Strip running stabilization device of hot dip galvanizing line

摘要

The present invention relates to an elliptic orbit satellite network for mobile communication service which provides personal communication network service by emitting nine artificial satellites to three elliptic orbits. In this network, three elliptical orbits are used, and orbital period is 205.7 min. Three satellites are used for each orbit, and the orbit inclination angle is 45 degrees. The mean motion of the satellite is 7, and the eccentricity is 0.4 while ARG perigee is 270 degrees and the ARG height is 547.9 [km . The distant height is 97.82.7 [km .
