Abstract
The large field survey optical telescope system has strong spatial target information acquisition capabilities. Wide-angle telescope array as a typical large-field survey optical telescope system, can be used for the general survey of space targets, access to important parameters such as orbital parameters and shape and size parameters, is a powerful tool to grasp the spatial situation. In order to analyze the tracking effect of the wide-angle telescope array on the typical orbit of the space target and explore the best use scheme, this paper designs different combinations of field of view for the space configuration and geometric characteristics of the typical orbit of the space target. Simulate the census capabilities of the wide-angle telescope array. First, establish a typical orbit model for space targets. In the database, the data of the typical orbital parameters of the space target are collected, typical orbital parameters are selected according to the data characteristics, and a typical orbital model is constructed. Second, design the field of view combination. According to the data characteristics of different orbital parameters, different visual angles of wide-angle telescope arrays are designed. Finally, simulation census capabilities. The ability to determine the orbit and the time required for the census are taken as important indicators of the census capability. The census capabilities of the combination of field of view methods under different typical orbit conditions are simulated. The simulation results show that the wide-angle telescope array has a very strong census capability. Designing different combinations of field of view for different orbital features can improve the orbit determination accuracy of the wideangle telescope array, and at the same time greatly improve census capabilities.
