| ABSTRACT: | |
| /AB | We have used the new gravity field model GGM01C derived from GRACE data |
| to reanalyze DORIS data from 1993.0 to 2003.2 using the Gipsy /Oasis | |
| software and a free-network approach. We have estimated the position and | |
| velocity of each DORIS station in ITRF2000. In order to test the accuracy | |
| of these results, we have compared them to the positions and velocities of | |
| 43 collocated GPS stations using local ties and covariance information. | |
| DORIS results computed using the GGM01C gravity field instead of the EGM96 | |
| gravity field show a significantly improved external agreement with GPS. | |
| Position agreement of 12-26 mm was reduced to 10-13 mm and velocity | |
| agreement of 3.3-3.7 mm/yr was reduced to 2.4-3.3 mm/yr. This can be | |
| interpreted as an external test of the accuracy of the new GGM01C gravity | |
| field. | |
