The invention provides a wide-area infrared point target detecting and tracking cooperative satellite system which comprises a camera subsystem, a target processing subsystem, a task planning subsystem, an inter-satellite network subsystem, an imaging quality assurance subsystem and a light shield subsystem. The camera subsystem is used for carrying out infrared point target imaging in a wide area range and generating a wide area monitoring range image containing a weak infrared radiation target, and the target processing subsystem extracts a two-dimensional plane coordinate of the target from an infrared image, generates a three-dimensional position and speed of the target and sends the three-dimensional position and speed to the camera subsystem. Different targets are reasonably distributed to different satellites for data fusion; the task planning subsystem calculates orbit positions and observation capabilities of other cooperative satellites according to the three-dimensional position of the target, and performs observation task planning on other cooperative satellites; the inter-satellite network subsystem is responsible for receiving two-dimensional angular trajectories provided by other satellites, providing the two-dimensional angular trajectories to the target processing subsystem, and sending information such as collaborative planning generated by the task planning subsystem to other satellites at the same time.
