The main space-time characteristics of inhomogeneities arising in ionospheric plasma are given. models the radio channel shown taking into account large, medium and small scales for navigation satellite systems. results measurements data processing these systems presented. It is that on propagation path can lead to strong signal fading. According depth fading, scintillation indices determined, ...

A survey of the information sources and information fusion technologies used in the current in-car navigation systems is presented. The pros and cons of the four commonly used information sources GNSS/RF-based positioning, vehicle motion sensors, vehicle models and map information are described. Common filters to combine the information from the various sources are discussed. A prediction of po...

In a context of the evolution of localization based on the technological progress and the implementation of GNSS such as GPS or the European Galileo project to used in outdoor environment allowing accuracy of a few meters, but for an indoor environment, the signal is deteriorated due to the obstacles, so other techniques are used. This paper provides an overview of the indoor localization techn...

current research interests are location-based security services, signal authentication and fuzzy extractors. Christof Paar is a Professor in Electrical and Computer Engineering at the University of Bochum where he heads the chair for Embedded Security. His research interest includes efficient software and hardware implementations of cryptographic algorithms, sidechannel attacks, cryptanalytical...

in this study, the problem of navigation in dynamic and unknown environment is investigated and a navigation method based on force field approach is suggested. it is assumed that the robot performs navigation in unknown environment and builds the map through slam procedure. since the moving objects' location and properties are unknown, they are identified and tracked by kalman filter. kalm...

This book [1] was written at an important point in the development of applications of electromagnetic (radio) waves to communications, navigation, and remote sensing. Such applications require accurate propagation predictions for a variety of path conditions, and this book provides the theoretical basis for such predictions. The book is based on fundamental research in electromagnetic wave prop...

background: short golden time is important to save the injured in earthquake and to start search and rescue (sar) operation as soon as possible in affected regions. this study evaluated application of geographic information system (gis) for sar operation in rigan town, kerman province, which was hit by an earthquake of 6.3 richter scale on december 12, 2010 at 22:12. materials and methods: a gi...

The navigation by the stellar refraction is important for a LEO (Low-Earth-Orbit) satellite, especially in GNSS (Global Navigation Satellite System)-denied environment, since it totally autonomous. However, biggest barrier to accurate lies stratospheric density. Therefore, retrieval of density star occultation proposed this paper acquire globally with high accuracy. Compared GPS Positioning Sys...

Abstract In the search for space producing renewable energy, possible negative effects of solar parks and wind farms along inland waterways can easily be overseen. This paper provides an exploratory description navigation like blinding helmsmen, disturbance radio communication exaggeration vessel’s radar images concludes with a chapter on mitigating measures.
