Indoor GPS: System Functionality and Initial Performance Evaluation

Indoor GPS (IGPS) is a newly developed laser based measuring system for large scale metrology. The relative portability, reconfigurability and ease of installation make the IGPS suitable for many industries manufacturing large scale products. The system performance depends on both the components characteristics and their physical configuration. Hence, an important consideration for the IGPS is to characterise its real capabilities, pointing out how they can be influenced by the system's configuration and setup.
