Apparatus and method for communication satellite monitoring

摘要

Provided is an apparatus for monitoring a communication satellite, including: a receiver to receive at least one satellite service signal from a satellite repeater; a measurement unit to measure a frequency, a bandwidth, and a magnitude of the at least one satellite service signal; a controller to determine whether a signal transmitting station malfunctions by comparing the at least one satellite service signal with a predetermined reference value based on the measurement result; and a communication unit to inform an operator terminal about a malfunction of the signal transmitting station when the signal transmitting station is determined to malfunction.

主权项

1. A system for monitoring a communication satellite, comprising:
a signal transmitting station to transmit at least one satellite service signal; a satellite repeater to receive the at least one satellite service signal from the signal transmitting station and to transmit the at least one satellite service signal to a ground; and a communication satellite monitoring apparatus to monitor whether the signal transmitting station malfunctions by comparing the at least one satellite service signal with a predetermined reference value, wherein the communication satellite monitoring apparatus includes:
an amplifier to amplify the at least one satellite service signal that is received from an antenna;a frequency converter to convert a frequency of the amplified at least one satellite service signal;a spectrum analyzer to measure a center frequency, a bandwidth, and a magnitude of the frequency-converted at least one satellite service signal; anda signal calibrator to calibrate the at least one satellite service signal with respect to a reception path section of the antenna and the spectrum analyzer, the reception path section coupling the antenna and the spectrum analyzer.
