The JS-YAC155N is a high-precision integrated antenna, covering L1+L2 frequency bands for GPS, GLONASS, BDS, and GALILEO, while also integrating 4G and Bluetooth antennas. Designed for multi-system compatibility in surveying equipment, it offers low-elevation gain, wide-angle circular polarization, and a stable phase center. This ensures reliable signal reception at low elevations, enabling rapid satellite acquisition and stable GNSS navigation in complex, obstructed environments.
