Abstract

The present invention relates to an apparatus and a method for simulating a satellite mission operating state. The apparatus, according to the present invention, comprises: a satellite operation procedure rule definition unit for registering a satellite operation procedure rule which defines a satellite operation procedure keyword and attribute corresponding to a satellite's state of performing a mission of interest; a satellite operation procedure processing unit for receiving a satellite operation procedure which includes a series of operation procedures prepared for the satellite to perform the mission, and extracting, from the received satellite operation procedure, a keyword and attribute value corresponding to the keyword and attribute included in the registered satellite operation procedure rule a mission list storage unit for storing a list of mission performance actions arranged in the order of execution time, wherein the mission performance actions correspond to the extracted keyword and attribute value; an orbit data storage unit for storing orbit data of the satellite; a time management unit for providing a current time; and a control unit for confirming an orbit and the mission performance action corresponding to the current time from the orbit data of the satellite and the mission list, and causing the satellite's state of performing the mission of interest to be visually displayed.

First claim

What is claimed is:

1. A method for simulating a satellite mission operating state, comprising:
registering a satellite operation procedure rule which defines a satellite operation procedure keyword and attribute corresponding to a satellite's state of performing a mission of interest;
receiving a satellite operation procedure which includes a series of operation procedures prepared for the satellite to perform the mission;
extracting, from the received satellite operation procedure, a keyword and attribute value corresponding to the keyword and attribute included in the registered satellite operation procedure rule;
storing a list of mission performance actions arranged in an order of execution time, wherein the mission performance actions correspond to the extracted keyword and attribute value; and
confirming an orbit and content of an action of interest corresponding to a current time from orbit data of the satellite and the list of mission performance actions, and causing the satellite's state of performing a mission of interest to be visually displayed,
wherein the causing the satellite's state of performing a mission of interest to be visually displayed includes displaying, in real time, at least one of communication, attitude slewing, data acquisition or data transmission.

2. The method according to claim 1 , further comprising:
registering a satellite command rule which defines a satellite command keyword and attribute corresponding to the satellite's state of performing the mission of interest; and
receiving a command corresponding to mission performance of the satellite, and extracting, from the received command, a keyword and attribute value corresponding to the keyword and attribute included in the registered satellite command rule.

3. The method according to claim 2 , wherein the satellite operation procedure keyword is an ASCII code, and the satellite command keyword is an HEXA code.

4. A non-transitory computer-readable recording medium storing a program for executing the method of claim 1 on a computer.

5. A non-transitory computer-readable recording medium storing a program for executing the method of claim 2 on a computer.

6. The non-transitory computer-readable recording medium according to claim 5 , wherein the satellite operation procedure keyword is an ASCII code, and the satellite command keyword is an HEXA code.
