Septentrio PolaNt Choke Ring

*Built of aluminum, the ChokeRing full GNSS high precision antenna is designed for reference stations. It is recognized for its durability in harsh conditions and reliability. Featuring low-noise amplifiers, the ChokeRing full GNSS high precision antenna is enabled for multi-frequency reception (GPS, GLONASS, Galileo, BeiDou, NavIC, QZSS and SBAS) and to mitigate multipath by attenuating reflected GPS signals thus significantly improving the reliability and accuracy of your reading.



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

*Key features
