Claims

[Scope of utility model registration request]

a base body mounted on a flying object and on which an image of the earth is formed;
In an earth sensor that includes an even number of infrared detectors disposed along the periphery of the base body to detect an image of the earth, and generates an attitude error signal of the flying object based on the detection signal of the detectors, each of the infrared detectors and a correction circuit that subtracts the output signal of the temperature detector from the output signal of the infrared detector to correct the signal due to the temperature of the detector itself. earth sensor.
