7Semi ZED-F9P Dual-band GNSS RTK SMA Modem

The 7Semi ZED-F9P Dual-band GNSS RTK SMA Modem is a high-precision satellite positioning module designed for centimeter-level accuracy using Real-Time Kinematic (RTK) technology. Powered by the u-blox ZED-F9P GNSS engine, it supports dual-frequency (L1 and L2) signals from multiple satellite constellations including GPS, GLONASS, Galileo, and BeiDou. The module offers multi-band and multi-constellation tracking for reliable, high-accuracy positioning even in challenging environments. With multiple communication interfaces and SMA connectors for external antennas, this modem is ideal for robotics, surveying, drone navigation, and precision agriculture applications.
