If the iOS devices you manage in Device Manager have a location services policy applied and you configure geo-tracking, you can view the locations of the device over the time you configured in the location services policy. Geo-tracking enables you to track an iOS device over periods of up to six hours at a time. You can view the geographical location of a device and its movement and you can view the device location on Google Maps. If you want to specify individual parameters for your GPS tracking (as opposed to just activating it), you need to deploy a geo-tracking policy. If you choose to keep the default values, you can enable tracking immediately.
