Abstract

See full text

A geolocation system includes an originator device configured to transmit a first wireless signal to a transponder device. The transponder device is configured to transmit a second wireless signal to the originator device. The system includes at least one observer device configured to receive the first wireless signal from the originator device and receive the second wireless signal from the transponder device. The system also includes a first processor configured to calculate a transactional difference range at the at least one observer device based on the first wireless signal received at the observer device and the second wireless signal received at the observer device. A corrected transactional difference range value may be calculated by subtracting a time-of-flight of the first wireless signal from the originator device to the transponder device from the transactional difference range. A method of performing geolocation using a transactional difference range is also disclosed.
