实现火箭弹空间定位的GPS工作平台动力学仿真

The Dynamical Simulation by GPS Worktable Realizing Rocket-Projectile Space Orientation

全球定位系统(GPS)可以实现全球、全天侯连续导航定位,为用户提供高精度的三维空间位置(海拔高度、经度及纬度)及精确的时间信息。利用 GPS 系统测量火箭弹的空间位置坐标,其误差与飞行距离无关,其精度是简易惯性陀螺无法比拟的。文中提出了在旋转火箭弹上使用 GPS 的一种新的方案,并通过系统仿真,证明这种方案是可行的。

Navigation satellite timing and ranging/Global Positioning System(GPS)can realize global and continuous all-weather navigation,and provide high precision 3-D position(height above sea level,longitude and latitude)and split-second precision for user.To measure rocket-projectile s 3-D location coordinate by means of GPS,the measuring error is independent of its flight distance.The precision is higher than simple control and guide inertia peg- top.The paper puts forward a new method that GPS is used in the rot...
