TDOA Multi Station Spectrum Detection Device

Unmanned Aerial Vehicle (UAV) signal localization is executed via a Time Difference of Arrival (TDOA) network consisting of compact outdoor monitoring receivers. This setup typically requires the deployment of at least four mobile or portable stations, spaced between 300 meters and 1 kilometer apart. Each station performs dual functions: conventional signal monitoring and TDOA-based positioning.

TDOA localization determines a signal source's coordinates by measuring the relative time delay as a signal reaches different receivers. While calculating absolute travel time is technically demanding, comparing arrival time differences allows for the construction of hyperbolas, where the stations act as foci and the time differences define the major axes. The intersection of these hyperbolas pinpoint the exact location of the UAV signal.
