Embodiment Construction
[0028] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0029] like figure 1 As shown, the simplified block diagram of the transparent transponder jumping beam load provided by the present invention is as follows:
[0030] The gateway station generates the forward service signal time slot required for each beam, and sends it to the star through the feeder uplink, and the forward link transponder on the star receives the service signal and performs regeneration demodulation on the service signal According to the corresponding beam information contained in the service information, a beam control signal is generated to the on-board hopping beam controller for beam switching, and at the same time, the forward link transponder re-modulates the service signal to generate a service signal corresponding to the beam.
[0031] like figure 2 As shown, a kind of beam-hopping synchronization method for tran...
