OBSERVATION SYSTEM MOUNTED ON ATRIFICIAL SATELLITE FOR OBSERVING OZONE LAYER

摘要

PROBLEM TO BE SOLVED: To efficiently observe an ozone layer in view points of a time and a cost.;SOLUTION: An OBC 10 finds sunrise/sunset times in an orbit and times navigated in sun shine/shading partions, based on a position in a change of shading and sun shine during one cycle detected by a solar sensor 12 for posture control, and a disclosure time and a finish time of observing the ozone layer in the next cycle and thereafter are calculated in the artificial satellite based on a data found therein. A sunlight incident angle to an ozone observation equipment 5 is calculated based on an angle data of angles formed by respective visual-field centerlines of the known ozone observation equipment with respect to an advancing direction of the artificial satellite, and based on a sun- directional angle data detected by the solar sensor.;COPYRIGHT: (C)2003,JPO
