    Miniaturized external multi-satellite multi-frequency measurement antenna specification
    创始人2025-01-13

    The TDXL-BA720 is a multi-satellite, multi-frequency GNSS high-precision measurement external antenna that supports the reception of satellite navigation signals from BDS, GPS, GLONASS, and GALILEO systems. It meets the current demands for multi-system compatibility and high-precision measurement and can be widely applied in geodetic surveying, marine surveying, precision agriculture, deformation monitoring and other high-precision navigation and positioning scenarios.

    1、Using multi-feed miniaturized technique, the antenna enables the right circular polarization and phase center performance, as well as minimizes the impact of measuring error;

    2、The antenna unit offers high gain and minimal gain roll-off, providing excellent reception of low elevation satellite signals and ensuring normal reception in severely obscured locations.

    3、The front-end filtering circuit is designed to effectively reduce the interference of signal reception, ensuring measurement accuracy.
