    Product description

    BGG39 multi-system active antenna is a survey antenna integrating GPS, Glonass, Beidou and other satellite signals, which can be widely used in geodesy, bridge construction, marine surveying, underwater topography survey and other occasions.

    The antenna adopts a multi-feed point design to ensure that the phase center and geometric center of the antenna coincide, improving the accuracy of measurement. Built-in low-noise amplification module, through multi-stage filter to filter out interference signals, to ensure normal operation in harsh electromagnetic environment.
