<P>PROBLEM TO BE SOLVED: To provide a space optical transmission apparatus which achieves high-speed simultaneous space optical transmission with respect to a plurality of terminals. <P>SOLUTION: In a space optical transmission apparatus 110, a light receiving section 120a, 120b receives an optical signal from a terminal. A control section 121 estimates how much optical axes of a master station 110 and the terminal are deviated from each other, based on the received optical signal. The control section 121 selects one of a plurality of light sources 111a, 111b, 111c which requires a smallest amount of shift of an optical axis thereof, based on the estimated optical axis deviation amount, so as to communicate with the terminal. <P>COPYRIGHT: (C)2007,JPO&INPIT |
