Abstract

It has been considered a fact that GPS performs too poorly inside buildings to provide usable indoor positioning. We demo raw measurements and results from a measurement campaign which show that using state-of-the-art receivers GPS availability is good in many buildings with standard material walls and roofs: The root mean squared accuracy of the measured positions is below five meters in wooden buildings and below ten meters in most of the investigated brick and concrete buildings. Lower accuracies, where observed, can be linked to either low signal-to-noise ratios, multipath phenomena or bad satellite constellation geometry. A comprehensive analysis of the measurement campaign appears as full paper in Pervasive 2010, titled Indoor Positioning Using GPS Revisited.

In this demonstration we present the campaign analysis results with an emphasis on visualization and animation.
Another focus of this demonstration lies on depicting the visualization tools and methods chosen for empirically analysing GNSS indoor performance.
