Referring to FIG. 1, the satellite repeater monitoring apparatus 100 includes an information receiver 102, an information analyzer 104, and an output unit 106.

The information receiver 102 may receive telemetry information about the satellite repeater. Telemetry information includes information about the state of the satellite repeater and whether the satellite repeater is reliably executing the telecommand transmitted from the ground. For example, the telemetry information may include the temperature of the satellite, the voltage and current of the power supply, the transmission power, the attitude of the satellite, the pressure remaining in the jet fuel for attitude control, and the like.

In addition, the information receiver 102 may receive current space weather information. Cosmic weather information such as solar, cryogenic, ultra-vacuum, cosmic ray, radiation, weightlessness, solar wind, and the like can be received to grasp changes in the space environment. Changes in the space environment, such as solar storms, excessive input of high energy proton particles by solar flares, and the like can affect the state of the satellite. In addition, the information receiver 102 may further receive not only current space weather information, but also space weather alert information that is a result of predicting future space weather information.

The information analyzer 104 may analyze telemetry information that is affected by the current space weather information among the received real-time telemetry information. A general satellite repeater monitoring apparatus can analyze the telemetry information of a satellite repeater at any point of time by using a minimum value, a maximum value, an average value, a distribution chart, and the like, to analyze the tendency of the telemetry. On the other hand, the information analysis unit 104 of the satellite repeater monitoring apparatus according to an embodiment of the present invention may analyze the telemetry information, space weather information and space weather alert information received in real time. In other words, after grasping the change in the space environment by using the space weather information and the space weather warning information, the change in the telemetry information according to the change in the space environment may be analyzed. The information analyzing unit 104 preliminarily changes the specific space environment based on analyzing specific telemetry information when the change in the specific space environment affects specific telemetry information, that is, the function of a specific part of the satellite. You can decide. In addition, a minimum amount of change in a specific space environment affecting specific telemetry information may be previously determined as a threshold. The information analyzing unit 104 may determine the specific telemetry information based on the specific space weather information or the like when the specific space weather information or the specific space weather warning information that affects the specific telemetry information exceeds the threshold. Statistical or time varying characteristics can be analyzed.

In addition, the output unit 106 may output a result of parsing the received real-time telemetry information and a result of processing the space weather information and the space weather warning information using a specific weight function on a screen as a graph or a number. The satellite operator may check the output result and transmit the corresponding satellite command to the satellite repeater. By outputting not only the analyzed telemetry information but also the received telemetry information and the received space weather information, the output unit 106 can grasp the relationship between the telemetry information and the space weather information.

Although not shown in FIG. 1, the satellite repeater monitoring apparatus 100 may further include a reception period adjusting unit. In general, the information receiver 102 may receive real-time telemetry information at regular intervals. However, as a result of analysis by the information analysis unit 104 of the present invention, if the specific space weather information and the like that affect the specific telemetry information exceeds the threshold, the reception period adjusting unit receives the reception period of the specific telemetry information Can be adjusted. For example, the reception period adjuster shortens the reception period so that satellite operators receive telemetry information about parts of the satellite that may be contaminated by changes in the space environment. To monitor and control the status of the part. Subsequently, at a time point when specific space weather information or the like is analyzed below the threshold, the reception period adjusting unit may generally adjust the reception period again. That is, the reception period adjusting unit may prevent the overload of the satellite repeater monitoring apparatus 100 by adjusting the reception period longer than in an emergency when space weather information is normal.

When the specific space weather affects specific telemetry information, the telemetry information analyzer 312 may predetermine the specific space weather as a criterion for analyzing the specific telemetry information. In addition, the minimum amount of change in a particular space weather that affects specific telemetry information may be previously determined as a threshold. The telemetry information analysis unit 312 is a statistical or time-variable of the specific telemetry information on the basis of the specific space weather information when the amount of change in the specific space weather affecting the specific telemetry information exceeds the threshold.
