A low-thrust guidance scheme, which is weighted combined by taking the optimum strategy of thrust allocation and the target deficits value into consideration for each orbital element, is developed. The presented guidance scheme is predictive in nature and does not rely on a stored reference trajectory or reference controls. The orbit transfer problem is converted into parametric optimization and utilizing a hybrid genetic algorithm. The minimum-time orbit transfer is considered. The influence of the Earth’s oblateness is taken into consideration in the simulation of minimum-time. A conclusion is drawn that the designed method presented here turns out to be an autonomous scheme because the information of target orbit is considered in the transfer process.

Low-thrust spacecraft orbit transfer optimization problem is studied in this paper, and shooting method is applied to the transfer trajectory optimization for satellites on high eccentric orbit. First, this paper puts forward the gauss perturbation equation of non-singular equinoctial elements. A first order approximated analytical solution of the orbit elements under low-thrust and J2 perturbation is presented based on perturbation theory. Then, the optimization control model by shooting method is established. Finally, the first order approximated result is compared to the numerical result. A transfer problem is optimized using shooting method. The accuracy and validity of this method is verified.

With radar and surface-to-air missiles posing an increasing threat to on-orbit spacecraft, low-observable satellites play an important role in low-thrust transfers. This paper presents the design for a low-thrust geostationary earth orbit (GEO) transfer control strategy which takes into consideration the low-observable constraint and discusses Earth shadow and perturbation. A control parameter optimization addresses the orbit transfer problem, and five thrust modes are used. Simulation results show that the method outlined in this paper is simple and feasible and results in reduced transfer time with a small amount of calculation. The method therefore offers a useful reference for low-thrust GEO transfer design.
