    Built-in single-FREQUENCY BDS positioning antenna specification
    创始人2025-01-15

    TDXL-BSA501-B is a high-precision measurement built-in antenna designed for supporting BDS single-frequency B3I. The antenna meets the current demands for compatibility with the BDS positioning system and high-precision measurement requirements. It could widely applicable in geodetic surveying, marine surveying, precision agriculture, deformation monitoring and other high-precision navigation and positioning scenarios.

    1、Using multi-feed miniaturized design, 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 pre-filter circuit design can effectively reduce interference with signal reception, ensuring measurement accuracy.
