Research And Implementation Of Multifunctional Positioning Based On The Android Mobile Phone

With the rapid development of mobile terminal platform technology,continuous extension of the application of GPS,and Trunked Communication System being perfected,GPS function in the smart client to integrate with Trunked Communication System has become a future direction in exploiting mobile applications.It achieves the real-time communication between multi-users with location information.In this paper the author developed an Android applicati on based on Android,as a new smartphone client,has its great openness and expansibility of hardware and software.The author first introduces the research background and current realization of the smart client of Trunk ed Communication System.According t o the needs of the users,the paper gives the positioning module detailed design and implementation process.The GPS development based on Android platform to cooperate with Trunked Communication System has its naturally potential and prospect.The user achieves self-positioning through the client software on mobile phone,along with sending requests to the server to access location information of other members in the group.With the growing demand for indoor location services,the development of wireless indoor positioning technology,and the popularity of smart phone applications,the indoor positioning technology based on smart phone has become the new research hotspot.This paper mainly studied the high-precision indoor positioning technology based on received signal strength indicator(RSSI)of Bluetooth low energy(BLE).A demo system is developed and tested with Android operating system.
