The plurality of beams define a field of view of the phased antenna array, the field of view having a plurality of cells and each of the plurality of beams is associated with one of the plurality of cells within the field of view. A processing device detects the wireless device within the field of view and determines a coarse geographic location of the wireless device within the field of view of the wireless device when the wireless device is within the field of view, or within a cell. The system further determines a fine geographic location for the wireless device based on frequency offset (due to Doppler) and signal flight time."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Geolocation of radio frequency devices using spaceborne phased arrays","description":"A communication system has a phased antenna array configured to communicate via a plurality of beams with a wireless device, such as user equipment (e.g., a smart phone).
