Abstract

Provided is a method of comparing satellite attitude control performances, the method including generating, by a controller, a satellite task execution command, receiving, by an input and output (I/O) unit, a result of a simulation performed on a satellite attitude control by a satellite attitude control simulator based on the satellite task execution command, and transmitting, by the I/O unit, the satellite task execution command to a satellite based on the result of the simulation.

First claim

What is claimed is:

1. A method of comparing satellite attitude control performances, the method comprising:
generating, by a controller, a satellite task execution command;
receiving, by an input and output (I/O) unit, a result of a simulation performed on a satellite attitude control by a satellite attitude control simulator based on the satellite task execution command; and
transmitting, by the I/O unit, the satellite task execution command to a satellite, responsive to a comparison of the result of the simulation with a predetermined parameter, being within a predetermined range.

2. The method of claim 1 , wherein the satellite task execution command includes an input for each of a command and the satellite attitude control simulator.

3. The method of claim 1 , further comprising:
receiving, by the I/O unit, a result obtained by applying the satellite task execution command to the satellite; and
comparing, by the processor, the received result to the result of the simulation, to feedback update the satellite task execution command.

4. The method of claim 1 , wherein the transmitting includes changing, by the processor, the satellite task execution command when the result of the simulation is beyond a predetermined range.

5. The method of claim 4 , further comprising:
transmitting, by the I/O unit, the changed satellite task execution command to the satellite attitude control simulator.

6. The method of claim 1 , wherein the satellite task execution command is associated with at least one of an execution start time and an execution end time, initial attitude and position, an execution angle, or a thruster operating time.

7. An apparatus for comparing satellite attitude control performances, the apparatus comprising:
a processor configured to generate a satellite task execution command; and
an input and output (I/O) unit configured to receive a result of a simulation performed on a satellite attitude control by a satellite attitude control simulator based on the satellite task execution command,
wherein the I/O unit is configured to transmit the satellite task execution command to a satellite, responsive to a comparison of the result of the simulation with a predetermined parameter, being within a predetermined range.

8. The apparatus of claim 7 , wherein the I/O unit is configured to receive a result obtained by applying the satellite task execution command to the satellite, and the processor is configured to compare the received result to the result of the simulation, to feedback update the satellite task execution command.

9. The apparatus of claim 7 , wherein the processor is configured to change the satellite task execution command when the result of the simulation is beyond a predetermined range.

10. The apparatus of claim 9 , wherein the I/O unit is configured to transmit the changed satellite task execution command to the satellite attitude control simulator.

11. The apparatus of claim 7 , wherein the satellite task execution command is associated with at least one of an execution start time and an execution end time, initial attitude and position, an execution angle, or a thruster operating time.

12. A non-transitory computer-readable medium storing program instructions for controlling a processor to perform a method of comparing satellite attitude control performances, the method comprising:
generating, by a controller, a satellite task execution command;
receiving, by an input and output (I/O) unit, a result of a simulation performed on a satellite attitude control by a satellite attitude control simulator based on the satellite task execution command; and
transmitting, by the I/O unit, the satellite task execution command to a satellite, responsive to a comparison of the result of the simulation with a predetermined parameter, being within a predetermined range.
