Our products

Final products generated for IDS and available at the IDS Data Centers

Caveat emptor

the products are named with two different 3-letter acronyms:

  • LCA until 2014
  • GRG from 2014

Because GRGS would like to harmonize the names of its products for the geodetic services, the original 3-letter acronym of the AC (LCA for LEGOS/CLS Analysis Center) was changed in 2014 to the 3-letter code GRG. The DORIS-derived products for the CNES/CLS contribution to the ITRF2014 are the first ones designated by the acronym GRG.
