To provide a monitoring system that can continuously monitor the globe using a small number of satellites and has high monitoring performance including spatial resolution performance.SOLUTION: A communication satellite 201 has a first optical communication device 51C that performs optical communication with a satellite in front thereof, a second optical communication device 52C that performs optical communication with a satellite behind the device, a third optical communication device 53C that performs optical communication with a satellite flying toward northeast on an east-side adjacent orbit, a fourth optical communication device 54C that performs optical communication with a satellite flying toward southwest on a west-side adjacent orbit and a communication device 55C that performs communication with a monitoring satellite 100 while being oriented in a -Z direction, when passing toward north above the equator. An Azimuth communication visual field of the third optical communication device 53C is ±90 degrees or more with respect to a +X axis direction. An Azimuth communication visual field of the fourth optical communication device 54C is ±90 degrees or more with respect to a -X direction. A communication visual field in which the communication device 55C performs communication with the monitoring satellite 100 is ±60 degrees or more around the +X axis with respect to the -Z direction and is ±60 degrees or more around a +Y axis.SELECTED DRAWING: Figure 13
