Abstract
A system for determining a geographical position of a transmitting device is disclosed. In embodiments, the system includes a concentrator device and a plurality of sensors. In embodiments, each sensor may be configured to: receive an emitter signal from a transmitting device; generate a demodulated sequence of the emitter signal; generate a time-of-arrival (TOA) estimate of the emitter signal; and transmit the demodulated sequence and the TOA estimate to the concentrator device. In embodiments, the concentrator may be configured to: receive a first demodulated sequence and a first TOA estimate (TOA) from a first sensor; receive a second demodulated sequence and a second TOA estimate (TOA), from a second sensor; determine a first arbitrary timing offset (ATO) between the first demodulated sequence and the second demodulated sequence; and determine a first differential TOA estimate (TOA) between the first sensor and the second sensor.
