A Personal Navigation Test Platform Based on Low-Cost Inertial Components

J. DeChiaro, C. Strus, W.R. Michalson

Abstract:	It is envisioned that personal navigation will play an important role in systems which combine the characteristics of communications networks with positioning technologies to create systems capable of performing location aware computing. Such systems are anticipated to have an important role in applications, such as firefighter safety and in-home wireless healthcare systems, where GPS measurements may be sporadic, or simply unavailable. By incorporating low-cost inertial components into these personal navigation systems, it may be possible to maintain reasonable position information during periods when an ad hoc deployed positioning and communications network is unavailable due to network faults or reconfiguration. This paper discusses the design and implementation of a platform for evaluating inertial navigation components and algorithms for performing personal 3D navigation. This system consists of 3-axis magnetometers, accelerometers and angular rate sensors and allows time-stamped data to be collected and downloaded to a PC for post-processing. The post-processing software consists of a graphical user interface for inspecting the data collected and for computing the 3D trajectory of the device. Assessments of the data collected for a variety of tests will be made.
