Obviously navigation is one of the most complicated issues in mobile robots. Intelligent algorithms are often used for error handling in robot navigation. This Paper deals with the problem of Inertial Measurement Unit (IMU) error handling by using Extended Kalman Filter (EKF) as an Expert Algorithms. Our focus is put on the field of mobile robot navigation in the 2D environments. The main chall...

Localization and motion control (navigation) are two major tasks for a successful mobile robot navigation. The motion controller determines the appropriate action for the robot’s actuator based on its current state in an operating environment. A robot recognizes its environment through some sensors and executes physical actions through actuation mechanisms. However, sensory information is noisy...

The ionosphere is an important component of near-Earth space that has a significant impact on communication and navigation. Furthermore, the total electron content (TEC) widely used parameter in plasma environment studies. A design digital beacon receiver system for automatically measuring TEC presented. Universal Software Radio Peripheral (USRP) hardware equipment with software-defined radio t...

Satellite transmissions have an important role in telephone communications, television broadcasting, computer communications, maritime navigation, and military command and control. Moreover, in many situations they may be the only possible communication set-up. Recent trends in telecommunications indicate that four major growth market/service areas are: messaging and navigation services (wirele...

Maintaining constant communication between mobile entities distributed across a large geographical area is a crucial task for many commercial and military applications. For example when troops are deployed in hostile or sensor deprived environments, maintaining radio contact with a base station would increase the efficiency of coordinating the deployment, yet maintaining communications should n...

Portable wireless technology provides many benefits to modern day travelers. Over the years however, numerous reports have cited portable electronic devices (PEDs) as a possible cause of electromagnetic interference (EMI) to aircraft navigation and communication radio systems. PEDs may act as transmitters, both intentional and unintentional, and their signals may be detected by the various radi...

ESA and NASA have a cooperation related to the demonstration of the value for space users of using dual GNSS system (GPS plus Galileo) receiver compared to use of a single GNSS system (GPS) receiver. For this demonstration a joint ESA-NASA activity has been initiated, based on the use of NASA’s SCAN Testbed on-board the International Space Station (ISS). The joint project has several objectives...

Currently, the Global Positioning System (GPS) is undergoing stunning changes that will enhance both military and civil capabilities. We say that GPS is being modernized. In fact, this modernization is a fabric of change that includes three elements. It includes integrity machines, which are monitors that provide error bounds to safety-critical users in real time. It also includes a family of t...
