Abstract: Star sensors, a kind of attitude measurement equipment with stars as reference sources, are widely used on satellites, missiles, ships and other platforms. For near-earth space platforms that need to work all-time in the atmosphere, such as ships, aircraft, missiles, and high-altitude balloons, star sensors are faced with the difficulty of detecting dim stars against the strong sky background. This paper first describes the basic working principle of all-time star sensors in near-earth space, followed by an introduction of the research status at home and abroad. The main technical approaches are analyzed and summarized, and the development trend is discussed. The analysis results can provide reference for and facilitate the development of all-time star sensor systems in near-earth space.

Key words: navigation, star sensors, stellar detection sensors, atmosphere, all-time
