GNSS networks for real time compute differential corrections using undifferenced equations to model observations' biases. The main goal of the present work is to analyse the contribution of the correlations in a network solution, due to some common parameters such as ephemeris or satellites' clocks. Some network simulations have been carried out considering undifferenced equations with different number of stations. In addition we investigate the opportunity to consider a multi-station with three joint antennas, instead of a single permanent station, to quantify the contribution that the increased correlations could provide in the estimation of the GNSS observations' biases and in the network design.

Abstract

GNSS networks for real time compute differential corrections using undifferenced equations to model observations' biases. The main goal of the present work is to analyse the contribution of the correlations in a network solution, due to some common parameters such as ephemeris or satellites' clocks. Some network simulations have been carried out considering undifferenced equations with different number of stations. In addition we investigate the opportunity to consider a multi-station with three joint antennas, instead of a single permanent station, to quantify the contribution that the increased correlations could provide in the estimation of the GNSS observations' biases and in the network design. The obtained results are compared with a solution computed with a Kalman filter, ad-hoc implemented to process a real data-set.
