This invention discloses a fused red dot sighting system, comprising an infrared mirror group, a liquid crystal display screen, a prism, a first lens group, a reflector, a second lens group, a beam splitter, and an eye point arranged sequentially along the optical path. The prism has an inclined surface facing the first lens group, and a red dot light source is arranged above the inclined surface. This allows the light from the red dot light source and the infrared light from the infrared mirror group to be fused on the prism before being transmitted to the beam splitter and entering the human eye. The infrared mirror group captures an image of the external target, which is then displayed on the liquid crystal display screen. The image on the liquid crystal display screen and the light emitted by the red dot light source are fused on the prism. The fused light passes through the first lens group to complete the first imaging, then passes through the reflector to effectively shorten the volume, and finally passes through the second lens group to reach the beam splitter. At this point, the fused optical path of the infrared light and the red dot light is deflected on the beam splitter and enters the eye point to achieve a second imaging.

This invention relates to a supportless aiming system and method for large launch vehicles. The system includes a laser strapdown inertial navigation system (INS) and an autocollimating beam fixed on the INS. The INS autonomously seeks north and calculates the azimuth angle of the autocollimating beam based on the north direction and the positional relationship between the beam's coordinate system and the INS coordinate system. The autocollimating beam emits light towards an aiming prism and measures the prism's deviation angle. The INS also calculates the azimuth angle of the aiming prism based on the azimuth angle of the autocollimating beam and the prism's deviation angle. The azimuth angle of the autocollimating beam is the angle between its axis and the north direction. The deviation angle of the aiming prism is the angle between the prism's normal and the autocollimating beam's axis. The system has the advantages of simple structure, low cost, and accurate aiming. The method has the advantages of high automation and good safety.
