PolaRx5 is a versatile and robust multi-frequency GNSS reference receiver. The unique design of its tracking provides measurements with the lowest noise on the market while constantly monitoring and protecting against ionospheric interference, multipath and other environmental effects. 

The PolaRx5 is developed specifically to support the most demanding applications for the earth science community offering a select range of advanced features which enable maximum accuracy and functionality. Powered by Septentrio’s next generation multi-frequency engine, the PolaRx5 offers 544 hardware channels for robust and high quality GNSS tracking. Septentrio’s field-proven Advanced Interference Mitigation (AIM+) technology enables the PolaRx5 to filter out both intentional and unintentional sources of radio interference, from narrowband signals over high powered pulsed signals to chirp jammers and Iridium interferers.

Septentrio’s patented APME+ multipath mitigation technology – unique in eliminating short delay multipath without introduction of bias – guarantees superior measurement quality. If needed, the user has the ability to activate or deactivate APME+ to obtain completely unmodified measurements.

Furthermore, various independent tests have shown PolaRx5 consistently ranks highest among GNSS receivers in many areas of measurement quality, including fewest number of cycle slips and lowest power consumption well below 2W.
