One technology ziphone currently uproar is the GPS, Global Positioning System (GPS) to provide position information and time continuously in various places on earth. Because the GPS can be accessed by a number of users that are not limited to, the GPS is a system that passively. Therefore, the user can only receive satellite signals with the help of GPS Receiver.

Previously, the GPS Receiver is a retired tool. Now, GPS is integrated with mobile phones. Problems faced if the GPS is used for applications in mobile phones is the amount of time required for the determination of position. Meanwhile, Assisted GPS (A-GPS) assistance from the base station in the determination of the position. So that the GPS Receiver can process more rapid, accurate, and efficient.

However, A-GPS functionality on mobile phones has not been optimized by both vendors and mobile phone users. In the end this task will be made an application that allows users to know the position of his mobile phone. Users can also know the position with other mobile phone users to send short messages or sms. Users who want to know the position of mobile phones should make its first registration.

A-GPS system is not feasible to be implemented in Indonesia (especially in Bandung and Jakarta, where the testing system). This system does not generate a short TTFF. TTFF were produced between 10 minutes-1 hour. Motorola E1000 also must LOS with the satellite. The poor performance of A-GPS is caused by the lack of assistance from the network operator. Opinion writers are also strengthened with the statement that the motorola said that the A-GPS service in the Motorola E1000 can not be applied in Indonesia, because Indonesia is not the network operator support.

FindMe positioning systems and mobile phones in the final task is not to have problems later if the network operator supports. To develop further, many applications that can be created with Assisted GPS.
