Introduction

The Harxon HX-CSX633A is a high-performance survey GNSS antenna designed for high-precision positioning and multi-constellation tracking, supporting BeiDou, GPS, GLONASS, and Galileo. Its advanced RF performance ensures stable signal reception, excellent tracking accuracy, and reliable positioning results. With flexible installation options including magnetic mount, screw mount, and pole mount, the HX-CSX633A enables easy deployment across a wide range of surveying, RTK GNSS, reference station, and precision positioning applications.

Key Features

Ruggedized Housing, Easy to Install

HX-CSX633A is designed with brand new structure, enabling easy and flexible installations (magnetic mount, screws mount and pole mount) for many high-precision applications.
High Phase Center Stability

HX-CSX633A features a multi-point feeding deign to achieve greater phase center stability. It effectively improves measurement accuracy and provides better positioning solutions.
Tracking in Challenging Environments

The ability to receive low elevation signals with high gain and wide beam width makes HX-CSX633A an excellent choice for tracking visible satellites under challenging conditions.
Strong Anti-interference Performance

The antenna LNA features an excellent out-of-band rejection performance, which can suppress the electromagnetic interference, providing the stability and reliability of GNSS signals.
