Septentrio PolaRx5TR GNSS Timing Receiver

The Septentrio PolaRx5TR GNSS timing receiver is a robust, multi-frequency GNSS time and frequency transfer receiver, optimized for quality of code and carrier phase measurements. It is fully compliant with recommendation CCTF 5 (2015) of the Consultative Committee for Time and Frequency and is IP65 certified.



Dedicated to time and frequency transfer applications, the PolaRx5TR GNSS timing receiver from Septentrio is optimized for quality of code and carrier phase measurements. This receiver is fully compliant with recommendation CCTF 5 (2015) of the Consultative Committee for Time and Frequency.

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).

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.

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.
