Descriptions
The S440 is a full GNSS band active antenna. It is a measurement antenna that integrates GPS, Glonass, Beidou2, Galileo and other satellite signals.
The antenna adopts multi-feed point design to ensure that the phase centre and geometric centre of the antenna coincide and improve the accuracy of measurement. The high gain of the antenna unit and the wide directional beam ensure that the antenna can still receive stars normally in some heavily obscured areas. The antenna is equipped with a multipath choke plate, which effectively reduces the influence of multipath on the measurement accuracy. Built-in low-noise amplification module, filtering the interference signal through multi-stage filter to ensure normal operation in harsh electromagnetic environment.
