Harxon HX-CSX633A GNSS Survey Antenna


GPS L1/L2/L5 + GLONASS L1/L2/L3 + Galileo E1/E5a/E5b/E6 + BeiDou B1I/B2I/B3I/B1C/B2a/B2b + QZSS L1/L2/L5/L6 +IRNSS L5 + SBAS L1/L5 L-band



The HX-CSX633A from Harxon is a high-precision GNSS survey antenna which offers superior satellite signal tracking, including GPS, GLONASS, Galileo and BeiDou. It enables easy and flexible installations (magnetic mount, screws mount and pole mount) for many high-precision applications.

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

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

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.


  • Ruggedized Housing, Easy to Install
  • High Phase Center Stability
  • Tracking in Challenging Environments
  • Strong Anti-Interference Capabilities
