First Claim
1. A method for identifying a location of a mobile device, the method comprising:
- receiving, at a mobile device, a first set of Global Positioning System (GPS) data at a time, wherein the time is specified by the mobile device;
upon receiving the first set of GPS data, synchronizing, by one or more processors of the mobile device, the time with Coordinated Universal Time (UTC) specified by a first server, wherein;
the first server specifies only unmodified UTC time to the mobile device; and
the synchronizing comprises retrieving, by one or more processors of the mobile device, the unmodified UTC time from the first server;
retrieving, by one or more processors of the mobile device, offset values from an alternate device, wherein;
the offset values comprise one or more values to adjust one or more location coordinates and the offset values are associated with the synchronized time; and
the offset values that are associated with the synchronized time are determined by;
upon receiving a second set of GPS data at the alternate device, synchronizing time specified by the alternate device with unmodified UTC time specified by the first server, wherein the first server specifies only unmodified UTC time to the alternate device;
generating the offset values by comparing a known set of location coordinates of the alternate device to a set of location coordinates calculated using the second set of GPS data; and
associating the synchronized time with the offset values;
calculating, by one or more processors of the mobile device, location coordinates of the mobile device using the first set of GPS data and the offset values; and
storing, by one or more processors of the mobile device, at least the location coordinates of the mobile device and the synchronized time.

Abstract
In an approach for identifying a location of a mobile device a processor receives a first set of Global Positioning System (GPS) data at a time, wherein the time is specified by the mobile device. A processor synchronizes the time with Coordinated Universal Time (UTC). A processor retrieves offset values, wherein the offset values comprise one or more values to adjust one or more location coordinates based on the synchronized time, and wherein the offset values are determined by comparing a known set of location coordinates to a set of location coordinates calculated using another set of GPS data. A processor calculates location coordinates of the mobile device using the first set of GPS data and the offset values. A processor stores at least the location coordinates of the mobile device and the synchronized time.
