Since Monday June 27th 5:00 am GMT, AMS02 is controlled from the newly built POCC (Payload Operation Control Center) at CERN (Prevessin Side). 24/7 shifts are organized to monitor AMS-02 operation and the continuous flow of data to ground.

The transition started on Wenesday June 22nd, and took place smoothly, initially with two shifts overlapping between JSC and CERN.  The average experiment downlink rate is about 10 Mbps, with peaks at higher rate  to cope with the periods when the downlink channel is not available.

On June 26th the POCC has been inaugurated in the presence of two exceptional guests, Charlie Bolden, NASA Administrator and Rolf Heuer, CERN DG.

Through the summer AMS-02 will collect several billions of Cosmic Rays events, which, after reception at CERN, will be deframed and reconstructed at the CERN Science Operation Centers, before being sent to the various regional centers for calibration and analysis.
