    External full-band measurement antenna specification
    创始人2025-01-13

    TDXL-BA802 is a high-precision external measurement antenna designed for  supporting the reception of satellite navigation signals from BDS, GPS, GLONASS and Galileo systems, as well as Satellite-Based Augmentation System (SBAS) L-band. 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、It is equipped with front-end power limiting and anti-burnout protection (≥2W), ensuring that the antenna remains undamaged in strong electromagnetic fields.

    5、The IP67 waterproof and dustproof design and its resistance to salt spray for 96 hours provide protection for the antenna's long-term outdoor operation.
