Simulation of the space conjunction of a Chinese mega-constellation with other space objects

At present, there are 90 member satellites of a Chinese mega-constellation in space. More member satellites will be deployed in space in the future. It is quite crowded in near-Earth space since there are many low-Earth orbiters in this space. Authors have focused on simulations of space conjunctions of mega-constellations with other space objects. The main orbit elements are presented in form of graphics, which could show the general deployment situation of the mega-constellation; based on orbit data set, authors have simulated the possible conjunctions, which include NORAD catalog number for objects, object names, time of closest approach, minimum range and maximum probability, relative speed. These simulations will support the effective operation and smooth deployment of follow-up member satellites.
