High Precision GNSS RTK Survey Antenna for Agriculture and Mapping

AT-603 is a full frequency GNSS measurement antenna that supports L1/L2/L5 satellite navigation signal reception for Beidou II, GPS, and GLONASS. It can be widely used in high-precision navigation and positioning applications such as geodetic surveying and mapping, marine surveying, precision agriculture, deformation monitoring, etc.

Product Application

• It can be widely used in geodetic mapping, oceanographic survey, precision agriculture, Deformation monitoring and other high-precision navigation and positioning occasions.

• Technical Characteristics

• The use of multi feed point design ensures the performance of right-handed circular polarization and phase center, reducing the impact of measurement errors;

• The antenna unit has high gain and good reception effect for low elevation satellite signals, ensuring a sufficient number of available satellites in the system;

• The low noise amplifier adopts pre filtering technology to effectively suppress out of band interference signals and improve system reliability;

• The IP67 protection of the outer shell provides protection for the antenna to work in the field for a long time.
