Abstract

The invention relates to a space trajectory conflict monitoring method, device, equipment, and medium. By performing space discretization processing on the space motion equation of an object, the original problem of solving multivariate equations is changed into a space retrieval problem. It avoids the complex solution process of multi-object trajectory equations, and only needs to discretize a single equation to the space grid. When the number of objects increases, it only needs to be processed once, thus effectively improving the efficiency of multi-object space trajectory conflict monitoring. .

Description

technical field [0001] The invention relates to the field of space track conflict monitoring, in particular to a grid-based space track conflict monitoring method, device, equipment and medium. Background technique [0002] At present, in the large-scale use of unmanned equipment, space trajectory conflict monitoring is required to avoid collisions. Traditional monitoring methods calculate whether there is an intersection point between the trajectory motion equations of each object. However, when the number of objects increases, new object motion equations are required Computing the intersection points of trajectories between two pairs with the existing motion equations of objects, the calculation amount increases significantly with the increase of the number of objects, which brings great difficulties to monitor the conflict of multi-object space trajectories. [0003] Therefore, there is an urgent need in the art for a technical solution for monitoring space trajectory con...
