Calian’s full-band GNSS antennas deliver precision-tuned, full-constellation performance for high-accuracy positioning across autonomous land, marine, and aerial platforms. Each model employs a twin circular, quad-feed stacked patch with a wideband LNA design to achieve low axial ratio, tight phase-center stability (≤2 mm from zenith to 15°), and consistent RTK/PPP accuracy across all GNSS constellations and L-band correction services.
Engineered with Calian’s XF filtering, the antennas provide exceptional rejection of adjacent-band interference from LTE, Ligado, and Inmarsat transmissions. A range of rugged housings and mounting options from embedded OEM platforms to survey-grade threaded bases support reliable integration in demanding environments. Connector configurations include TNC, N-Type, and MCX options for flexible system compatibility.
