About the Trimble AX940 smart antenna

The smart antenna (also referred to as a receiver) is sold in two hardware configurations:

  • AX940 GNSS

  • AX940i GNSS+Wi-Fi/Bluetooth+INS

NOTE – References to Wi-Fi/Bluetooth or INS in this documentation relate to the AX940i smart antenna, not the AX940 smart antenna.

The AX940 smart antennas are designed to be robust and waterproof. The smart antennas can be used as either a base station or a rover. The Trimble AX940i smart antenna leverages the power of Trimble Maxwell™ 7 processing technology. The smart antennas support triple-frequency from both GPS and GLONASS constellations plus dual‑frequency from BeiDou and Galileo.

The smart antennas provides reliable operation in all environments, and a positioning interface to an office computer, external processing device, or control system. You can control the smart antennas through a serial or ethernet port using API commands (see API documentation - Introduction to the receiver interface protocol) or the web interface (see Receiver web interface).

The Trimble AX940i GNSS-Inertial smart antenna also combines a triple-frequency GNSS receiver with inertial sensors and high-performance antenna in a rugged smart antenna design for vehicle-mounted applications. This enables OEM and system integrator customers to rapidly integrate high-accuracy GNSS-Inertial into their applications. The receiver is also suited for applications that require precise heading and attitude information in addition to position.
