Abstract

Laboratory of Space Geodesy and Earth Rotation (LSGER) of the Institute of Applied Astronomy (IAA) of the Russian Academy of Sciences has been carrying on, since its creation, the computation of geodynamical products: Earth Orientation Parameters (EOP) and station coordinates (TRF) based on observations of space geodesy techniques: Very Long Baseline Interferometry (VLBI), Satellite Laser Ranging (SLR), Global Positioning System (GPS). Principal software components, used for these investigations, include: package GROSS for processing of SLR observations, package Bernese for processing of GPS observations, package OCCAM for processing of VLBI observations, software for data exchange, and software for combination of space geodesy products.
