Septentrio PolaRx5 GNSS Reference Receiver

The Septentrio PolaRx5 GNSS reference receiver is a high-precision, multi-frequency receiver with low noise measurements, unique interference monitoring and an IP65 certification.



The PolaRx5 is a versatile and robust multifrequency GNSS reference receiver. It provides measurements with the lowest noise and cycle slip rate on the market while continuously monitoring and protecting against interference, multipath and other environmental effects.

The PolaRx5 tracks all visible signals generating ultra low noise measurements. It produced the lowest number of cycle slips to offer the highest number of observations per slip during independent competitive testing.

AIM+ can suppress the widest variety of interferers, from simple continuous narrowband signals to the most complex wideband and pulsed jammers. APME+ multipath estimator, unique in its ability to tackle short-delay multipath, enhances measurement quality while LOCK+ guarantees robust tracking of rapid signal dynamics during scintillation events or earthquakes.

Automatic transfer of data from a receiver to a remote server can result in lost data or the unnecessary retransmission of complete data files. Specifically developed to minimize network usage for telemetry, the PolaRx5 features SYNC+, a fast differencing algorithm that analyses data files at the remote location and transfers only the missing parts.

Communication and (remote) management of the PolaRx5 is made easy with a powerful built-in Web UI which features secured access to all receiver settings and status information, data storage and fast firmware upgrading. SBF, RINEX, BINEX, MSM and NMEA data logging is possible on both the internal 16 GB memory and to an externally connected device. Up to 40 data jobs can be defined and logged data can be accessed via the Web UI or automatically pushed to a FTP server.
