Abstract :
The ACTS LBR (Advanced Communications Technology Satellite Low Burst Rate) system is presented, concentrating on its demand assignment features. A description is given of the central role of the spaceborne baseband processor (BBP) and how traffic terminals access the BBP according to a burst time-frequency plan that operates in synchronism with the hopping beam antenna. The role of the LBR control channels in carrying out the demand assignment process is described, and models are presented for their dynamics. Simulation results are provided that quantify the dynamics of the variable demand assignment process, and that compare different algorithms for burst time plan rearrangement on the basis of relative control channel load.<>
