What Is Survey Antenna ?

GNSS survey antenna is an active antenna that can use global satellite positioning technology to obtain the information of the earth's gravity field and the ground geographical environment.
The GNSS survey antenna obtains accurate location information through the connection with the satellite, and then transmits it to the data communication system and transmits the monitored data to the control system. The control system corrects the surveying and mapping data and sends it to the user through RTK (RealTimeKinematic) real-time dynamic measurement technology.
CAZN RF Branch has a group of experienced engineers who have developed high-precision, stable phase center, high gain, long transmission distance and high compatibility antenna products to meet market needs.

Main Features Of The Survey Antenna

• The single-layer ultra-wideband design is adopted to minimize the phase center elevation difference in the entire working frequency band;
• High gain, small gain roll-off, good reception of low-elevation satellite signals, ensuring that survey antenna satellites can still be connected in some serious occlusion occasions;
• The low-noise amplifier adopts multi-stage filtering technology to effectively suppress out-of-band interference signals and improve the reliability of the system;
• The parasitic network path suppression technology effectively reduces the influence of multipath signals on the measurement accuracy;
• Waterproof and anti-ultraviolet cover provides a guarantee for the antenna to work in the field for a long time.
