To make an observable longitude band be a broadband.SOLUTION: An observation system 100 includes an observation satellite 110, a ground facility 130 and a communication satellite 120. The observation satellite 110 includes an observation device, a communication device and a propulsion device and flies along a stationary orbit. The ground facility 130 includes a communication device. The communication satellite 120 includes a communication device and flies along the stationary orbit. The observation satellite 110 and the communication satellite 120 come close to each other till a distance less than 10,000 kilometers and communicate with each other.SELECTED DRAWING: Figure 1
【課題】観測可能な経度帯を広域化できるようにする。【解決手段】観測システム100は観測衛星110と地上設備130と通信衛星120とを有する。観測衛星110は観測装置と通信装置と推進装置とを備えて静止軌道に沿って飛翔する。地上設備130は通信装置を備える。通信衛星120は通信装置を備えて静止軌道を飛翔する。観測衛星110と通信衛星120は、10000キロメートル未満の距離に接近して通信を行う。【選択図】図1
