The purpose of this series of conferences
is to discuss problems ranging from the concepts and realizations of space
and time reference systems to the scientific interpretations of precise observations
referred to these systems.
This series of conferences on the general topic of
reference systems, each one with a specific sub-title,
have been organized in Paris each year from 1988 to 1992 and alternately, since
1994, in Paris and other European cities: Warsaw in 1995, Paris in 1996, Prague
in 1997, Paris in 1998 including an "Orlov session" following the tradition
of the "Orlov conferences", Dresden in 1999 following also the tradition of
the "Lohrmann colloquia" and Paris in 2000. They have then been organized three
successive years outside of Paris: Brussels in 2001, Bucharest in 2002 and St Petersburg
in 2003 and they are coming back to Paris in 2004.
