    ER-MA-03 GNSS Measurement Antenna 


    The ER-MA-03 GNSS Measurement Antenna is specially designed for millimeter-level positioning needs in land and marine surveys. The ER-MA-03 antenna supports all current major GNSS signals, including GPS, GLONASS, BeiDou, and Galileo. The antenna is suitable for the fields of measurement, RTK positioning, high-precision navigation, and mechanical control. The product has excellent anti-multipath performance, stable phase center, and high signal-to-noise performance at low elevation angles. The antenna can also work normally in complex environments. The aluminum base of A45 can adapt to the harsh marine environment, and the radome has excellent protection performance, which can ensure that it will not be damaged when dropped from the 2m-high support pole.
