Considerations on the observation of GNSS-signals with the VLBI2010 system
Konferensbidrag (offentliggjort, men ej förlagsutgivet), 2009

One interesting aspect for the de- velopment of the VLBI2010 system would be to have the possibility to observe Global Nav- igation Satellite System (GNSS) signals. This might allow to improve the integration and com- bination of these techniques, which is an im- portant aspect for the Global Geodetic Observ- ing System (GGOS) of the International Asso- ciation for Geodesy (IAG). We present calcula- tions for different GNSS systems and VLBI radio telescope sensitivities to assess the expected sig- nal strength. We present L-band observations of GNSS signals and attempts to receive GNSS sig- nals with present day S-band systems. Finally, we give a rough estimation on the expected pre- cision of the VLBI delays and the positions of the GNSS satellites.
