Influence Analysis Of Perturbation Factors On Spacecraft Orbit Design

This issue centers is about the spacecraft's orbit around 200km above the Earth, then begin to fly until the target point of the planet that orbited Mars transfer orbit trajectory design of the orbit task analysis, perturbation factor analysis and simulation applications, it is of great significance and value for precise launch of spacecraft to the target planet.In the proposed interplanetary orbit on the basis of task analysis, focused on the problem of probes based on multi-body dynamic model of the orbit, all kinds of perturbation factors is considered on the orbit design. First, a description of the different orbital parameters and attitude parameters describing the orbit model to analyze the different forms of state describe the computational efficiency of the system and orbit design. Second, given the deep-space probe in which the deep space environment, study the center of the sphere of non-spherical, atmospheric drag, solar pressure and gravity gradient torque and so on, and also perturbation factors have combined a variety of perturbation analysis on the spacecraft orbit Design.Thirdly, based on the established orbital equation, the various tasks involved in orbital perturbations into account, the use of spacecraft control toolbox (SCT) software simulation and analysis, task analysis assumed all orbit section of orbit and adding a perturbation theory, after the orbit and the error analysis, and propose solutions. Designed for the orbit provides a good theoretical basis and experimental basis. Finally, To calculate the interference torques and provide the necessary basis for attitude control of spacecraft.
