Septentrio PolaRx5

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 interference, multipath and other environmental effects.


Data Sheet

Precise and solid heading calculation

544 channels for tracking all known and future signals from GPS, GLONASS, GALILEO, BEIDOU, NavIC, QZSS & SBAS on both antennas

Centimetre-level (RTK) and dm-level (PPP) position accuracy

Septentrio GNSS+ algorithms for solid performance even in regions of evaluated ionospheric activity

Multiple Connections Options

Integrated cellular modem, Bluetooth and WiFi; optional UHF radio

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.

Key features

    • Tracks all visible GNSS signals (GPS, GLONASS, Galileo, BeiDou, IRNSS)
    • High precision, low noise measurements
    • Unique interference monitoring
    • Powerful web interface and logging tools
    • Rugged housing and multiple interfaces
    • Up to 8 independent logging sessions
    • Logging both internally and to an external device
    • Internal battery for autonomous >24-hour operation (only available on PolaRx5e)
    • IP68 compliant (only available on PolaRx5e)

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

Independent tests have shown the PolaRx5 to consistently rank highest among GNSS receivers in many areas of measurement quality, including the fewest number of cycle slips and lowest power consumption well below 2W.

The IP68 compliant variant, the PolaRx5e is also available which comes complete with battery. The GNSS specifications of the PolaRx5 and PolaRx5e are identical. The physical specifications differ slightly and are documented in the PolaRx5 datasheet.
