摘要：A method and an apparatus using a low Earth orbiting (LEO) satellite signal to augment the Global Positioning System (GPS) for finding a location vector between a GPS ur receiver and a GPS reference receiver. The GPS ur receiver computes a LEO ur-reference carrier pha difference and a GPS ur-reference carrier pha difference for the LEO satellite signal and a GPS satellite signal, respectively, received simultaneously at the GPS ur receiver and the GPS reference receiver. Carrier pha double differences are computed from a difference between the GPS ur-reference carrier phas from two GPS satellites and either the LEO ur-reference carrier phas from two LEO satellites or the GPS ur-reference carrier pha from one GPS satellite and the LEO ur-reference carrier pha from one LEO satellite. The location vector is computed from a difference between the double differences for two satellite geometries. The GPS reference receiver communicates the reference carrier pha data to the GPS ur receiver through the LEO satellite. An ionospheric delay model is determined by tracking the LEO satellite signal as the LEO satellite travers the sky. An optional calibrator corrects for measurement delay in determining the carrier phas in the GPS ur日本七夕
