1. A method of locating a device, comprising:
- transmitting at least one signal from a first device to a second device;
receiving, by the first device at a first location, a first signal transmitted by the second device in response to the at least one signal;
providing instruction to move the first device from the first location to a second location along a defined path and with a defined rate of motion;
receiving, by the first device at the second location, a second signal transmitted by the second device in response to the at least one signal;
receiving, by the first device at a third location along the defined path between the first and second locations, a third signal transmitted by the second device in response to the at least one signal;
determining the third location based on the first location, the defined path, and the defined rate of motion; and
determining a location of the second device relative to the first device based on the first signal, the second signal, the third signal, the first location, the second location, and the third location.

Abstract
The location of a device may be determined with respect to another device. For example, a locating device may be moved as it measures at least one distance to a target device. The locating device may then generate one or more indications relating to the measured distance or distances. The locating device also may generate one or more indications relating one or more determined directions to the target device. The target device may be moved in a predetermined manner to determine the location of the target device. Each of the devices may employ a single transceiver and a single antenna for the location determination operations.
