The method creates an all-weather navigation astronomical observation skill training environment, strengthens astronomical navigation skill training, ensures that astronomical navigation technology is available in war time, and is an urgent requirement for further strengthening navigation guarantee capability of army in war time.

For the above reasons, it is necessary to develop a simulator that can simulate the functions of a marine sextant and develop daily training indoors. Based on the principle of the original navigation sextant, the product combines virtual scenes and various sensors to simulate various scenes of normal use of the navigation sextant, can be conveniently used for measurement and training, and achieves the purposes of convenience and high efficiency.
