GNSS-mätning: idag och i framtiden

Sammanfattning: This report shows the difference between today's geodetic measurementsand the one that comes withGalileo and Beidou included. As new GNSSequipment supporting Galileo and Beidou begins to be used, what are the differences and what can be expected by users in the future?This report addresses current theory of sources of error and satellite geometry to highlight the problems associated with GNSS. Based on the sources of error and satellite geometry, the results will be presentedand discussed at the end of the report.
