Introduction

Harxon HX-CUX014A (L1+L2) is a compact, low-profile embedded active GNSS antenna for UAVs, small robots and autonomous vehicles, supporting GPS, GLONASS, Galileo and BeiDou. Advanced multipoint feeding technology delivers stable phase center performance, while up to 4 dBi antenna gain and wide-angle circular polarization support reliable low-elevation satellite tracking. A pre-filtered LNA suppresses out-of-band interference for consistent GNSS reception. Measuring 64 × 64 × 13.4 mm and weighing ≤90 g, its low power consumption and compact structure simplify integration into space-constrained platforms for navigation and precise positioning.

Strong Interference Rejection with Pre-Filtered LNA

Key Features

Consistent Performance Across GNSS Frequency Bands

The antenna supports GPS, GLONASS, Galileo and BeiDou for reliable multi-constellation GNSS reception. Multipoint feeding technology provides low phase center variation, while symmetric radiation patterns, wide-angle circular polarization and up to 4 dBi gain support stable low-elevation satellite tracking.
Strong Anti-interference Perfprmance

A pre-filtered low-noise amplifier suppresses out-of-band signals and reduces receiver desensitization. This filtering helps maintain stable GNSS reception in complex electromagnetic environments, supporting satellite tracking and reliable positioning for UAVs, small robots and autonomous vehicles.
Small Size, Light Weight, Low Power Consumption

Measuring 64 × 64 × 13.4 mm and weighing ≤90 g, the antenna offers a low-profile embedded design for compact platforms. Current consumption of ≤50 mA helps limit system power demand, while its compact structure simplifies integration into UAVs, small robots and autonomous vehicles.
