1. In a system for characterizing the movement of a golf ball assembly on a golf range having lateral extents, a method comprising:

  • configuring the golf ball assembly for transmitting a ball signal at least from a landing impact location on the golf range based on a detected proximity of the golf ball assembly to a surface of the ground;

    distributing a plurality of at least four ground transceivers across the lateral extents of the golf range;

    determining positional coordinates of at least the four ground transceivers such that the four ground transceivers form a group of ground transceivers that are at known locations;

    receiving the ball signal at each one of the ground transceivers in timed relation to one another;

    identifying a selected one of the ground transceivers as a reference transceiver such that the arrival time of the ball signal at the selected ground transceiver serves as a reference arrival time;

    establishing a set of arrival time differences including a difference in arrival time of the ball signal at each of the other three ground transceivers as compared to the reference arrival time at the reference ground transceiver; and

    determining a landing position of the golf ball assembly in two dimensions with respect to the lateral extents of the golf range based on the set of arrival time differences.
