Calian GNSS launches advanced antennas for high-precision operations

Calian GNSS, a leader in high-precision antenna technology, has introduced the Accutenna 4 (AC4) antenna family for increased accuracy, reliability and performance across the full GNSS spectrum.

Based on a novel stacked composite patch antenna element, the AC4 element combines a robust and compact, full band quad-feed design, in half the weight of current patch antennas on the market. Its highly efficient radiating element and precise phase pattern associated with Calian’s proven eXtended Filtering (XF) technology will deliver clean and accurate signals, even in today’s crowded RF environment.

Whether it’s surveying, autonomous systems, precision agriculture or defense, the AC4 ensures users can rely on GNSS data when it matters most.

Designed with precision applications in mind:

• Full GNSS band coverage. Supports GPS, Galileo, BeiDou, GLONASS, SBAS and correction services in one antenna, making it a versatile, future-proof solution.
• Accutenna 4 technology. Four-feed compact stacked composite patch antenna minimizes multipath interference and keeps the phase centre stable, ensuring centimetre-level accuracy.
• Lightweight, rugged options. Available as embedded (85 g) and in multiple mounting styles for diverse applications, from embedded systems to demanding field use.
• Noise rejection. Integrated Extended Filtering (XF) technology blocks interference from new LTE and other signals that can disrupt GNSS performance.

With the Accutenna 4, Calian GNSS expands its portfolio, reinforcing its role as a partner for organizations that depend on precision GNSS antenna innovation.
