Abstract:
According to an embodiment of the present invention, a triple-band antenna system for satellite communication includes: a feed horn device which radiates or absorbs triple-band wireless signals including X, Ku, and Ka bands at the same time; and a wave guide unit which is combined to the feed horn and transmits input/output of the wireless signals. The feed horn device includes: a corrugation horn which radiates or absorbs wireless signals in the X and Ku band, has a bell shape, and has a plurality of stepped corrugations on the inner circumferential surface; and a dielectric feed which radiates or absorbs wireless signals in the Ka band and is placed at the central area of the corrugation horn.
Abstract:
The present invention relates to a device and a method for computing a route in consideration of a satellite communication state comprising: a step for searching multiple subroutes reaching a destination; a step of analyzing the receiving sensitivity of radio waves receiving from a satellite to analyze the satellite communication environment of each subroute; a step for selecting a first route among the subroutes based on the analyzed satellite communication environment; and a step of mapping the first route on a map and outputting the map on a display part. [Reference numerals] (S110) Searching multiple subroutes reaching from a departure to a destination;(S120) Analyzing the satellite communication environment of each subroute;(S130) Selecting a first route among the subroutes based on the analyzed satellite communication environment;(S140) Outputting the first subroute on a display part.
