Septentrio offers multi-constellation CORS for DOTs

A new PolaRx5 Continuously Operating Reference Station (CORS) platform, offered by Septentrio Americas, is optimized for state departments of transportation (DOTs) and other real-time-kinematic (RTK) network operators.

The PolaRx5 CORS receivers can be purchased at special pricing by UNAVCO member organizations and affiliates. Septentrio has been selected by UNAVCO as the preferred vendor of CORS receivers under a multi-year agreement.

The PolaRx5 is powered by Septentrio’s AsteRx4 next-generation multi-frequency engine. It offers 544 hardware channels and supports all major satellite signals including GPS, GLONASS, Galileo and BeiDou, as well as regional satellite systems such as QZSS and IRNSS.

Septentrio’s 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 transmitters.

In addition, Septentrio’s patented APME+ multipath mitigation technology guarantees superior measurement quality by eliminating short-delay multipath errors without introduction of bias, the company said.

The PolaRx5 leverages Septentrio’s web interface and built-in Wi-Fi and Bluetooth interfaces to give users complete control and visibility of the receiver. The user interface integrates into existing network management systems. The web browser provides secure access to all receiver settings and status, data storage and firmware upgrades, as well as a built-in spectrum analyzer for system monitoring.

“The multi-constellation PolaRx5, with its powerful interference and multipath mitigation and new Web interface, is the ideal solution for DOTs to modernize their aging CORS installations to the newest GNSS technology,” said Neil Vancans, vice president of Septentrio Americas.
