News editors obtained the following quote from the background information supplied by the inventors: "Global positioning systems (GPS) typically consist of a device including a GPS receiver and multiple GPS satellites. The GPS receiver is configured to receive and decode GPS signals broadcast from the GPS satellites in order to determine a location of the device. Each of the GPS satellite signals are transmitted with a satellite-specific encoding, which can be used by a GPS receiver to identify the broadcasting GPS satellite. The GPS receiver is able to calculate the location of the device by decoding the satellite signal, identifying the broadcasting GPS satellites, and performing a series of computations on the data extracted from the decoded signals.
"Many devices today include GPS receivers and support applications that provide location based services. Typically, the location based applications rely on location information to provide these services. Devices may obtain the location information from one of a variety of sources, including GPS receivers, cell-tower signals, FM radio signals, and/or WiFi signatures. While GPS receivers often provide the most accurate and reliable location information available to the mobile device, it is often the case that the other sources are preferred. For example, GPS receivers may consume relatively large amounts of power to sample the GPS signals, decode the GPS signals, and perform the calculations necessary to determine the location of the device. Therefore, some devices may have a preprogrammed preference to utilize the less accurate methods."
As a supplement to the background information on this patent application, VerticalNews correspondents also obtained the inventors' summary information for this patent application: "This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter.
"Implementations of a mobile device including a global positioning system (GPS) which can be used to determine a location of the mobile device are disclosed herein. In one example, the mobile device utilizes a server to aid in determining the location of the mobile device. For example, the mobile device includes a GPS receiver and a communication interface in communication with the server. The mobile device may sample GPS signals using the GPS receiver and provide the samples to the server for processing. In one example, the mobile device is configured to perform preprocessing on the samples to compress and/or decode at least some portions of the samples and the server is configured to processes the compressed samples directly without additional decoding. In one particular example, the GPS signal is compressed according to compressed sensing theory.
