GNSS Antenna (AX3702)
The AX3702 is a mini survey antenna. It can receive GPS L1/L2, GLONASS L1/L2, and BeiDou B1/B2/B3 signals, which can be used in land survey, marine survey, channel survey, seismic monitoring, bridge survey, container operation, agriculture applications, etc. The AX3702 was calibrated in NGS. Customers can use the antenna for GPS-only or three-constellation navigation applications.
