Multi-Band GNSS antenna 38dBi GPS GLONASS Beidou Galileo
Product Introduction
Multi-band GNSS antenna, designed to support multiple satellite navigation systems including Beidou II, GPS, GLONASS and GALILEO. With its double-layer, multi-feed point design, the antenna ensures excellent reception of navigation signals from these systems, making it the perfect solution for high-precision navigation and positioning applications.
One of the key features of our multi-band GNSS antennas is their built-in low noise amplifier and multi-stage filter. This advanced technology not only provides excellent out-of-band suppression, but also provides strong anti-interference capabilities, allowing the antenna to operate flawlessly even in harsh electromagnetic environments. This antenna is a real game changer as it meets the current demands for multi-system compatibility and high-precision measurements.
Our antenna is designed using multi-feed point technology to ensure right-hand circular polarization and phase center performance, minimizing the impact of measurement errors. In addition, the antenna unit has high passive gain and wide pattern beam to ensure reception of signals at low elevation angles. The pre-filtering function significantly reduces the noise figure and enhances the antenna's anti-interference ability.
To further improve its reliability, our multi-band GNSS antennas are IP67 rated. This ensures that the antenna can withstand the harshest field conditions and continue to provide excellent performance over an extended period of time. Whether you need aerospace applications, precision agriculture, vehicle positioning or precise navigation of drones, our antennas are ideal.
