Accurate localization of medical instruments with respect to patient anatomy is an integral part of computer-assisted interventions. Electromagnetic tracking is the primary choice, particularly for minimally invasive ...

Unmanned ground mobile robots are land-based robots which do not have a human passenger on board. They can be either autonomous, or controlled via telecommunication. For navigational purposes, GPS is often used. However, ...

Autonomous vehicles’ positioning and navigation (POS/NAV) systems provide drivers with route guidance information relying mostly on the Global Navigation Satellite Systems (GNSS). The GNSS–based POS/NAV systems suffer from ...

Where am I? This question continues to be one of the fundamental challenges posed in robotics research. The ability of a robot to localize itself and map its environment has proven to be a difficult and rich research ...

Land vehicle navigation is primarily dependent upon the Global Positioning System (GPS) which provides accurate navigation in open sky. However, in urban and rural canyons GPS accuracy degrades considerably. To help GPS ...

Despite the major advances in signal processing methods used nowadays, GPS receivers still face substantial challenges, such as multipath, which remains a dominant source of ranging error. The presence of GPS multipath ...
