To demonstrate the feasibility of beam hopping techniques by implementing the key technologies both at payload and ground segmentas well the required interactions, taking into account the results of system studies on the beam hopping in reduction of the on- boardDC power consumption as well as reduction in the mass by sharing one tube to serve several beams. Targeted Improvements: Beamhopping can match offered capacity with traffic demand. Compared to uniform power and bandwidth assignment per user beam, the beam hopping provides 50% reduction of DC power consumption. Using the beam hopping, one power amplifier can serve up to 8 beams providing significant saving in required mass particularly for multi-beam systems with user link in Ka band with a large number of beams.
