Visible/Near-Infrared Composite Target Star Simulator

Principle Overview

• The dynamics simulation computer sends the current attitude information of the star sensor to the star map simulation device’s control computer via a communication interface (or the control computer independently generates random attitude information). The control computer converts the received attitude data into optical axis pointing. It then identifies eligible navigation stars from the navigation star catalog within the specified field of view, performs coordinate transformation, and displays the simulated star map simultaneously on the control computer’s monitor and the DMD through interfaces and drive circuits. Finally, the collimated optical system emits the star map as parallel light to simulate a starry sky background, meeting the corresponding field-of-view matching requirements of the test equipment’s star sensor and the system’s high-dynamic simulation needs.
