TOPGNSS AN600 is a multi satellite and multi frequency GNSS measurement antenna that supports L1/L2/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 5/8-11 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.
