A New Variance-Covariance Matrix for Improving Positioning Accuracy in High-Speed GPS Receivers

One of the main challenges in using GPS is reducing the positioning accuracy in high-speed conditions. In this contribution, by considering the effect of spatial correlation between observations in estimating the covariances, we propose a model for determining the variance-covariance matrix (VCM) th...
