Last years have been characterized by an incredible growth in mobile computing capabilities and sensing technologies, which can leverage the deployment of many location-based applications, ranging from pedometers to navigation system. This work deals with an Inertial Navigation System (INS) able to support users in the navigation in an unknown indoor environment by continuously calculating their motions and their position. The proposed solution is based on integrated use of movement and position sensors. Unfortunately, applications that rely on the use of measures coming from orientation sensors, such accelerometers and digital compasses, are affected by external magnetic interferences thus resulting in inaccurate directional information. This paper focuses on this problem by investigating the use of the gyroscope as the primary determinant of orientation.

Abstract

Last years have been characterized by an incredible growth in mobile computing capabilities and sensing technologies, which can leverage the deployment of many location-based applications, ranging from pedometers to navigation system. This work deals with an Inertial Navigation System (INS) able to support users in the navigation in an unknown indoor environment by continuously calculating their motions and their position. The proposed solution is based on integrated use of movement and position sensors. Unfortunately, applications that rely on the use of measures coming from orientation sensors, such accelerometers and digital compasses, are affected by external magnetic interferences thus resulting in inaccurate directional information. This paper focuses on this problem by investigating the use of the gyroscope as the primary determinant of orientation. Several tests have been carried out showing how the proposed method is able to correct the error introduced by the gyroscope both in static position and undergoing rotation, and thus, it is able to provide better orientation information than the compass.
