Multi-frequency, multi-constellation Ionospheric Monitoring GNSS Reference Receiver

  • Real time output of TEC & scintillation indices output
  • 100Hz code, phase and intensity output with user controlled noise bandwidth
  • 100Hz unfiltered correction output
  • Signal tracking across the full GNSS spectrum 
  • Unique Advanced Interference monitoring and mitigation (AIM+) + advanced GNSS+ toolkit
  • Durable housing and multiple communications options 

Consuming less power than many of its competitors, the PolaRx5S generates ultra-low noise scintillation indices and GNSS measurements while logging and streaming data at up to 100 Hz. The PolaRx5S compact and durable housing, low power consumption and open technology make it ideal for rapid and efficient integration into your existing network.

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
