[G05-2-01] Impact of Multi-GNSS analysis on precise geodetic applications
Today, many GNSS Permanent networks are enhanced from GPS or GPS/Glonass networks to Multi-GNSS networks supporting also the signals of the European Galileo and the Chinese BeiDou satellite system. The additional signals are beneficial to many applications. This paper focus on the impact on precise geodetic applications, such as precise coordinate determination based and daily solutions and also improvements on kinematic precise PPP solutions. Here, results from the complete processing chain are shown – from data collection to analysis.
Swisstopo, the Swiss Mapping agency enhanced its permanent network to Multi-GNSS beginning 2015. A complete MULTI-GNSS data flow based on RINEX3 is established parallel to the RINEX2 data flow mid-2015. Parallel to these developments also the field equipment was replaced after conducting a technical evaluation. All 200 reference stations were measured in 2016 by static Multi-GNSS observations of about 48 hours.
On the analysis side the scientific Bernese Software was updated enabling multi-GNSS capability and making use of the IGS MGEX products (especially the CODE-derived Multi-GNSS orbits). These developments were used to analyse the Multi-GNSS data from the field campaigns as well as to analyse the permanent networks. As first analysis centre in Europe the contribution of daily and weekly solutions to the European Permanent Network (EPN) of EUREF was switched to Multi-GNSS mid-2016.
Intersystem parameters are an important indicator of the compatibility of the coordinates and troposphere parameters between the various satellite systems. Examples will show the order of magnitude these parameters can reach and will demonstrate its impact on the final results.
On the way towards real-time, we show results of kinematic PPP solutions, addressing the possible gain using additional satellite systems.
