Research progress of smart phone positioning and navigation sensors

Abstract

Smart phone has gradually become an indispensable mobile device in people's life, and its built-in sensors develop rapidly with the popularity of smart phones. A variety of sensors built in smart phones can provide different positioning sources for indoor positioning, so as to provide convenience for people's activities in large public places. Nowadays, multisensor indoor positioning technology based on smart phones has become a research hot spot, such as indoor visual positioning technology developed by Google and ibeacon indoor positioning technology based on low-power Bluetooth launched by apple. This paper summarizes the development status of smart phone built-in sensors for indoor positioning, sorts out the new smart phone built-in sensors of several popular mobile phone brands in the current market, expounds the sensors for indoor positioning in smart phone sensors and related positioning technologies, and finally looks forward to the future development of smart phone positioning and navigation sensors in the field of positioning.
