GNSS survey antenna HX-CSX633A

Important functions

• Support for GPS, GLONASS, Galileo, BeiDou, QZSS, IRNSS and SBAS signal reception
• Stable phase center guarantees positioning accuracy in the millimeter range
• Strong interference immunity for demanding operating environments
• Robust housing, flexible installation options, waterproof according to IP67

Robust housing, easy installation

The HX-CSX633A is designed with a new structure that allows flexible and easy installations (magnet mount, screw mount and post mount) for a wide range of high-precision applications including agricultural vehicles, small robots and surveying applications. It is housed in a compact and robust housing that provides protection against dust, rain and sunlight to IP67 standards. It can withstand shock and vibration and delivers reliable performance even in harsh environments.

High phase center stability

The HX-CSX633A features a multipoint feeding design that enables higher stability of the phase center. This improves measurement accuracy and provides better positioning solutions.

tracking in difficult environments

The ability to receive signals at low elevation with high gain and wide beamwidth makes the HX-CSX633A an excellent choice for tracking visible satellites in difficult environments. It provides precise positioning solutions and reliable data and can be used in challenging conditions such as forests or construction sites where high precision is required.

Strong immunity to interference

The antenna's LNA provides excellent out-of-band noise rejection, which suppresses electromagnetic interference and ensures the stability and reliability of GNSS signals. It also effectively prevents link drops when receivers operate in complex electromagnetic environments such as communication base stations or urban areas.
