AX3702 is a mini survey antenna. It receives GPS L1/L2, GLONASS L1/L2 and BDS B1/B2/B3 frequencies, which can be used in land survey, marine survey, channel survey, seismic monitoring, bridge survey, container operation, agriculture applications, etc. AX3702 was calibrated in NGS. Customers can use the antenna for GPS-only or three-constellations applications.

It has high gain and wide beam width to ensure that the satellite performs well at receiving signals at low elevation angle. The phase center of this antenna remains constant as the azimuth and the elevation angles of the satellites change. Signal reception is unaffected by the rotation of the antenna or satellite elevation, so placement and installation of the antenna can be completed with ease.

Key Features

  • Supports multi-constellation and multi- frequency
    • GPS L1/L2, GLONASS G1/G2 and BDS B1/B2/B3
  • Multi-path rejection board inside eliminates multi-path influence to measurement error.
