Abstract: The earth horizon sensor apparatus uses first and second linear sensor arrays of sensor elements, the first and second linear sensor arrays being staggered with respect to each other. The sensor elements are preferably pyroelectric elements for detecting the presence or absence of infrared radiation from the Earth and Space. A microprocessor is used to determine which of the sensor elements subtends the diffuse horizon gradient and the constant zero radiance of Space. The attitude of the spacecraft is thereby calculated.
