Abstract:
1. A method of distributing weather forecast data from an artificial broadcast or communication satellite comprising: receiving a source signal from an on-earth transmission station; relaying the source signal towards the earth without using any on-earth network; receiving response signals from a plurality of on-earth receiving stations, the response signals comprising position data of the respective on-earth receiving station and an amount of attenuation caused between the artificial broadcast or communication satellite and each of the plurality of on-earth receiving stations, respectively; transmitting the response signal from each of the plurality of on-earth receiving stations to a weather forecast center by the artificial broadcast or communication satellite; receiving, at the artificial broadcast or communication satellite, the local and wide-area weather forecast, from the weather forecast center generated based upon the response signals from each of the plurality of on-earth receiving stations and by taking data other than receiving state data into consideration including at least one of temperature data and humidity data in an area in which a respective on-earth station is located, the at least one of temperature data and humidity data being obtained by the respective on-earth station, and distributing the local and wide-area weather forecast towards the earth from the artificial broadcast or communication satellite, and wherein on-earth stations within a predetermined distance from said weather forecast center transmit the at least one of temperature data and humidity data directly to said weather forecast center, and wherein the at least one of temperature data and humidity data is included in the response signal for on-earth stations located at a distance greater than the predetermined distance from said weather forecast center.
