| 摘 要： | 针对某型制导火箭弹的工程化研制，研究了GPS在制导火箭弹中应用时不同坐标系间的转换关系，详细推导了由地固坐标系到发射坐标系和东北天坐标系到发射坐标系之间的转换关系。通过实例验证了该转换关系的计算精度满足控制系统的使用要求，同时给出了控制系统参数输入的程序设计流程图。研究结果可为制导火箭弹在制导控制过程中将GPS数据直接转换为控制系统所需的坐标值提供依据。

| Abstract: | Based on the engineering background of a certain guided rocked missile, the transform relationship in different coordinate was investigated while GPS was used in rocked missile. The relationship of transformation of the earth fixed coordinate and the emission coordinate is detailed, at the same time the coordinate transformation of the east north top coordinate and the emission coordinate is given, and it verifies that the accuracy of the transformation meets the demand of the control system by using the practical example, and then the graphic of the program design of the control system is given. Experimental results could provide reference value for guided rocked missile coordinate conversion using GPS as direct guided method. |
