ABSTRACT:
In a direction detecting device, a laser beam emitting source for intermittently emitting a laser beam is provided in one satellite, image data including a laser beam image in emitting and non-emitting states of the laser beam from the laser beam emitting source is obtained by an optical system and an image pickup section provided in the other satellite, image data of the laser beam non-emitting state is stored in a memory section, stored image data of the laser beam non-emitting state and image data of the laser beam emitting state are subtracted to extract only a laser beam image, thereby detecting a direction of the laser beam emitting source based on the extracted laser beam image.
