In our work, the solution is expressed in a finite compact form composed of several definite integrals with varying integration intervals constrained in [0,Tr], in which the traditional Hansen coefficients are no longer involved. Numerical experiments are also given and compared with the traditional series expansion method, and the results show that the derived solution is capable of dealing with highly eccentric orbits. Therefore, the solution given can provide a new technique to analyze the perturbation characteristics arising from the J22 harmonic.展开更多

For the cases in which the transfer energy is conserved, the cost is a much longer transfer time.展开更多
