Design method of small thrust phase modulation maneuver on elliptic orbit

Abstract

The invention relates to a design method of a small thrust phase modulation maneuver on an elliptic orbit, and belongs to the technical field of spacecraft orbital maneuvers. The method comprises the steps of proposing two feasible phase modulation policies based on a rule of an influence of the thrust direction on a phase change of a spacecraft, simplifying the complex phase modulation maneuver to an optimization problem only containing three parameters by using techniques such as constraint relaxation and orbit equalization, and conducting simplification processing on a design model according to the characteristic of a small-thrust elliptic orbit phase modulation task by adopting the orbit equalization technique and neglecting the secondary constraint, so as to efficiently and rapidly obtain the initial value of an elliptic orbit phase modulation maneuver parameter. The method has the advantages that the method is simple in algorithm, high in robustness and high in computational efficiency. The method is applicable to the initial design of the small thrust phase modulation maneuver on the same elliptic orbit, and the initial design of the phase modulation maneuver between different elliptic orbits with smaller orbit deviation.

Description

technical field [0001] The invention relates to a small-thrust phase adjustment maneuver design method on an elliptical orbit, and belongs to the technical field of spacecraft orbital maneuvering. Background technique [0002] The phase modulation section is an important part of space rendezvous and docking, geosynchronous satellite orbiting and other missions, and the phase modulation maneuver design is an important part of the design of such missions. According to the current propulsion technology, there are two ways to realize the phase modulation task: traditional pulse engine and small thrust engine. In comparison, the low-thrust engine has high specific impulse and light weight, which can effectively reduce fuel consumption during the phase modulation process and has more technical advantages. However, the long working time of the small-thrust engine and the non-Kepler orbit under the action have also brought difficulties to the design of phase adjustment maneuvers. ...
