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 ensure alignment of the phase center and geometric center, minimizing impact on measurement accuracy. The antenna unit provides high gain and wide beamwidth, ensuring reliable signal reception at low elevation angles and maintaining satellite acquisition under challenging obstruction conditions. Designed for durability with resistance to high and low temperatures, waterproofing, and protection against environmental damage.
