Abstract
A method and apparatus for locating position of a GPS device is described. In one example, a method for provisioning a mobile device with a model for determining a position of the mobile device in at least one geographic area is provided. The method includes obtaining an estimate of the position of the mobile device, forming one or more satellite orbit models from the estimate and a wide area model, and sending the at least one satellite orbit model to the mobile device. The wide area model is formed from measurements from a plurality of satellites of a Global Positioning System, and the measurements are obtained by a plurality of reference stations.
Claims24
A method for provisioning a mobile device with a model for determining a position of the mobile device in at least one geographic area, the method comprising:
- forming, by a processor, at least one satellite orbit model and a wide area model formed from measurements from a plurality of satellites of a Global Positioning System, and wherein said at least one satellite orbit model is formed based on measurements obtained by a plurality of reference stations, and wherein the wide area model comprises satellite clocks from said plurality of satellites of the Global Positioning System;
- and
- sending, by the processor, the at least one satellite orbit model to the mobile device.
A method for provisioning a mobile device with a model for determining a position of the mobile device in at least one geographic area, the method comprising:
- receiving by the mobile device from a server at least one satellite orbit model, wherein the at least one satellite orbit model is formed from an estimate of a position of the mobile device, and wherein the at least one satellite orbit models is formed from measurements obtained by a plurality of reference stations.
A system for provisioning a mobile device with a model for determining a position of the mobile device in at least one geographic area, the system comprising:
- a first device for obtaining an estimate of the position of the mobile device;
- a server for forming at least one satellite orbit model from the estimate of the position of the mobile device and a wide area model formed from measurements from a plurality of satellites of a Global Positioning System, wherein said at least one satellite orbit model is formed from measurements obtained by a plurality of reference stations, and for sending the at least one satellite orbit model to the mobile device, wherein the wide area model comprises tropospheric delays for said plurality of satellites of the Global Positioning System.
