Accutenna® 4 (AC4) Series from Calian
GNSS has shifted to a multi-constellation, multi-frequency landscape, and legacy antenna designs can no longer keep pace. Modern Real-Time Kinematic (RTK) and Precise Point Positioning (PPP) applications demand advanced accuracy, reliability, and consistent performance. That’s where Calian’s Accutenna® technology sets a new standard for lightweight, full-band GNSS antenna solutions.
Accutenna leverages a proprietary dual-feed ceramic patch architecture that delivers a true circular response across ~80 MHz of bandwidth while powerfully rejecting cross-polarized multipath interference. Building on this foundation, Calian’s Accutenna® 4 (AC4) Series introduces a rugged, full-band quad-feed design for even greater precision and signal integrity.
Accutenna® (AC4) Key Features:
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: Advanced four-feed compact stacked composite patch antenna minimizes multipath interference and keeps the phase center stable, ensuring centimeter-level accuracy.
Lightweight, Rugged Options: Available as embedded (85g) and in multiple mounting styles to suit 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.
Accutenna® (AC4) Key Applications:
The AC4 Series is purpose-built for precision applications:
Surveying
Autonomous Systems
Precision Agriculture
GNSS performance expectation will continue to rise as precision systems become more interconnected, autonomous, and bandwidth-intensive. The AC4 Series delivers the accuracy, stability, and interference resilience required for future-proof precision applications.
