Abstract:
A direction detecting device comprising:first and second space vehicles moving in space;a laser beam emitting source, mounted on said first space vehicle, for intermittently emitting a laser beam to space;image data generating means, mounted on said second space vehicle, for obtaining an optical image including the laser beam from said laser beam emitting means to generate image data;storing means for storing image data of a laser beam emitting state of image data generated by said image data generating means;laser beam image extracting means for subtracting image data of a laser beam non-emitting state from said image data of the laser beam emitting state stored in said storing means to extract a laser beam image; anddirection detecting means for detecting a direction of said laser beam emitting source based on the laser beam image extracted by said laser beam image extracting means.
