Description

  • The antenna part adopts a multi-feed point design and a completely symmetrical antenna structure, with a relatively stable phase center, reducing the influence of the antenna on measurement errors.
  • The antenna gain is high, the pattern beam is wide, and the reception effect of low-elevation signals is good, ensuring that the satellite can be received normally in some severely obstructed occasions.
  • The antenna is equipped with an anti-multipath choke plate, which has an anti-surge design and can effectively suppress strong out-of-band interference signals to ensure antenna reliability.
  • It adopts metal base and anti-ultraviolet upper cover design, which is both beautiful and ensures that the antenna shell does not change color when used outdoors for a long time. It has an IP67 waterproof design.
  • Application

    The B4QA1GGGB antenna can be widely used in surveying and mapping, deformation monitoring, precision Positioning, mobile mapping, construction machinery control and precision agriculture and other fields. It can also be used for military vehicle navigation and positioning when necessary.
    The B37A1GGB antenna can be widely used in surveying and mapping, deformation monitoring, driving test driving training, construction machinery control, precision agriculture, automatic driving, outdoor robots, differential base stations and other industrial applications.
