TOPGNSS AN600 is a multi satellite and multi frequency GNSS measurement antenna that supports L1 or L2 or L5 satellite navigation signal reception in the Beidou second-generation, GPS, and GLONASS frequency bands. It can be widely used in geodetic mapping, oceanographic survey, precision agriculture, Deformation monitoring and other high-precision navigation and positioning occasions. The bottom of the product is equipped with 3 magnets and standard 5 or 8-11 large nuts for easy installation. Adopting a 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 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 provides protection for the antenna to work in for a long time.
