This paper investigates the role of quantization in the Received Signal Strength Indicator (RSSI) information used for fingerprinting (FP) applications. One of the common drawbacks of FP is the large data size and consequently the large search space and computational load as a result of either vastness of the positioning area or the finer resolution in the FP grid map: this limits the application...
Indoor positioning with Pseudolites consists of deploying a network of terrestrial transmitters which have the same function as the Global Navigation Satellite Systems (GNSS) outdoor. In this paper, we propose an algorithm that allows carrying out sub-metric positioning using precise carrier phase measurements for a dynamic receiver. During the motion, the measured carried phases are changing according...
The continuity of the positioning service, in all potential environments, and specifically from outdoors to indoors, is a fundamental aspect when one wants to increase the use of location-based services. Many techniques have so far been investigated, ranging from inertial systems to the latest light fidelity approaches. Besides these physical means, an aspect which is almost as important is the associated...
Indoor positioning seems to be one of the most challenging positioning problems. Many techniques have been proposed for many years now, ranging from inertial sensors to light-based systems. So far, our approaches have been based on a very simple basis: since GNSS (Global Navigation Satellite System) receivers are widely available on mobile terminals, why not use them. Thus, the main principles are...
