Location correction through differential networks system

A base station having a reference geoposition, the base station comprising:

• a global positioning system (GPS) receiver configured to receive a respective time-stamped first set of GPS data from each of a plurality of GPS satellites;
• a chipset or a processor in communication with the GPS receiver;
• and
• memory on which is recorded instructions that, when executed by the processor, causes the base station to:
• establish an internet connection with a portable mobile device, wherein the portable mobile device is a cell phone, a tablet computer, or other portable electronic device;
• receive an accuracy improvement request signal from the portable mobile device;
• receive a second set of GPS data from the portable mobile device over the established internet connection, the second set of GPS data describing a geoposition of the portable mobile device and having a time of collection that coincides with a time of collection of the time-stamped first sets of GPS data, wherein the first and second sets of GPS data each includes respective code phase data, carrier phase data, and pseudo-range data from each of the GPS satellites;
• generate, via a predetermined GPS position correction technique, a corrected geoposition of the portable mobile device using the processor and the first and second sets of GPS data;
• and
• transmit the corrected geoposition of the mobile device to the portable mobile device and an external response system.

A portable mobile device comprising:

• a global positioning system (GPS) receiver configured to receive a respective time-stamped set of GPS data from each of a plurality of GPS satellites;
• a chipset or a processor in communication with the GPS receiver, wherein the portable mobile device is a cell phone, a tablet computer, or other portable electronic device, and wherein the chipset or processor and the GPS receiver of the portable mobile device together provide a first GPS accuracy or resolution;
• and
• memory on which is recorded instructions that, when executed by the processor, causes the portable mobile device to:
• receive a user input indicative of a request for improved GPS location accuracy of the portable mobile device;
• responsive to receipt of the user input, establish an internet connection between the portable mobile device and a base station having a reference geoposition of a second GPS accuracy or resolution that exceeds the first GPS accuracy or resolution of the portable mobile device;
• transmit an accuracy improvement request signal to the base station over the established internet connection, in response to the user input to the portable mobile device;
• receive another time-stamped set of GPS data from the base station over the established internet connection describing the reference geoposition of the base station with a second GPS accuracy or resolution that exceeds the first GPS accuracy or resolution of the mobile device, wherein a time of collection of the respective time-stamped sets of GPS data from the portable mobile device and the base station coincide, and the time-stamped sets of GPS data each includes respective code phase data, carrier phase data, and pseudo-range data from each of the GPS satellites;
• generate, via a predetermined GPS position correction technique, a corrected geoposition of the portable mobile device using the processor and the first and second sets of GPS data;
• and
• automatically request execution of a control action of an external response system using the corrected geoposition, including transmitting the corrected geoposition to the external response system.
