goGPS is a free and open source navigation software that processes raw GPS data in differential mode with respect to a network of permanent stations and in stand-alone mode. It can use both code (C/A, P) and phase (L1, L2) measurements obtained from geodetic or low cost devices. goGPS applies a Kalman filter directly on the GPS observations, estimating a position at every epoch also by exploiting a dynamic model (constant velocity or acceleration). The positioning is optionally supported by route constraints (e.g. a railway). Moreover, it is possible to introduce into the filter an additional observation extracted from a digital terrain model (DTM) in order to increase accuracy in the vertical direction. In this work the ionospheric and pseudorange corrections provided by EGNOS have been introduced in the stand-alone module of the software. An analysis of the improvements reached in the presence of EGNOS have been studied from data acquired by low cost receiver u-blox AEK-4T.

Abstract

goGPS is a free and open source navigation software that processes raw GPS data in differential mode with respect to a network of permanent stations and in stand-alone mode. It can use both code (C/A, P) and phase (L1, L2) measurements obtained from geodetic or low cost devices. goGPS applies a Kalman filter directly on the GPS observations, estimating a position at every epoch also by exploiting a dynamic model (constant velocity or acceleration). The positioning is optionally supported by route constraints (e.g. a railway). Moreover, it is possible to introduce into the filter an additional observation extracted from a digital terrain model (DTM) in order to increase accuracy in the vertical direction. In this work the ionospheric and pseudorange corrections provided by EGNOS have been introduced in the stand-alone module of the software. An analysis of the improvements reached in the presence of EGNOS have been studied from data acquired by low cost receiver u-blox AEK-4T.
