Currently, star sensors are mainly developed for aerospace navigation. The necessity, the technical difficulties, and the effects to be achieved of applying them to single-soldier navigation still remain unclear. This paper first discusses the necessity of developing single-soldier star sensor navigation equipment: It can serve as guarantee equipment when other navigation equipment fails because it cannot be damaged by electromagnetic interferences; Its high directional accuracy can compensate for the orientation deficiency of single soldier satellite navigation equipment; It enables all-time, all-weather navigation with its ability to overcome certain meteorological factors. Technical characteristics of the single-soldier star sensor navigation are compared with those of the aerospace star sensor navigation, satellite navigation, and astrogeodesy. Key technologies in developing single-soldier star sensor navigation equipment are then presented, including reduction of meteorological influences, long-term maintenance of time datum and power supply, balance of system detection performance and system miniaturization. The results provide reference for the development of single-soldier star sensor navigation technology and the design and development of single-soldier star sensor navigation system.
