Smart Antenna HX-COX012A

Overview

HX-COX012A is a multi-band multi-constellation embedded smart antenna developed by Harxon. Combining Harxon’s world leading antenna technology with Unicore’s full-constellation full-frequency RTK positioning module. HX-COX012A delivers precise positioning performance in a compact and integration-ready structure. It’s able to provide single point meter level accuracy, DGPS sub-meter level accuracy and RTK centimeter/millimeter level accuracy, very suited for various UAV applications that require precise location and precise heading.

Key Features

Integrated Design and Compact Form Factor

The compact smart antenna, weighing only 12g and measuring Φ46*H19.2mm, greatly reduces the weight of UAVs and features low power consumption.

Precision-Tuned GNSS Helical Antenna

The main part of HX-COX012A is an ultra-low profile Harxon helix antenna designed for high precision positioning of UAV. It excels in offering superior satellite signal tracking.

High Performance RTK Positioning Module

Integrated with Unicore’s full-constellation full-frequency RTK positioning module, which integrates RF, baseband and high precision algorithm, it can track multiple frequencies of all GNSS systems, enabling high-precision RTK positioning.

Strong Anti-Interference Performance

HX-COX012A equips a robust pre-filtered LNA that features an excellent out-of-band interference rejection performance, and the module features 60 dB narrowband anti-jamming and advanced jamming detection technology
