ABSTRACT:
An earth sensor assembly for an orbiting spacecraft which includes a two dimensional microbolometer area array detector as the detective source for capturing full or partial infrared (IR) images of the earth. The earth sensor assembly further includes an input optic head assembly for collecting incident radiant power emitted from the earth and for directing it to a focal plane of the microbolometer area array. The microbolometer detector converts the detected radiant power into electric signals. Also included are sensor electronics and data processing means for processing the converted signals and determining the attitude of the spacecraft relative to the earth. Also disclosed is an algorithm for processing the earth image information generated by the microbolometer area array and for determining the three axis attitude (pitch, roll and yaw) of the spacecraft.
