一种载人飞船自主应急返回控制参数星载计算方法

A Fast Algorithm of the Control Parameters on Manned Spaceship for Emergency Return

传统的飞船应急救生控制参数是在地面计算生成并上传到飞船上的,这种方法对频繁进行轨道调整的飞船并不适用,本文探讨一种新的飞船自主应急救生控制参数计算方法,利用船载GPS资源进行快速轨道外推,并使用解析方法和神经网络方法计算返回控制参数,以适应复杂飞行任务的要求。

The emergency return control parameters are generally calculated and accomplished on the ground in the flight missions of the manned spaceship.However,this method cannot resolve the requests of the complex flight missions,especially when the orbit is adjusted continually.A new method combined with GPS orbit prediction,analytics and neural network is proposed to settle the future situation.
