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.

First claim

What is claimed is:

1 . A method for identifying a location of a mobile device, the method comprising the steps of:
receiving a first set of Global Positioning System (GPS) data at a time, wherein the time is specified by the mobile device; synchronizing, by one or more processors, the time with Coordinated Universal Time (UTC); retrieving, by one or more processors, 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; calculating, by one or more processors, location coordinates of the mobile device using the first set of GPS data and the offset values; and storing, by one or more processors, at least the location coordinates of the mobile device and the synchronized time.

2 . The method of claim 1 , further comprising:
granting, by one or more processors, an application access to at least the stored location coordinates of the mobile device and the synchronized time.

3 . The method of claim 1 , further comprising:
uploading, by one or more processors, at least the location coordinates of the mobile device and the synchronized time as content on a social network.

4 . The method of claim 1 , further comprising:
calculating, by one or more processors, a velocity of the mobile device based on the location coordinates of the mobile device and a set of one or more stored location coordinates; and determining, by one or more processors, a rate at which GPS data is to be collected based on, at least, the calculated velocity of the mobile device.

5 . The method of claim 1 , wherein synchronizing the time with UTC comprises:
synchronizing, by one or more processors, the time with UTC using Network Time Protocol (NTP).

6 . The method of claim 1 , wherein synchronizing the time with UTC comprises:
responsive to the time being different than UTC, adjusting, by one or more processors, the time to UTC.

7 . The method of claim 1 , wherein synchronizing the time with UTC comprises:
responsive to the time being different than UTC, storing, by one or more processors, a difference in time between the time and UTC.

8 . A computer program product for identifying a location of a mobile device, the computer program product comprising:
one or more computer readable storage media and program instructions stored on the one or more computer readable storage media, the program instructions comprising: program instructions to receive a first set of Global Positioning System (GPS) data at a time, wherein the time is specified by the mobile device; program instructions to synchronize the time with Coordinated Universal Time (UTC); program instructions to retrieve 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; program instructions to calculate location coordinates of the mobile device using the first set of GPS data and the offset values; and program instructions to store at least the location coordinates of the mobile device and the synchronized time.

9 . The computer program product of claim 8 , further comprising:
program instructions, stored on the one or more computer readable storage media, to grant an application access to at least the stored location coordinates of the mobile device and the synchronized time.

10 . The computer program product of claim 8 , further comprising:
program instructions, stored on the one or more computer readable storage media, to upload at least the location coordinates of the mobile device and the synchronized time as content on a social network.

11 . The computer program product of claim 8 , further comprising:
program instructions, stored on the one or more computer readable storage media, to calculate a velocity of the mobile device based on the location coordinates of the mobile device and a set of one or more stored location coordinates; and program instructions, stored on the one or more computer readable storage media, to determine a rate at which GPS data is to be collected based on, at least, the calculated velocity of the mobile device.

12 . The computer program product of claim 8 , wherein program instructions to synchronize the time with UTC comprise:
program instructions to synchronize the time with UTC using Network Time Protocol (NTP).

13 . The computer program product of claim 8 , wherein program instructions to synchronize the time with UTC comprise:
program instructions to, responsive to the time being different than UTC, adjust the time to UTC.

14 . The computer program product of claim 8 , wherein program instructions to synchronize the time with UTC comprise:
program instructions to, responsive to the time being different than UTC, store a difference in time between the time and UTC.

15 . A computer system for identifying a location of a mobile device, the computer system comprising:
one or more computer processors, one or more computer readable storage media, and program instructions stored on the one or more computer readable storage media for execution by at least one of the one or more processors, the program instructions comprising: program instructions to receive a first set of Global Positioning System (GPS) data at a time, wherein the time is specified by the mobile device; program instructions to synchronize the time with Coordinated Universal Time (UTC); program instructions to retrieve 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; program instructions to calculate location coordinates of the mobile device using the first set of GPS data and the offset values; and program instructions to store at least the location coordinates of the mobile device and the synchronized time.

16 . The computer system of claim 15 , further comprising:
program instructions, stored on the one or more computer readable storage media for execution by at least one of the one or more processors, to grant an application access to at least the stored location coordinates of the mobile device and the synchronized time.

17 . The computer system of claim 15 , further comprising:
program instructions, stored on the one or more computer readable storage media for execution by at least one of the one or more processors, to upload at least the location coordinates of the mobile device and the synchronized time as content on a social network.

18 . The computer system of claim 15 , further comprising:
program instructions, stored on the one or more computer readable storage media for execution by at least one of the one or more processors, to calculate a velocity of the mobile device based on the location coordinates of the mobile device and a set of one or more stored location coordinates; and program instructions, stored on the one or more computer readable storage media for execution by at least one of the one or more processors, to determine a rate at which GPS data is to be collected b
