Infrared earth horizon sensor
WebbIt was used, in conjunction with an electronics package, to sense the position of the Earth's horizon relative to the capsule's position in orbit. It contained a pivoting mirror, lens, … WebbAbstract. Infrared Earth horizon sensors are capable of providing attitude knowledge for satellites in low Earth orbit by using thermopile measurements of the Earth’s infrared emission to locate the Earth’s horizon. Because some small satellites, such as CubeSats, have limited resources, a framework was developed that improves the attitude ...
