Abstract
It's inevitable that the change of data in the large area will introduce the deviation, which will affect the track-ing filter and the state fusion of the target position, course and speed, if the error will not be corrected. In this paper, it was based on the coordinate transformation method of the CGCS2000 coordinate system, including fusion computing public co-ordinate system origin selection method and target state error covariance matrix rotation model. Simulation result showed that the method under the condition of keeping the amount of calculation, could overcome the north pointing error and dis-tance error because of large area cases. Therefore, the accuracy of track fusion and estimation precision were improved.关键词
