Automated satellite interference mitigation

摘要

An automated process to periodically check and ensure that earth terminal settings provide compliant EIRPSD. For example, one embodiment of the present invention provides an apparatus which queries the modem for its transmit symbol rate and the Block Up-Converter (BUC) for its RF output power. Using these two values and preprogrammed values for connection loss between the BUC and antenna, the current input power spectral density being transferred to the antenna is computed by the apparatus and compared to the preprogrammed regulatory limit for the specific antenna. If the limit is being exceeded, the apparatus sets BUC attenuation to compensate for the excess.

1. A method for setting operating parameters of an earth terminal, the earth terminal including a processing unit, a modem, and a block up-converter (BUC), the method comprising the steps of:
obtaining a transit symbol rate (TSR) of the modem; obtaining an RF output power (Po) of the BUC; using the processing unit,
calculating a value of a BUC output power spectral density (PSDo) according to PSDo=10*Log(Po/TSR), andcomparing the PSDo value with a predetermined value of a power spectral density limit (PSDL) to determine an excess value (D) by which PSDo exceeds PSDL; and if D>0, changing an attenuation setting of the BUC by D, thereby compensating for the excess.
