By comparing the relative trajectory calculated by the Lawden’s equations and that by numerical integral method, it is concluded that the homogenous solutions of Lawden’s equations are non-periodical, and the initial condition, which is selected to satisfy the periodical solutions, is a compulsory one irrelevant to the condition of long-term formation flying.
