In analogy with the ultimate speed c, there is an ultimate acceleration B, nobody's acceleration can exceed this limit B, in the solar system, B=2.956391e+10(m/s2). Because this ultimate acceleration is a large number, any effect connecting to B will become easy to test, including quantum gravity tests. In this paper, an approach is put forward to connect the ultimate acceleration with quantum theory, as an application, the quantum gravity theory with the ultimate acceleration provides a useful formula to calculate the space debris distribution around the earth, in this paper the calculation results agree well with the experimental observation. Between February 2018 and 2022, SpaceX successfully launched 2,091 satellites into orbit. In March 2020, SpaceX reported producing six satellites per day. Comparing to the space debris distribution, Starlink satellite altitudes are analyzed, some suggestions can be made to improve the Starlink constellation design and status by the quantum gravity theory with the ultimate acceleration.
