Septentrio PolaRx5S Ionospheric Monitoring GNSS Receiver

The Septentrio PolaRx5S ionospheric monitoring GNSS receiver offers a durable housing, low power consumption and open technology, making it ideal for rapid and efficient integration into the existing network.



The PolaRx5S ionospheric monitoring GNSS receiver from Septentrio offers 544 channels that provide I&Q correlations, phase, code and carrier-to-noise at up to 100 Hz for all GNSS L-band frequencies. It features an ultra-low noise oscillator enabling precise phase scintillation monitoring with a phase noise standard deviation as low as 0.03 rad.

PolaRx5S combines various technologies to offer the best possible quality of measurements for position calculations. The APME+ is unique in its ability to tackle short delay multipath and enhances measurement quality while LOCK+ guarantees robust tracking of rapid signal dynamics during scintillation events. PolaRx5S also incorporates advanced interference mitigation techniques to suppress interference before it can affect the iono indices.

The PolaRx5S is ideal for networking, remote operation and data logging. Its built-in Web UI offers secure access to settings, status information and data storage while allowing for fast firmware upgrades. This Web UI is accessible over WIFI network or USB connection. SBF, RINEX and BINEX data logging is possible on the built-in 16 GB memory and on any externally connected device. Up to 24 independent data archives can be defined. Logged data can be accessed via the Web UI server or automatically pushed to a FTP server. It comes with RxTools which is a suite of applications that offers advanced monitoring, conversion and analysis tools.
