Calian GNSS Ltd. is a leading developer and manufacturer of high-performance GNSS antenna solutions for UAVs (unmanned aerial vehicles) and robotics. UST is delighted to welcome Calian on board as a supplier partner, and we will be highlighting their unique solutions and capabilities across our channels over the next 12 months.
We’ve just launched Calian’s UST supplier profile, which has been written and built by our team in collaboration with the company. The Platinum profile showcases their cutting-edge antenna products, which are trusted by a range of unmanned systems and PNT (position, navigation and timing) industry leaders, including u-blox, Trimble, Septentrio and VectorNav.

Calian GNSS Smart Antennas combine cutting-edge antenna technology with integrated high-precision GNSS receivers, Inertial Measurement Units (IMUs), application processors and diverse digital interfaces to deliver flexible solutions that fit a broad swath of applications, from survey drones to smart agriculture to autonomous vehicles.
Cost-competitive single band antennas provide excellent solutions for telematics and timing, and include IMUs to assist in satellite obstructed “deep urban canyon” scenarios or even 100% satellite obstructed situations such as parkades. Dual-band high precision solutions incorporate advanced high-precision GNSS receivers from partners such as u-blox, delivering the cm-level precision required for autonomous driving applications.
Calian helical antennas are designed for SWaP (size, weight and power)-critical and high-performance applications such as UAVs. A precision-tuned helix antenna element delivers excellent gain and axial ratio over all elevation and azimuth angles, significantly minimizing multipath. Low-noise amplifiers (LNAs) with integrated low-loss pre-filters ensure high signal-to-noise ratios and excellent interference mitigation.
Featuring compact and lightweight construction and performing well without a ground plane, Calian’s helical antennas are ideal for UAV and unmanned systems precise point positioning (PPP) and real-time kinematic (RTK) applications.
VeroStar™ antennas are designed to receive all GNSS signals as well as L-band correction services, supporting demanding and advanced applications for aerial, ground and marine robotics and autonomous vehicles.
Featuring a unique design with crossed-driven dipoles that are fed in quadrature and coupled to wideband radiating elements, VeroStar™ technology is ideal for RTK and PPP applications, delivering excellent low-elevation tracking, low axial ratio, and stable phase center.
Calian’s single-band (L1/G1/E1/B1) Accutenna anti-jamming technology modifies the antenna radiation pattern so that jammer signals arriving from an elevation angle of +15 to -10 degrees above and below the horizon are blocked. In addition, antenna gain is slightly increased at high elevation angles.
The robust anti-jamming antennas can mitigate ground- or near ground-based jamming signals that can saturate the antenna’s Low Noise Amplifier (LNA) and prevent legitimate satellite signals from being passed to the GNSS receiver.
Calian eXtended Filtering (XF) technology is designed to provide the cleanest possible GNSS and L-band corrections signals, mitigating interference from sources such as LTE and 5G, Iridium, Globalstar, and Inmarsat.
eXtended Filter GNSS antennas feature high-linearity front-end amplifiers with additional pre-filters for each frequency band right at the antenna element feed, integrated with the diplexer for dual/triple-band antennas and with additional in-line filters.
