摘要
The control of the frequency spectrum state under operating conditions of the satellite networks that include plenty of satellite earth stations is one of the main functions of ground segment of space communication systems. In this case, the control system of the satellite network must measure the parameters of separate network segments or separate earth station if it is necessary. The necessity for selective measurements is relevant in the following cases: the power level, noise level or spurious radiation level of any earth station is significantly higher than the nominal one. The overview of some existing monitoring systems that makes automatic control of the frequency spectrum is presented. The analysis of the problem arisen during the functioning of satellite TDMA networks that involve plenty of earth stations is presented. Based on the analysis, it was concluded that the existing control systems of the satellite networks do not allow measuring high frequency parameters of separate earth stations under TDMA technology. The analysis of the problem of measuring the channels parameters of satellite network functioned by using the TDMA technology is presented. The differences between computations of channel power under "single channel per curie?' technology and the TDMA technology are presented. The authors proposed an automatic control system of high-frequency (HF) parameters of satellite signals, functioning by using the time-division multiple access technology. The block diagram of this system and description of its operation are presented. The conditions for implementing this automatic control system are defined. The time chart and its characteristics were calculated during measurements executing by this automatic control system. The method of match making between the received signals through the satellite segment and the identifiers of earth stations of the satellite network is presented.
