This report summarizes the activities of the Bordeaux Observatory Analysis Center during the year 2005. On the analysis side, we completed processing of seven years of NEOS-A/IVS-R4 data (1999-2005) and three years of IVS-R1 data (2003-2005) with the MODEST software. Additionally, we have been involved in testing the VLBI model of the GINS software for multi-technique combination at the raw data level. On the research side, our major achievements include the completion of observing for our ICRF densification project in the northern sky, the study of source structure index temporal variability--which led to the identification of 242 ICRF sources with potentially high astrometric quality--and a newly-developed activity aimed at monitoring the structure of the ICRF sources based on the RDV data. Plans for the year 2006 follow the same analysis and research lines.
