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 low-noise amplifier adopts a front-filtering scheme, which can effectively suppress strong out-of-band interference signals and ensure antenna reliability.
  • The shape is designed with low wind resistance, and the shell is designed with high-strength, high-environment adaptability materials to ensure that the antenna can be used in high-altitude and high-speed environments.

    • Application

    It can be widely used in fields such as navigation scheduling, tracking monitoring, positioning and speed measurement. The appearance design of low wind resistance makes it especially suitable for the positioning and speed measurement of high dynamic carriers, such as aviation, high-speed rail, etc.
