The PolaRx5e is an IP68 compliant GNSS reference receiver complete with battery. It offers GNSS performance identical to that of the PolaRx5

PolaRx5e 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 multipath and other environmental effects. 

Powered by Septentrio’s next generation multi-frequency engine, the PolaRx5e offers 544 hardware channels for robust and high quality GNSS tracking. Septentrio’s field-proven Advanced Interference Mitigation (AIM+) technology enables the PolaRx5e 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.

The PolaRx5e 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. 

Independent tests have shown the PolaRx5e to consistently rank highest among GNSS receivers in many areas of measurement quality, including fewest number of cycle slips and lowest power consumption below 2W.

The GNSS+ toolkit - converting bad environments into good positioning

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 Multipath Mitigation (APME+) 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.

Mechanical vibrations or shocks caused by rough terrain can wreak havoc with satellite tracking. LOCK+ automatically adjusts the parameters of your receiver so you never lose position.

AIM+ anti-jamming and RF spectrum monitoring system

AIM+ offers built-in protection against intentional and unintentional jamming using a sophisticated system of sampling and mitigation mechanisms. Your high-precision GNSS / GPS receiver can automatically suppress the widest variety of interferers from simple continuous narrow-band signals to the more complex wide band and pulsed transmitters as well as lnmarsat and Iridium satellite transmissions. 

Intuitive Web User Interface


Web interface of the Septentrio PolaRx5(e) reference receiver


With your high-precision GPS reference receiver comes an intuitive web user interface for easy operation and monitoring allowing you to control the receiver from any mobile device or computer. The web interface also uses easy-to-read quality indicators ideal to monitor the receiver operation during the job at hand.
