanced interference analysis and mitigation  using adaptive filtering facilitates operation in difficult radio  environments, including near chirp jammers. Networking, remote operation and data logging Communication and (remote) management of PolaRx5TR  is made easy with a powerful built-in Web UI accessible  over WiFi, network or USB connection. The Web UI features  secured access to all receiver settings and status information,  data storage, and fast and robust firmware upgrading. SBF,  RINEX and BINEX data logging is possible on both a built-in  16 GB memory and on an externally connected device.
