In an embodiment, a signal is received at a ground station from the emitter and relayed by the geostationary satellite. The signal is received at the ground station at a plurality of time instances and has a plurality of observed frequencies, one for each time instance. A plurality of lines of position are determining based on the plurality of observed frequencies. The transmit location of the emitter is determined based on at least one intersection among the plurality of lines of position."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Determining transmit location of an emitter using a single geostationary satellite","description":"The present invention provides a method and apparatus for determining the transmit location of an emitter using a single geostationary satellite.
