Session: Network and constellation: status and evolution

Presentation type: Type Oral

Co-locations with other space geodesy techniques have always been a major objective throughout the deployment and evolution of the DORIS network. Co-locations of DORIS with tide gauges became scientifically interesting with the launch of TOPEX/Poseidon in 1992, the first satellite using DORIS for oceanography purposes.

After an introduction about site surveys and co-locations, this presentation is divided into two parts to make a separate assessment of co-locations with space geodetic techniques and tide gauges.

We give a current status and examine the distribution and configuration of co-location sites including DORIS since the beginning of the network deployment 30 years ago with a detailed analysis of the tie vectors uncertainties through the ITRS realizations.

We illustrate by few examples the respective contributions of these co-locations to the ITRF determination and the sea level monitoring.

Finally, we provide some definitions and specifications for a good DORIS co-location site and give, in the context of current objectives, the prospects for the DORIS network as regards co-locations.
