Abstract:
A communication satellite group (44), formed of infrastructure satellites which each fly in an earth orbit (LEO), flies, in a substantially equal arrangement, an orbit that has an orbital altitude and an orbital inclination for forming a sun-synchronous orbit for orbiting an integral number of times per day. The communication satellite group (44) comprises: a first satellite (61) which communicates with a ground facility (701); a second satellite (62) which communicates with a monitoring satellite (521); and a third satellite (63) which communicates only with the communication satellites flying immediately ahead and behind. The monitoring satellite (521b) and the ground facility (701) carry out transmission and reception of information therebetween via the communication satellite group (44).
