Localization is a technical to find the location of a target, such as a worker walking in a plant. For outdoor localization, satellite-based global positioning system (GPS) is commonly used. GPS does not provide good accuracy for indoor localization due to the complicated indoor environment that affects the GPS signal propagation. Currently, there are two […]

Using inertial measurement units (IMUs) has been one of the main techniques for indoor localization. In many cases, this type of methods uses accelerometer, gyroscope, and/or magnetometer that are available in commercial mobile devices, such as smart phone. One main advantage of using this type of techniques is that no separate infrastructure deployment is needed. […]
