Can receive signals in GPS, GLONASS, Galileo, and BeiDou frequency bands. The antenna features high gain, excellent performance at low elevation angles, wide-angle circular polarization, and a stable phase center. It is suitable for high-precision surveying and mapping applications and widely used in geodetic surveying, road construction, ocean surveying, terminal container operations, and similar environments. The antenna employs a multi-feed point design to align the phase center with the geometric center, minimizing antenna-related measurement errors. The antenna unit provides high gain and wide beamwidth, ensuring reliable signal reception at low elevation angles and stable satellite acquisition under challenging obstructed conditions. It is designed for high and low temperature resistance, waterproofing, and durability.
