| Description | Journal: Journal of Physics: Conference Series This paper describes development and modeling of the spacecraft transfer schemes with low-thrust engines from a high-elliptical (with eccentricity up to 0.7 and more) to a geostationary orbit. The problem of orbital elements optimal control is formulated according to Pontryagin maximum principle. We solved the problem of finding the optimal control law using local optimization method. We developed an algorithm and software to solve the problem of flight optimization between non-coplanar orbits. The comparison of calculation results with local optimal control law and precise solutions showed that for a wide range of boundary conditions the results of calculations differ within a margin of no more than 1.5 – 2 %. We given modeling examples of the developed control law for two cases of transfer from high-elliptical to a geostationary orbit. Results of calculations showed that the impact of the atmosphere drag on the transfer time is rather small, because the spacecraft spend a little time in atmosphere bounds and perigee of the orbit is rising above it in few revolutions. |
