Product Description
RAT is a GNSS measurement antenna that supports the full frequency range and can receive satellite navigation signals at BDS, GPS, GLONASS and Galileo frequencies. It is widely applied in high-precision navigation and positioning scenarios such as geodesy mapping, Marine surveying, and precision agriculture.
Product features
The multi-feed point design is adopted to ensure the performance of right-hand circular polarization and phase center, reducing the influence of measurement errors.
The antenna unit has a high gain, ensuring that the system has a sufficient number of available satellites.
The unique antenna structure design enhances the multi-path suppression performance at low elevation angles and simultaneously increases the maximum antenna gain.
The low-noise amplifier adopts the pre-filter technology, effectively suppressing out-of-band interference signals and enhancing the reliability of the system.
The housing is IP67 protected, providing a guarantee for the antenna to work outdoors for a long time.
