The aim of the research activity is to test the performance of the Galileo satellite system in terrestrial navigation applications, compared to the GNSS GPS and GLONASS systems. The kinematic positioning accuracy and the accuracies obtainable in different operating conditions have been analyzed comparing the results with those obtained using multi-constellation geodetic instrumentation in different configurations with the currently operational constellations. To verify the improvement in the performance of the Galileo satellite system related to the progress in the implementation of the system, quarterly measurement campaigns have been planned starting from December 2019, as part of the first Grant of the GRC-MS Project. For each measurement campaign, surveys were carried out in urban and extra-urban areas. The measurement campaigns were conducted using a MMS (Mobile Mapping System) vehicle of the GeoSNaV Lab, University of Trieste. For the absolute positioning, the vehicle is equipped with an Applanix Corporation® POS/LV, positioning and orientation system, integrated by inertial technology to generate stable, reliable, and repeatable positioning solutions for land-based vehicle applications. For the acquisition of Galileo GNSS, GPS and GLONASS data, a multi-constellation GNSS receiver was installed inside the vehicle, and the relative antenna fixed between the two GNSS antennas of the POS/LV system on the roof of the vehicle. Furthermore, an analysis of the performances achievable by a smartphone, capable of receiving GNSS signals, also fixed on the roof of the vehicle, was carried out.
Lo scopo dell’attività di ricerca è testare le prestazioni del sistema satellitare Galileo nelle applicazioni alla navigazione terrestre, rispetto ai sistemi GNSS GPS e GLONASS, analizzando l’accuratezza nel posizionamento cinematico e le precisioni ottenibili in diverse condizioni operative, confrontando i risultati con quelli ottenuti utilizzando strumentazione geodetica multi-costellazione in differenti configurazioni con le diverse costellazioni attualmente operative. Per verificare il miglioramento delle prestazioni del sistema satellitare Galileo legate all’avanzamento nell’implementazione del sistema, sono state pianificate a partire da dicembre 2019, nell’ambito del primo Grant del Progetto GRC-MS, delle campagne di misura con cadenza trimestrale. Per ogni campagna di misura sono stati svolti rilievi in due ambiti: ambito urbano ed ambito extraurbano. Le campagne di misura sono state condotte utilizzando il veicolo MMS (Mobile Mapping System) del GeoSNaV Lab, Università degli studi di Trieste. Per il posizionamento assoluto, il veicolo è dotato di un sistema POS/LV di Applanix Corporation®, un sistema di posizionamento e orientamento, con posizionamento GNSS integrato dalla tecnologia inerziale per generare soluzioni di posizionamento stabili, affidabili e ripetibili. Per l’acquisizione dei dati GNSS Galileo, GPS e GLONASS, a bordo del veicolo è stato installato un ricevitore GNSS multi-costellazione, e la relativa antenna fissata tra le due antenne GNSS del sistema POS/LV sul tetto del veicolo. Inoltre è stata eseguita l’analisi delle prestazioni raggiungibili da uno smartphone, capace di ricevere segnali GNSS, fissato anch’esso sul tetto del veicolo.

Abstract
The aim of the research activity is to test the performance of the Galileo satellite system in terrestrial navigation applications, compared to the GNSS GPS and GLONASS systems. The kinematic positioning accuracy and the accuracies obtainable in different operating conditions have been analyzed comparing the results with those obtained using multi-constellation geodetic instrumentation in different configurations with the currently operational constellations. To verify the improvement in the performance of the Galileo satellite system related to the progress in the implementation of the system, quarterly measurement campaigns have been planned starting from December 2019, as part of the first Grant of the GRC-MS Project. For each measurement campaign, surveys were carried out in urban and extra-urban areas. The measurement campaigns were conducted using a MMS (Mobile Mapping System) vehicle of the GeoSNaV Lab, University of Trieste. For the absolute positioning, the vehicle is equipped with an Applanix Corporation® POS/LV, positioning and orientation system, integrated by inertial technology to generate stable, reliable, and repeatable positioning solutions for land-based vehicle applications. For the acquisition of Galileo GNSS, GPS and GLONASS data, a multi-constellation GNSS receiver was installed inside the vehicle, and the relative antenna fixed between the two GNSS antennas of the POS/LV system on the roof of the vehicle.
