Performance Modeling for Automatic DAMA Control

ViaSat, Inc. is pleased to present our comprehensive and creative methodology for modeling the performance of Automatic DAMA control systems. Our approach provides an objective, quantitative, unambiguous, and systematic envrionment for defining what "performance" really means to fleet satcom users. We then who how to use this environment to compare the performance of candidate DAMA controller strategies. Our performance modeling environment takes into account all of the aspects of automatic DAMA control, including; the constrints due to DAMA terminals and technical interface standard,s selection of observable statistics to measure, definition of system stochastic input paramters, and computer software that ties it all together. The proposed Phase I work includes analysis and simulation to quantify system performance under a variety of statellite configuration, terminal, operational, and traffic models. It also includes actual real-time simulation of candidate automatic DAMA control strategies that prove the value of the performance model. A successful Phase I feasibility program leads directly to a UHF on-the-air Phase Ii proof-of-concpet demonstration, including measurements to verify performance predicted in Phase I. The high pay-off Phase II program is tailored for a Phase III opportunity to feed the pwoerful netowrk controller into mainstream UHF satcom programs.
