A study on satellite network configuration control employing transmission power control

A method of satellite network configuration control is proposed in which th e transmitted power of multiple earth stations is controlled, and received power-differences are established among them to generate the capture effect . The performance of the proposed method is also evaluated. First, the outl ines of the system configuration used in experiments are presented and the fabricated satellite circuit monitoring/control system and the concepts of inbound and outbound satellite communication network control are described. Next, experimental results on the capture effect are presented and the pos sibility of its uses in satellite circuits is considered. Further, the meth od of station switchover required in application of the capture effect appl ied to satellite communication network control is also proposed and its cap abilities are assessed. Finally, the concept of so-called "stealthy transmi ssion" is introduced as a new application of the capture effect. The satell ite circuit switching required in sending the stealthy transmission is desc ribed and its possibility is verified. (C) 2000 Scripts Technica, Electron Comm Jpn Pt 1, 83(7): 103-112, 2000
