Description

TECHNICAL FIELD [0001] The present invention relates to a weather-satellite image processing apparatus and system,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a satellite image processing apparatus and a satellite image processing method using the same, and more particularly, to a system and method for integrating and operating a plurality of ground stations performing individual functions such as satellite data processing . To this end, a satellite image processing system capable of implementing functions commonly provided to a plurality of ground stations, providing a standardized interface, and using a standardized data format, enables a plurality of ground stations to access satellite data according to the same mechanism .

FIG. 1A is a diagram illustrating a conventional satellite image processing system.

The satellite image processing system has basic functions such as receiving, processing, analyzing, storing, and distributing satellite data. The conventional satellite image processing system differs from an operating system, a development language, a communication protocol, a satellite data format, a system setting method, and an interface of a plurality of ground stations that perform individual functions and operates depending on an operating system and a hardware platform of each system . That is, an individual ground station performs functions for a specific purpose (e.g., receiving, processing, analyzing, storing, and distributing satellite data), and is capable of operating in various OS environments (e.g., Linux CentOS, Linux RedHat, and Windows (Eg, Script, Java, Flex, Python C, and C ++), and when each ground station is interworking, there is a problem that the ground station transmits and receives satellite data over a separate channel have. Therefore, it is necessary to integrate the interface, data format, and management system of each ground station, and ensure the transparency of the position of each ground station, thereby solving the problem of dependency between the systems.

In the conventional phase image processing system, the satellite data to be processed by each of the plurality of ground stations is different from each other, so that data having different data formats may be generated even when the same data is used. Therefore, when collecting satellite data processed by other ground stations, compatibility problems due to different data formats may arise. In addition, since the repositories of satellite data such as databases and storage are operated separately, each ground station must have access to an individual repository to store or query satellite data. In this case, there is a problem that a plurality of ground stations have difficulty in utilizing satellite data stored in different data formats, and operate depending on a database or storage when an interface or channel for accessing the storage is different.

1B is a diagram illustrating a communication protocol of a conventional satellite image processing system.

Referring to FIG. 1B, in a conventional satellite image processing system, a communication protocol is specialized for each ground station such as a shared directory, a socket, and an FTP. In this case, when each ground station approaches another ground station, each ground station has a problem depending on the communication protocol. Therefore, there is a need to build a satellite image processing system in which a unified communication protocol is provided.

1C is a diagram illustrating an interface of a conventional gaseous environment satellite image processing system.

Referring to FIG. 1C, in a conventional satellite image processing system, interfaces are specialized for a plurality of ground stations that perform individual functions, and access between the ground stations is complicated. In such a case, the ground station may directly allow user access individually, and control of user access may not be integrated, resulting in a problem of security. Therefore, it is necessary to integrate interfaces providing the same function to a plurality of ground stations, and to provide simple access between each ground station.

Conventionally, interfaces and data paths for accessing satellite data by a plurality of ground stations are specialized for each ground station, so that access paths are different even though they are the same satellite data. In addition, there is a problem that the format of satellite data generated in each ground station is not unified.
