GN-GBG07 is a Samsung seven-frequency survey antenna that integrates BD B1&B2&B3, GPS L1&L2 and GLONASS G1&G2. It can be widely used in geodetic surveying, bridge construction, ocean surveying, underwater topographic surveying and other occasions. The antenna adopts a multi-feed point design to ensure the coincidence of the antenna phase center and geometric center and improve the accuracy of measurement. Built-in low-noise amplifying module, using front and multi-stage filters to filter out interference signals to ensure normal operation in harsh electromagnetic environments. Small size and light weight.
