Description: The dynamics of orbit uncertainty in an unstable orbital environment are discussed
with specific application to the orbit determination of a halo orbit about
the Earth{Sun L1 point. This article documents a simplified orbit determination
covariance program developed under Telecommunications and Mission Operations
Division Technology support. The program is ideally suited to investigate spacecraft
trajectory navigation in challenging environments, where the basic dynamics
of the trajectory can no longer be modeled using near-Keplerian motion. Platform: |

Description: 这个课题设计从地球的近地轨道起飞到达谷神星预定轨道并且着陆在其表面上的一种数值方法。基于有限时间的航行纠正点火而非瞬时推力数值计算和Matlab仿真。最后可以看到空间飞行器从地球的影响球飞到谷神星的影响球的飞行轨迹。-This project explores the mathematical methods and results of designing a mission to land a spacecraft on the asteroid Ceres by beginning in an earth-centered LEO orbit and ending in an orbit prepared to land on the surface of the asteroid. Rather than assume instantaneous velocity changes, course-correcting burns of finite time are considered and analyzed using numerical methods and Matlab computation. The behavior of the spacecraft is observed inside the Earth s sphere of influence, in interplanetary space, and inside Ceres sphere of influence. Platform: |

Description: The ballistic category of atmospheric vehicles includes missiles, launch ve-
hicles, and entry capsules. Some missiles and launch vehicles incorporate fi ns
as aerodynamic stabilizing and control surfaces. The spacecraft are also catego-
rized according to their missions, such as low-earth orbit, medium-earth orbit,
geosynchronous orbit , lunar, and interplanetary spacecraft. Each mission is
defi ned by the payload, and orbital elements of the fi nal orbit. Of course, a
reusable launch vehicle, such as the space shuttle, is also a spacecraft with a
unique mission. -The ballistic category of atmospheric vehicles includes missiles, launch ve-

Description: The Spacecraft Control Toolbox is composed of MATLAB m-fi les and mat-fi les, organized into a set of modules by subject. It is essentially a library of functions for analyzing spacecraft and missions. There is a substantial set of
software which the Spacecraft Control Toolbox shares with the Aircraft Control Toolbox, and this software is in a module called Common. The core spacecraft fi les are in SC and SCPro along with special plotting tools in Plotting.
The new CubeSat module demonstrates mission planning and simulation for nanosatellites. These fi ve modules are referred to together as the Core toolbox. Functions for estimation, orbit analysis, subsystem analysis, and detailed
attitude control system examples are grouped in separate modules. All of the modules are described in the following table, including the add-on modules which are purchased separately. Platform: |

Description: Goal of this project is to simulate the rotational motion of a spacecraft in orbit. Plots of Euler angles and polhode curves (angular velocity time histories) are generated. Equations of Motion included in this package are for a rigid body in a torque-free environment and in circular orbit. See the EOM section under the Source Code Guide for more information.
The code is designed to be modular. Without getting very fancy, the user only needs to modify sc_attitude, sc_init, and sc_batch, depending on the experiment. Platform: |
