| Description: |
For the second time of their history, the IDS (International DORIS Service) and IGS (International GNSS Service) CNES/CLS Analysis Centers contributed to the realization of the ITRF (International Terrestrial Reference Frame) by submitting weekly (resp. daily) DORIS (resp. GNSS) station positions and daily EOPs (Earth Orientation Parameters) from 1993.0 (resp. 2000) to 2021.0. These DORIS and GNSS solutions were estimated with the same GINS/DYNAMO software from CNES using the ITRF2020 standards. In 2021, the CNES and CLS teams started to review the processing of the laser observations with GINS/DYNAMO with the objective to become soon an ILRS (International Laser Ranging Service) Analysis Center. Thus, since early 2023, CNES/CLS routinely estimate positions of nearly 230 stations (approximatively 60 DORIS + 150 GNSS + 21 Laser) from more than 90 geodetic satellites (9 DORIS + 80 GNSS + 5 Laser) in a coherent way.After presentation of the DORIS/GNSS/SLR GINS processing specificities, we assess the quality of our three single technique products with respect to ITRF2020. We take benefit of the collocated sites to evaluate our DORIS, GNSS and SLR solutions in terms of tie residuals (differences between the computed and surveyed ties) and to compare seasonal signals in the coordinate time series. These comparisons prepare the forthcoming developments with the mid-term goal to estimate the three single technique solutions in one single run. |
