Observation systems, communication satellites, observation satellites and ground equipment

摘要

The location and time that the observation satellite can transmit the observation data are not limited.The observation system 100 includes an observation satellite 110, a communication satellite 120, and ground equipment 130.The observation satellite 110 comprises a monitoring device, a communication device, and a propulsion device, and observes an observation object while moving the position in the east-west direction with respect to the ground equipment 130 in the orbit along the geostationary orbit.The communication satellite 120 comprises a first communication device for communicating with the observation satellite 110 and a second communication device for communicating with the ground equipment 130, and flies the stationary orbit.The observation satellite 110 communicates with the communication satellite 120 when it flies within a region where the distance from the communication satellite 120 is less than 10000 kilometers.Diagram
