4M orbit determination after data processing

4M orbit determination after data processing.

After processing of all the received data, we finally have a very nice parameter set. It has been obtained by the solution of a least cost error function using the dF data that were transmitted by all OM’s that participated and our own received data.

The following graph shows the fit of received data (Doppler) and the corresponding Two Lines Elements.

Many thanks to Jean-Baptiste for this wonderful work.
