Other AbstractCube-Sat is the research focus in the field of micro satellite in recent years. In this paper,mission that with a cube-sat in the Sun synchronous orbit ( SSO) is taken as an example,then the orbit evolution of SSO cube-sat is studied considering both the influence of atmosphere drag and that of J_2 coefficient (the Earth' s oblateness perturbations to the second-order zonal coefficient). Orbit altitude , solar activity index and atmosphere models are researched respectively to show their impacts on the evolution of orbit,and numerical simulations are carried out. The work above indicates some conclusions as follows : perturbation force that produced by air drag plays an important role to decide the lifetime of SSO cube-sat , and there is a nonlinear relationship between the orbit altitude and the magnitude of orbital decay which is induced by atmosphere drag. Orbital decay based on high solar activity is obviously different from that based on low solar activity, and the relationship between F10.7 and the magnitude of orbital change is not linear. Considering various air drag models separately, the orbit evolutions are not equal,but their order of magnitude are almost the same. The analysis above is helpful to both the orbital choosing of SSO CubeSat and its orbit control.
