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 is widely used in geodetic surveying, road construction, ocean surveying, terminal container operations, and similar environments. The antenna utilizes a multi-feed point design to ensure alignment of the phase center and geometric center, minimizing impact on measurement accuracy. The antenna element provides high gain and wide beamwidth, enabling reliable signal reception at low elevation angles and consistent satellite acquisition even under challenging signal obstruction conditions. It is designed for resistance to high and low temperatures, is waterproof, and includes a protective cover.
