The other one is used for the U.S. military that accuracy is relatively high. GPS can not determine the user. Is one-way communication, such as radio. In other words, whether someone receives is unknown. However, the location information of smart phones are being exposed. Smart phones are operate on location-based services. Location-based services using GPS technology. However, the one-way communication to GPS, the location information out of what could?
