When the hitting range of TBM is greater than a certain degree,the earth's rotation will have a huge impact on the error of trajectory prediction,The kinds of factors that give rise to errors are so many that it's hard to analyze the errors intuitively. In order to analyze the influence of the earth's rotation on the process of trajectory prediction,a random point is selected as the datum point after the rocket engine is shut down in this paper,the coordinate and the velocity vector of this point are obtained. Based on the coordinate system established,the process of the trajectory prediction is decomposed through coordinate transforming and the parameter calculation of midcourse,the trajectory prediction models are established based on the datum point,these models are practical and easy to be realized in engineering. Three-dimensional coordinates of TBM at random time can be predicted through these models after it is detected. We use the data of the trajectory whose hitting range is greater than 1000 kilometers to simulate and to analyze the error of trajectory prediction. The result proves that the earth's rotation will have an impact on the trajectory prediction.
