Septentrio PolaRx5 GNSS Reference Receiver

The Septentrio PolaRx5 GNSS reference receiver is a high-precision, multi-frequency receiver with low noise measurements, unique interference monitoring and an IP65 certification.



The PolaRx5 GNSS reference receiver from Septentrio offers a unique tracking design that results in measurements with the lowest noise and cycle slip rate on the market. This occurs while continuously monitoring and protecting against interference, multipath and other environmental effects.

PolaRx5 combines various technologies to offer the highest quality 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 or earthquakes. AIM+, advanced interference mitigation, enables the PolaRx5 to filter our radio interference, from narrowband signals over high powered pulsed signals to chirp jammers and Iridium interferers.

The PolaRx5 GNSS reference receiver is ideal for networking, remote operation and data logging. Its built-in Web UI provides secure access to all settings, status information, data storage and fast firmware upgrading, making PolaRx5 easy to manage.

SBF, RINEX and BINEX data logging is possible on both the built-in 16 GB memory and on an externally connected device. Up to 24 data records can be defined: 8 independent sessions with 3 data formats per session. Logged data can be accessed via the Web UI or automatically pushed to a FTP server. It comes with RxTools which is a suite of applications that complements the Web UI with advanced monitoring, conversion and analysis tools. Use any device with a web browser to monitor and configure the PolaRx5 via the built-in webserver accessible over WiFi, network or USB connection.
