Introduction

Harxon HX-CUX014A (L1+L5) is a compact, high-gain embedded active GNSS antenna for UAVs, small robots and autonomous vehicles. It supports GPS L1/L5, Galileo E1/E5a, BeiDou B1I/B1C/B2a and GLONASS L1 for multi-constellation positioning. Advanced multipoint feeding technology, up to 4 dBi antenna gain and wide-angle circular polarization enable stable phase center performance and 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-profile design and low power consumption simplify integration into space-constrained navigation and positioning systems.

Key Features

Consistent Performance Across GNSS Frequency Bands

The antenna supports GPS L1/L5, Galileo E1/E5a, BeiDou B1I/B1C/B2a and GLONASS L1. Multipoint feeding technology provides low phase center variation, while up to 4 dBi gain and wide-angle circular polarization support reliable low-elevation satellite tracking for precise positioning.
Strong Anti-interference Perfprmance

A pre-filtered low-noise amplifier (LNA) 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.
