The eSurvey UA91 adopts a high-gain broadband antenna to receive GNSS signals such as GPS, BDS, GLONASS, Galileo, IRNSS, QZSS, and L-Band. The scheme of multi-stage 3D choke coils with a symmetrical distribution is adopted to achieve higher phase center stability and excellent anti-multipath interference performance. It has excellent performance and the phase center coincides with the mechanical center.
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
Temperature Performance
The UAST works in the range of temperatures from -55°C to +85°C and stores in -55°C – +90°C
High Phase Center Accuracy
Experience 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
Due to the unique 30 choke coil design and electrostatic protection against eight liv of air and four key of static electricity, no longer a need to worry about interference by multipath.
High Gain
The UASI uses a high-gain wide-band dual-band multimode GNSS measuring antenna to achieve coverage of the GNSS signal reception
