Claims

[Scope of utility model registration request]

A satellite attitude detection device installed on a three-axis stable satellite that detects the satellite's attitude with respect to a target object such as the earth uses a mirror that vibrates at a constant amplitude relative to the target object and an infrared ray that detects infrared rays from the target object. a detector, an attitude signal generation device that generates an attitude signal in one axis direction of the satellite relative to the target based on the detection signal from the infrared detector, and a turntable that rotates every 90 degrees on which a vibrating mirror and infrared detector are mounted. , a stepping motor that drives it, and an attitude signal that outputs an attitude signal of the satellite in two axes based on an attitude signal in one axis direction of the satellite outputted from an attitude signal generation device and an angle signal outputted from the stepping motor. A satellite attitude detection device comprising: an analysis device;
