| Abstract: | The linearization of pseudo-range observation model of receiver autonomous integrity monitoring(RAIM) algorithm based on least squares residual(LSR) may result in truncation error.Taking the influence of environmental noise on the data matrix and the measurements into consideration,the RAIM solution model is presented based on the total least squares(TLS) estimation criterion,which can promote the accuracy of residuals and the reliability of data.Consequently the precision and reliability of positioning sol... |
