Abstract:
The present invention relates to a method and an apparatus for providing flag data by GPS data analysis and, more specifically, to a method and a system for providing flag data by GPS data analysis, which records and provides a pre-processing flag having a history of a pre-processing process of ionospheric delay estimation by pre-processing of GPS carrier data for each ground station, and monitor an actual ionosphere abnormality by checking the recorded pre-processing flag. According to the present invention, the method can judge whether data having an extreme ionosphere slope is resulted from an actual ionosphere abnormality, or a receiver fault or a material processing error using the recorded pre-processing flag. Also, the method can mitigate load under rising pressure in a process for judging validity of the ionosphere abnormality manually, by maximally automating an auto screening process which removes candidates which are not automatically an actual ionosphere abnormality among the candidates judged as an ionosphere abnormality.

Abstract:
PURPOSE: A method and a device for forming the curvature of a board are provided to precisely form metal boards with various thicknesses and shapes, and to improve the quality of a curved surface. CONSTITUTION: A method for forming the curvature of a board is as follows. A first drive roll row(20) of a first roll set and a second drive roll row of a second roll set are crossed each other. The second drive roll row and idle roll rows(30,31) support a board transferred between the first roll set and the second roll set. The first drive roll row presses the board.
