A camera array system composed of commercial cameras is applied in the initial orbit determination of space targets. The overview of the camera array system is introduced. Based on the technical characteristics of the camera array, the feasibility for the application of the camera array in the initial orbit determination is analyzed from three aspects: detection capability of space targets, positioning accuracy and improvement of initial orbit determination algorithm. The main process and the experimental verification are provided. The experimental results preliminarily demonstrate the ability for the camera array system to improve the accuracy of initial orbit determination and the detection magnitude of limit exploratory.
