The invention provides a real-time searching method for a fixed star around the directional position of a photoelectric tracking measurement device and mainly relates to the field of photoelectric tracking measurement and high-precision equipment guiding control. For the object tracking process, observation of fixed stars around the track is required. The invention designs a method to achieve the target tracking and to timely search fixed stars in a certain field angle range away from a target. The method uses the feature that the star position is basically constant in the second equatorial coordinate system, and avoids the problems that as the star and the target are moving in the level coordinate system, the calculation amount is large and the search complexity is big and so on. Through the virtual star, the relevant error is calculated to achieve the direct search in the star table, thereby reducing the search volume and improving the search efficiency and the hit rate of searching.
