GPS Stochastic Modelling: Signal Quality Measures and ARMA Processes

Global Navigation Satellite Systems (GNSS), such as GPS, have become an efficient, reliable and standard tool for a wide range of applications. However, when processing GNSS data, the shastic model characterising the precision of observations and the correlations between them is usually simplified and incomplete, leading to overly optimistic accuracy estimates.

This work extends the shastic model using signal-to-noise ratio (SNR) measurements and time series analysis of observation residu...
