Multi star full frequency RTK GNSS antenna
Product Introduction
The full star full frequency satellite navigation antenna has below features:
small size,
high-precision positioning,
High gain,
strong anti-interference ability.
The antenna design with the multi-feed so the phase center is stable. At the same time, the antenna is also equipped with a multi-path choke plate, which effectively avoids the influence of signal interference on navigation accuracy by suppressing multi-path signals.
The anti-surge design can effectively resist strong external interference and ensure the stability and safety of navigation signals.
In addition, this antenna has a wide range of application scenarios. Whether it is geodetic surveying, oceanographic surveying, waterway surveying, or earthquake monitoring, bridge construction, landslides, terminal container operations, etc., it can bring accurate and efficient navigation services to all walks of life.
