Abstract:
A global information providing system comprising a first processing system which performs positional computing with global information data from global positioning satellites and outputs results thereof, a second processing system which performs processing of the global information data from weather or remote sensing satellites and outputs image data therefrom, and a third processing system which includes a memory unit for storing image data of aerial photograph and video image, whereinsaid first processing system is provided with a correlator which determines time difference data based on a C/A code included in the global information data sent from the positioning satellites, and a position computing unit which performs positional computing based on the time difference data determined by said correlator and outputs a result,and said second processing system is provided with a wavelength/reflectance correlator for generating a spectroscopic curve of wavelength and reflectance for global information data sent from the weather or remote sensing satellites and a correction unit for correcting the data sent from the weather or remote sensing satellites with respect to noise and distortion caused by sensors or scanners mounted on the weather or remote sensing satellites, and temperature and light amount in data transmission space.
