The present study consists in studying the mean orbital motion of the CHAMP satellite, through a single long arc on a period of time of 200 days in 2001. We actually investigate the sensibility of its mean motion to its accelerometric data, as measur

The space traffic management is becoming more and more complex with the growing number of maneuvering satellites in particular in low Earth Orbit (LEO) due to the race for large constellations of communication satellites. One of the major challenges

In the last years significant understandings in the knowledge of the dynamics of the MEO satellites were achieved. Much work was done in the analysis of viable disposal strategies and technologies for the spacecraft belonging to the Global Navigation

We present the results of an extensive numerical exploration performed on the eccentricity growth in MEO associated with two possible end-of-life disposal strategies for GNSS satellites. The study calls attention to the existence of values of initial

International audience; Tahiti is a unique geodetic site located in the south Pacific Ocean where few observatories exist nearby. The American mobile station MOBLAS-8 was installed in Tahiti in 1998, and GPS and DORIS systems were also deployed in it
