Indoor GPS (iGPS™)
Indoor GPS is a recent laser-based distributed measurement system for dimensional measurements of large-size objects. The performance of iGPS™ depends both on the characteristics of the system components and their physical configuration. Hence, it is important to characterise its real capabilities and point out how they can be influenced by the system configuration and calibration. This chapter presents the system architecture, its hardware and software working principles and provides an exploratory evaluation of the system’s metrological performance, both in static and dynamic conditions.
