- Abstract
Large constellations have developed rapidly in recent years because of their unique advantages, but they will inevitably have a huge negative impact on the existing space debris environment. According to the existing research results, large constellations will inevitably lead to the deterioration of space debris environment. The key to mitigate the impact is the success rate and time of the post-mission disposal process. Aiming at this problem, this paper further studies the impact of large constellations on other space targets under different PMD strategies through simulation calculation, and puts forward corresponding strategies and suggestions. According to Oneweb's large constellation launch operation plan, the dangerous intersection of large constellation with existing space targets in different stages of its life cycle is calculated by simulation.Based on this, the influence of large constellation operation on existing space targets under different time and strategy of PMD is analyzed. The conclusion shows that the stage of PMD is the stage in which large constellations have the greatest impact on existing space targets; the speed of PMD and number of satellites performing PMD at the same time are the key factors to the degree of the negative impact; The faster the PMD is, the less threat it poses to other spacecraft. More results and conclusions are still being analyzed and calculated.
