Description

TECHNICAL FIELD [0001] The present invention relates to a method and a system for a satellite,

The present invention relates to a method and system for planning a mission of a satellite, and more particularly, to a method and a system for a mission of a satellite capable of performing a mission assignment of a satellite based on automation.

In general, a satellite is an artificial month that is fired from the Earth and orbits the earth, and can be used for scientific observation studies, industrial activities such as gathering necessary information for safety, including military, or using space. Monitoring and control on the ground to enable orbital satellites to perform their intended mission is called ground control, and the integration of various devices for ground control is called a control system.

The satellite ground control system includes a TTC subsystem (Telemetry, Tracking and Command Subsystem) that uses an antenna to track satellites and transmit and receive radio waves to communicate with the satellite and the control system. There is a Flight Dynamics Subsystem that performs the determination and prediction of the orbit of the satellite.

On the other hand, it is the mission plan to plan the most effective utilization of the resources available to the satellites to perform the intended mission effectively. This function is performed by the Mission Planning Subsystem. In order to enable the satellite to operate according to the mission plan, the command sequence must be sent sequentially on the ground, which can be recognized by the satellite. Such a command scheme is performed by the Satellite Operations Subsystem. Thus, it is the satellite control system that several subsystems consist of respective computers and associated devices and operate in an interconnected manner.

Among them, the mission planning sub-system collects the information to be transmitted to the satellite event, the satellite start plan and the satellite from the photographing request and flight dynamics subsystem created by the user of the satellite payload user organization for the mission planning, To plan the mission of the satellite and deliver the planned results to the user agency and the satellite command generation system.

However, this task planning task is a manual operation method requiring both a user who requests shooting of the satellite payload and an operator who creates the entire mission plan in response to the request, and performs mission planning on weekends and holidays when the operator does not work It is not easy to change the shooting plan suddenly to observe the weather phenomenon such as typhoon. In particular, there is a problem in that assignment of the manpower is restricted because only the operator having the expert knowledge in the mission plan can operate the system.

If there is an error in the verification according to the manual operation, there is a problem that it can have a serious effect on work such as cost loss and real-time weather observation.

1 is a configuration diagram of a mission planing system of a satellite according to an embodiment of the present invention.
2 is a flowchart illustrating a mission planning process of a satellite according to an embodiment of the present invention.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily carry out the present invention.

FIG. 1 shows a configuration diagram of a mission planing system for a satellite according to an embodiment of the present invention.

As shown in FIG. 1, the mission planning system 1 of the satellite includes an MPS server 100 and an MPS client 200.

The mission planning system (1) of the satellite is designed to be suitable for the mission planning of sensors mounted on satellites such as the characteristics of satellites, weather observation sensors, marine and environmental monitoring sensors, It is a hybrid automatic process that can be used in combination with manual and automatic operation, since it must operate 24 hours a day, 365 days a week.

To this end, the mission planning system (1) of the satellite sets the mode according to the task required for the mission planning of the satellite and sets the mode (automatic mode (automatic instant mode, automatic reservation mode), automatic and manual blending mode, The log message or the alarm for the execution condition, the execution method, the execution time and the result of the detailed operation constituting the detailed operation can be made to operate differently.

In this way, the mission plan of the satellite is composed of complicated tasks considering various input / output, mutual interface with external organizations, and sensor operating conditions. Therefore, it is possible to group the tasks into processes and set the mode according to the operation method It can organize the whole processes that should be performed automatically by grouping the detailed tasks, and set the operation method for each task to support various operating methods and perform a flexible (correctable) automatic execution process.

Here, the automatic quick mode is a mode in which the detailed operation is automatically performed when the input conditions for performing the respective steps are automatically set, and can be utilized when the immediate operation such as emergency operation is required.

The automatic reservation mode is a mode that is performed automatically and is performed immediately after the scheduled time, even if the input conditions for performing each step are satisfied. It can be used when checking and verifying according to business hours schedule. In this way, the automatic reservation mode is an operating process that combines the advantages of automatic mode and the advantages of manual mode. It automatically processes all the time consuming and routine tasks, and for tasks requiring operator confirmation, But if the operator's confirmation is not made by a certain time, if there is no error in the automatic verification function, the operation can be performed automatically to the next operation. That is, even if there is no operator intervention, it is possible to perform the tasks to be performed until a certain time, thereby producing the result of the mission plan.

The automatic and manual blending mode is a process that mixes the automatic mode and the manual mode. It can set the manual operation for a specific operation and, if set, wait until the operator operation is input. The automatic and manual blending modes are time-consuming and process all routines automatically, and allow operators to perform manual operations on operations that require confirmation by the operator. In addition, the automatic and manual mixing mode can be used for a certain operation period (LEOP / IOT period after satellite launch) or periodic sensor verification period (sensor calibration time) in which operator's confirmation is required.

Manual reservation mode is basically a process that is performed manually or in a trivial manner so that it can be performed automatically. Manual scheduling mode allows operators to manually perform key tasks (eg, sensor job planning, conflict resolution and reconciliation), and delivery to other external organizations and interfacing with other software are performed automatically based on the scheduled time Mode. As described above, the manual reservation mode is a mode that utilizes the convenience of the automatic mode. It is a mode in which only trivial tasks or routine tasks are partially automated based on the manual operation at the time of initial operation and verification after the satellite launch And can be used when processing.

In addition, various modes can be set (added, deleted, or modified) according to the operation method, thereby creating an operation process based on the automatic execution.

The MPS server 100 may receive FDS data from the Flight Dynamics Subsystem (FDS) 30, including satellite events, satellite launch plans, and ephemeris. The FDS data may include Eclipse information, solar intrusion information, radiation correction observation information of the payload, payload electronic calibration information, and the like.

More specifically, when the preset mode is the automatic mode, the MPS server 100, which is the main operating agency, can check whether the data transmission event is received from the FDS 30 or periodically check whether the FDS data is inputted at a predetermined position. The MPS server 100 may automatically load the FDS data and perform verification of the details of the FDS data when the data transfer event is received or the FDS data is input at a predetermined position. The MPS server 100 verifies the format of each file or verifies the range of the normal value of each data item. When the verification operation is completed, the verification result of the FDS data is transmitted to the MPS server 100 ), And a start message indicating that the data transferred from the FDS 30 is transmitted and is ready to start the mission planning can be generated and announced in an audio or video format.

The task is collectively referred to as a task that the payload unit must perform in order to acquire a desired image by the user organization (MPS client 200). The payload scheme selects the type, order, and number of images in the time interval range It means work.

The MPS client 200 can compare the mission plan and the event of the satellite with the start-up operation to check whether a collision occurs, and adjust the collision when it occurs to generate a mission plan. In the automatic mode, the MPS client 200 automatically adjusts the collision using the designated priority and the collision adjustment rule, and generates and outputs a log message of the adjusted content. In the manual mode, Confirmation of collision schedule, adjustment (deletion, change of start / end time, etc.), and log message about the details adjusted by the operator can be generated and output.

The MPS client 200 may output a final conflict plan to the screen and generate a message indicating that the creation of the conflict plan has been completed through an audio or video alarm.

The MPS client 200 can transmit the mission plan of the performed satellite to the MPS server 100 according to the set mode. This is a task of transmitting the result of the mission scheduling to the MPS server 100, which may mean a shooting request.

More specifically, in the automatic instant mode, the MPS client 200 immediately sends the mission plan of the satellite to the MPS server 100, and if it is in the automatic reservation mode, it can automatically transmit the mission plan of the satellite at the scheduled time . That is, the MPS client 200 can automatically transmit the FDS data to a designated place according to a predetermined transmission method (for example, FTP, e-mail, web upload). The MPS client 200 compares or checks the size of the file size, If the transmission is not successful due to a network failure or a delay due to an error, the retransmission can be automatically attempted according to the defined number of times or procedures. In the manual mode, the MPS client 200 transmits the file selected by the operator according to a transmission request of the operator, and allows the user to manually confirm whether or not the transmission is normal. At this time, the MPS client 200 can output the success or failure of the FDS data transmission through an audio or video alarm.

The MPS server 100 may perform verification of the mission plan of the received satellite. This means re-checking and verifying the content of the incoming mission plan before uploading it to the satellite.

More specifically, in the automatic mode, the MPS server 100 can check whether the content of the mission plan arrived from the outside satisfies all the specified rules and conditions, and generate a log message or an alarm for the result and output it. If all of the verification conditions are not satisfied, the MPS server 100 may automatically adjust the plan according to predetermined rules and generate and output a related message. In the manual mode, the operator can check the contents of the mission schedule and the parameter values directly to verify the mission plan of the satellite.

The MPS server 100 can generate a mission timeline using the mission plan of the verified satellite and send it to the upload performing subsystem 50 (ITOS). This is a task of creating a mission timeline that can be used as an input for satellite upload and transmitting the completed mission plan to the ITOS 50, And the result transformed into a form that can be expressed.

More specifically, when the MPS server 100 is in the automatic mode, it can generate a mission timeline, verify the generated result, and automatically transmit the generated result to the upload performing subsystem 50. In the automatic mode, In the case of the automatic reservation mode, it is possible to generate a mission timeline after waiting for a designated time to perform the transmission by generating the mission timeline immediately after receiving the satellite mission plan and performing the transmission. In the manual mode, the operator can create a mission timeline and verify the contents of the generated result and transmit it to the upload performing subsystem 50. Then, the MPS server 100 can generate and output an alarm message for generation and transmission of the mission timeline.

In this manner, the operation progress status of the MPS server 100 is displayed on the screen in real time so that the operator can monitor the operation progress status when necessary, and the results (mission timeline and mission event file) Command generation system and user organization, respectively.

Then, the MPS server 100 stores and manages the parameters related to the mission plan, and can quickly implement the mission plan that can be interrogated and interoperated with the mission schedule.
