Smart Choke Ring Antenna for GNSS Base Station Applications

Calian VCX6000XF

The VCS6000XF Smart Choke Ring from Calian is the industry’s first full-scale precision Smart Choke Ring antenna that synergizes a full-spectrum GNSS antenna with an embedded “All-in-View” receiver for high-accuracy base station deployments. Delivering simultaneous tracking of all visible satellite constellations and signal bands, the VCS6000XF enables seamless remote management through IP-based connectivity.

With complete GNSS capabilities and L-Band support from Septentrio, the VCS6000XF provides key advanced interference and signal integrity technologies, including:

• AIM+: Industry-leading interference suppression that counters a broad spectrum of jamming and spoofing threats—from narrowband continuous signals to complex pulsed and wideband disruptors.

• IONO+: Sophisticated ionospheric scintillation mitigation to maintain signal integrity during geomagnetic disturbances.

• APME+: A unique post-processing multipath estimator that effectively reduces both code and carrier phase multipath, especially short-delay reflections, enhancing measurement precision.

• LOCK+: Exceptional signal tracking resilience under intense mechanical stress, such as vibrations or seismic activity, ensuring consistent performance during dynamic conditions.

• RAIM+: Built-in autonomous integrity monitoring to ensure reliable and trustworthy positioning data.
