The Septentrio PolaRx5TR. Septentrio has launched its most advanced GNSS receiver for dedicated time and frequency transfer applications, the PolaRx5TR. The PolaRx5TR is the newest addition to Septentrio’s PolaRx product line of GNSS receivers, which led to the selection of Septentrio as preferred vendor for reference stations to UNAVCO for 2015-2018. The PolaRx5TR has 544 hardware channels and supports all major satellite constellations including GPS, GLONASS, Galileo, BeiDou, QZSS and IRNSS. A calibration circuit is incorporated into the PolaRx5TR to measure and compensate for the internal delay. This feature removes the need for calibration using external equipment and ensures measurement latching is always accurately synchronized with the PPS input. Septentrio’s newest receiver is compliant with the new-format CGGTTS version V2E of Consultative Committee for Time and Frequency (CCTF) recommendations. Also included as standard is Septentrio’s Advanced Interference Mitigation (AIM+) technology, giving outstanding interference robustness in difficult radio environments. Furthermore, up to eight independent logging sessions can be configured logging to either the 16-GB internal memory or to an externally connected device. “Septentrio’s timing receivers have established themselves as trusted market leaders for time and frequency transfer applications,” said Francesca Clemente, product manager for the PolaRx product line. “The PolaRx5TR continues in this tradition with updated GNSS technology, compliance to new standards set by CCTF and an auto-calibration feature reducing initial setup times.”
