The method can be suitable for the design of a multi-satellite positioning and orbit determination system for space-based space target monitoring, can also be popularized and applied to the design of a space-ground multi-satellite multi-station combined positioning and orbit determination system, can rapidly and quantitatively evaluate the space target positioning and orbit determination result under different constellation designs, is clear in principle, is simple in calculation, is accurate in evaluation, and can be widely applied to a space-based space target monitoring system.

Description

technical field [0001] The invention relates to the technical field of space target monitoring, in particular to a rapid analysis method for multi-satellite positioning and orbit determination accuracy of space-based space target monitoring. Background technique [0002] Space-based space target surveillance is an important development direction in the field of space target surveillance, and it has advantages that many ground-based detections do not have, such as high detection frequency and good observation conditions. Space-based space target surveillance satellites can theoretically carry various types of detection loads such as radar, optical and passive reconnaissance. Since the miniaturization of long-range surveillance radars is not yet mature, most of the surveillance satellites are actually optical surveillance satellites and passive reconnaissance satellites. Receive satellite. Different from radar detection, optical surveillance satellites and passive reconnaissa...

AI Technical Summary

Problems solved by technology

Different from radar detection, optical surveillance satellites and passive reconnaissance satellites can only obtain angle measurement information, but cannot obtain ranging information, and cannot obtain the target position through a single measurement. It is difficult to perform real-time target indication and high-precision short-arc orbit determination tasks Larger, and the theoretical accuracy of satellite positioning and orbit determination needs to be calculated through a large number of numerical simulations, which has low efficiency and poor versatility, and is not suitable for rapid constellation design
