The AX4E03 GNSS antenna is a high precision compact GNSS antenna for aviation, which is capable of receiving signals from GPS, GLONASS, Galileo, BeiDou, QZSS, IRNSS, as well as L-Band correction service. The ability to receive low elevation signals with high gain and wide beam width makes AX4E03 a suitable choice for tracking visible satellites and provide stable and precision GNSS data under different flight attitudes.
