Abstract

The invention relates to an accurate tracking method for a low-orbit miniaturized dark weak satellite, and relates to the technical field of photoelectric measurement. The method comprises the following steps of camera integration time adjustment, image superposition and data guide tracking based on track prediction. According to the accurate tracking method for the low-orbit miniaturized dark and weak satellite, the detection capability of the low-orbit miniaturized dark and weak satellite can be obviously improved under the condition that the system cost is not increased through a method of increasing the camera integration time and overlapping the images; by using the data guide tracking method based on orbit prediction, the problem that a servo control system cannot realize high-precision tracking of a target due to too low image frame frequency can be avoided, and the precise tracking capability of a low-orbit miniaturized dim satellite is improved.
