Development of UWB-IR based low power asset tracking system with precise location information

Abstract

Global Positioning System (GPS) and Global Navigation Satellite System (GNSS) are currently widely used for measurement of real time location of assets in tracking applications. However, in densely cluttered indoor environments, direct line of sight signal from satellite is weak and the received signal is dominated by reflected signals (multi-path signals). This causes the receiver to track the multi-path signals resulting in degraded position information or the signal may be so heavily attenuated that it goes below noise floor of the receiver and makes it difficult for the receiver to detect the signal. There is also
