Satellite-based or network-based positioning technologies make it possible to determine the geographic location of these wireless electronic devices and their users (e.g. location-based services for users of mobile telephones use such positioning technologies). Location sources can also include computer-based models, schedules or calendars that give a person's expected location depending on the date and time.
