Abstract: To present a compact global information providing system which can provide necessary global information without an expensive device in real-time for condition changeable objects, the global information providing system is comprised of a first processing system for positional computing with the global information data and output the result, a second processing system for processing the global information data from the weather or remote sensing satellites and outputs the image data, and a third processing system including a memory unit for storing the image data of aerial photograph or video image, wherein the first processing system is provided with a collelator which determines the time difference based on C/A code included in the global information data sent from the positioning satellites and position computing unit which performs positional computing based on the time difference data determined by the collelator and outputs the result, the second processing system is provided with a wavelength/reflectance
