standard trajectory

Task of designing reentry trajectory of manned spacecraft is to make standard reentry trajectory and laws of guidance and control according to requirement of task.

载人飞船返回再入轨道设计的主要任务是确定出标准返回轨道和再入制导规律。

A simplified motion model is established in ADAMS software, simulate the processing trace on the ball by different motion parameters, and process the data in the MATLAB, then quantitative analysis the standard deviation of the spherical trajectory point distribution on the ball surface.

在ADAMS软件中建立简化的运动模型，选取不同的运动参数，得到球面加工轨迹点，在MATLAB中进行数据处理，定量分析球面轨迹点分布的标准差。

The statistical covariance method can be used to approximately analyse non-linear system and research the small deviation abut standard trajectory caused by input disturbances. Generally, the result is better than Monte carlo method.

统计协方差法可以用来近似分析非线性系统，研究由输入干扰引起的围绕标准弹道的小偏差，一般效果比蒙特卡洛法好。

The simulation result indicated the control system designed could track the standard trajectory of the GBU quickly, stably and precisely and reject the sideslip flight effectively.

仿真结果表明本文所设计的控制系统能够控制航弹快速、稳定并准确地跟踪标准航迹，并有效地抑制了侧滑飞行。

The present paper discusses the adjustable ability and design method of a standard spacecraft reentry trajectory.
