Improvement for mobile positioning systems applying a gyroscope

Abstract

Nowadays, a huge amount of mobile devices are equipped with a number of inertial sensors such as magnetometer, accelerometer and gyroscopes. Today's positioning systems such as GPS or GLONASS are not able to determine the precise position inside the buildings, because of the lack of signal from the satellites. In recent years, the interest in context awareness of mobile devices has increased significantly. Several positioning techniques for indoor navigation have been proposed with the usage of Bluetooth or WLAN. Due to the fact that those systems are very prone to any environmental changes the necessity for enhancement arises. This chapter presents the performance of gyroscope embedded in smartphones. The experiments have been performed in-order to present the possibility of distance calculation with the usage of gyroscope. The gathered results show that gyroscope could be a great enhancement for indoor positioning systems.
