UA92
Choke Ring Antenna
The UA92 is a multi-system full-frequency reference station antenna covering BDS, GPS, GLONASS, and GALILEO. It adopts a unique choke structure design. The product has a stable phase center, good multipath suppression effect, high positioning accuracy, and low elevation angle reception.

Powerful Satellite Tracking Capacity
Obtain all available and reliable data sources, with total channels and all signals (GPS, BDS, GLONASS, GALILEO, IRNSS, QZSS, and SBAS) of GNSS tracking.

High Gain (≤5.5 dBi)
Experience strong GNSS satellite tracking ability, and make your measurement work and data more reliable due to the excellent antenna gain.

High Phase Center Accuracy
Experience sub-millimeter phase center accuracy with higher stability.

Rugged Design for Harsh Environments
Use it for many years with IP67 design, which is 95% protected against solid objects like dust and sand, and it has been tested to work for at least 30 minutes under 15 cm to 1 m of water.

Excellent Multipath Suppression Effect
No longer need to worry about interference by multipath due to the unique choke coil design.

Multiple Applications
The UA92's compact size and light structure can be used for mechanical control, deformation monitoring, Marine mapping, and other fields.
