Summary: | An algorithm to automatically extract coordinate and time information from optical observation data of geostationary orbit
satellites (GEO satellites) or geosynchronous orbit satellites (GOS satellites) is developed. The optical wide-field patrol
system is capable of automatic observation using a pre-arranged schedule. Therefore, if this type of automatic analysis
algorithm is available, daily unmanned monitoring of GEO satellites can be possible. For data acquisition for development,
the COMS1 satellite was observed with 1-s exposure time and 1-m interval. The images were grouped and processed in
terms of “action”, and each action was composed of six or nine successive images. First, a reference image with the best
quality in one action was selected. Next, the rest of the images in the action were geometrically transformed to fit in the
horizontal coordinate system (expressed in azimuthal angle and elevation) of the reference image. Then, these images were
median-combined to retain only the possible non-moving GEO candidates. By reverting the coordinate transformation of
the positions of these GEO satellite candidates, the final coordinates could be calculated. |
