Abstract:
The increasing requirement of Location Based Services in recent years has become a driving force for the developing of positioning technology. Firstly, several indoor positioning systems which are widely used at present are introduced and their advantages and disadvantages are analyzed. Then, some key technologies of indoor positioning are introduced. At last, by analyzing the current positioning technology, the trends of indoor positioning are given. It is demonstrated that this hybrid positioning and navigation-communication integrated positioning can improve the positioning accuracy and robustness effectively. The usage of MMW and MIMO technology can improve the measurement accuracy and the anti-multipath ability.
Key words:  Indoor positioning  Positioning system  Positioning technology  TC-OFDM
