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

    TDXL-BA1500 is a high-precision external measurement antenna designed for  supporting the reception of satellite navigation signals from BDS, GPS, GLONASS and Galileo systems. The antenna features excellent resistance to multipath effects, stable phase center, high positioning accuracy, and effective reception at low elevation angles. It is suitable for applications like deformation monitoring, networking requirements for unmanned driving base stations and reference stations, and high-precision surveying.

    1、The phase center accuracy is at the millimeter level, ensuring high stability and repeatability of the phase center.

    2、High gain at low elevation angles, with a strong tracking capability for low-elevation satellites, guaranteeing an adequate number of available satellites for the measurement system.

    3、A front-end filtering is designed to effectively suppress out-of-band interference signals. High low-noise amplifier gain, allowing for cable lengths of over 30 meters.

    4、The unique waterproof and dustproof design ensures the core components are completely sealed, allowing for normal operation outdoors over the long term.
