Satellite Pseudo-range Positioning Based on Time Series Analysis

A novel real-time positioning model for single frequency receiver is proposed. The position parameters are expressed in the form of linear time series combination, and the positioning problem is converted into estimation problem of time series coefficients. Space mapping method is presented to process the measurement information of single-frequency pseudo-range. It is used to deduct clock bias, ionosphere refraction, amend residual error and other system errors. Error transfer function is improved for high precision.
