A positioning system has an initiator device configured for emitting a high-speed wireless signal, at least one reference device configured for receiving the high-speed wireless signal and emitting a low-speed wireless signal after receiving the high-speed wireless signal, at least one target device each having one or more components for receiving the low-speed wireless signals, and at least one engine configured for determining the position of each of the at-least-one target device by calculating the distance between the target device and each of the at-least-one reference device based on at least the times-of-arrival of the low-speed wireless signals, each time-of-arrival being the time that the corresponding low-speed wireless signal being received by the target device, and determining the position of the target device based on the calculated distances.

A method and system for using GPS signals and a magnetic field to track an underground magnetic field source. A tracker having an antenna for detecting the magnetic field and a GPS receiver is coupled to a processor. The magnetic field is used by the antenna to direct the tracker to a field null point. Once multiple measurements of the field are taken, the changes in signal strength as the absolute position of the tracker is changed, are used to determine whether the closest field null point is in front of or behind the underground beacon. The position and depth of the beacon can then be estimated.

An identification system includes an identification device and a communication device. The identification device is attached to an article and including a sensor. The identification device is configured to operate in a plurality of modes and configured to switch between modes of the plurality of modes based on one or more conditions of a surrounding environment sensed by the sensor. The identification device is configured to send data to a server. The communication device of a user of the identification system is configured to receive data including location data of the identification device from the server using short message service protocols or messages through a signaling channel.

Disclosed are devices, systems and methods for combining observations obtained at two different mobile devices attached to a human user for performing a navigation operation. For example, observations of a signal acquired at a first mobile device may be selected for computing a position fix based, at least in part, on a utility indicator associated with the observations.

A method for estimating the location of a wireless terminal at an unknown location, such as within a building. A location engine using the disclosed method receives and uses samples of barometric pressure measured by the wireless terminal to generate a characterization of a pressure wave in the vicinity of the wireless terminal. The location engine generates an estimate of the location of the wireless terminal based on the characterization of the pressure wave and, in some cases, the location of the source of the pressure wave, such as a building's door that is opening or closing. The location engine also bases the estimate of the wireless terminal's location on a propagation characteristic of the pressure wave, such as its speed of propagation.
