【摘要】 利用全球卫星定位系统(GPS)进行快速、准确的目标定位是炮兵部队提高射击精度和准备速度的重要手段。但 GPS 在使用中必然涉及到不同空间大地坐标系统。本文针对涉及到的不同坐标系统进行了说明,给出了不同坐标系统的定义、相互转换的原理及方法,以最为常用的布尔沙(Boolsa)模型为例,说明了两空间直角坐标系间的具体转换公式及7个转换参数的选择方式和相互关系,同时也给出了同一坐标系统下不同坐标系的定义方法及相互转换公式。更多还原

【Abstract】 Fast and precise location by GPS is an important means for artillery to improve their firing accuracy and preparation speed.However,application of GPS involves geodesic coordinate systems in different space.Descriptions and definitions for different coordinate systems are given in the paper and principle and way of their transformation given as well.Taking the Boolsa model as the example,this paper also makes out the coordinate transformation formulation of two space geocentric coordinates sys- tem and selection and relation of their 7 transformation parameters.At the same time,this paper gives the definition method and transformation formulation of different coordinate systems in the same coordi- nate system.更多还原
