Do not hesitate to join us for this tasty seminar which will combine theory and practice, ...

On October 15, 2020, COMET-ORB organized a seminar on the latest advances in atmospheric modeling for space mechanics issues. The prediction of the atmosphere behavior is a crucial problem for the calculation of satellite trajectory, so COMET ENV and OPS have joined for this seminar on this topic.
