Volume 12, Issue 2 , October 2019, , Pages 11-18

  Abstract: Urban canyon is categorized as hard environment for positioning of a dynamic vehicle due to low number and also bad configuration of in-view satellites. In this paper, a tuning procedure is proposed to adjust the important factors in Kalman Filter (KF) using Genetic Algorithm (GA). The authors ...  Read More

A Wavelet-based Spoofing Error Compensation Technique for Single Frequency GPS Stationary Receiver

M. R. Mosavi; A. R. Baziar; M. Moazedi

Volume 10, Issue 2 , September 2013, , Pages 9-16

  Spoofing could pose a major threat to Global Positioning System (GPS) navigation, so the GPS users have to gain an in-depth understanding of GPS spoofing. Since spoofing attack can influence position results, spoof compensation is possible through reducing position deviations. In this paper, a novel ...  Read More

Novel Radial Basis Function Neural Networks based on Probabilistic Evolutionary and Gaussian Mixture Model for Satellites Optimum Selection

M. saraf; M.R. Mosavi; K. Mohammadi

Volume 9, Issue 2 , September 2012

  In this study, two novel learning algorithms have been applied on Radial Basis Function Neural Network (RBFNN) to approximate the functions with high non-linear order. The Probabilistic Evolutionary (PE) and Gaussian Mixture Model (GMM) techniques are proposed to significantly minimize the error functions. ...  Read More

Improvement in Differential GPS Accuracy using Kalman Filter

Mohammad Reza Mosavi; Azadeh Nakhaei; Sh. Bagherinia

Volume 7, Issue 2 , September 2010, , Pages 139-150

  Global Positioning System (GPS) is proven to be an accurate positioning sensor. However, there are several sources of errors such as ionosphere and troposphere effects, satellite time errors, errors of orbit data, receivers errors, and errors resulting from multi-path effect which reduce the accuracy ...  Read More
