PROBLEM TO BE SOLVED: To make a satellite direction seen from an earth core when two satellites fly near an orbital plane intersection line approaching while avoiding collision of the satellites regarding a plurality of non-stationary satellites having crossed satellite orbital.;SOLUTION: An amount of difference of a distance from the earth core of two satellites is set and argument of perigee so as to satisfy the amount is determined at the time when respective two satellites of the first orbital satellite, the second satellite and the third satellite can be seen in the approximately same direction when seeing from an earth direction. Eccentricity is determined such that a flight time of the satellite from one orbital plane intersection line to the subsequent orbital plane intersection line becomes 1/3 time of an orbital period. Reference orbital of the first orbital satellite, the orbital of the second satellite and the orbital of the third satellite are set from the argument of perigee and the eccentricity and a retaining range is set around a satellite material point the reference orbital. The retaining range of the respective satellites are overlapped and can pass on the respective orbital surface intersection lines.;COPYRIGHT: (C)2006,JPO&NCIPI
