In this paper, a wireless localization method using ultrasonic sensors signals, Zigbees, and encoders is proposed. The proposed method avoids any interferences of signals by communicating one transmitter at a time with the help of Zigbee signals. Moreover, the wireless location information is integrated with a relative localization information by encoders using a Kalman filter for more high accurate...
Accurate positioning of objects is important for navigation applications which gives rise to many interesting and challenging mathematical problems. These problems involve the relationship between positioning accuracy and satellite geometry in accordance to the user's position. Dilution of precision is an indicator of satellite geometry for constellation of satellites used to determine a position...
