| 摘 要： | 针对高速火箭弹发射出膛瞬间,弹上微机电系统（MEMS）陀螺难以承受上百g的加速度,使得弹上的微惯导系统（Micro-INS）无法完成导航任务,提出用MEMS加速度计构成的无陀螺微惯性导航系统（GFMINS）代替传统MINS与小型GPS构成GFMINS/GPS组合导航系统,实现火箭弹的定位要求.同时,针对GFMINS中角...

| Abstract: | The micro-electro-mechanical systems(MEMS) gyro in the high speed rocket projectile could not bear an acceleration with some hundreds of g while it fires,and so the micro inertial navigation system(Micro-INS) was unable to work for the navigation task.A kind of gyro free inertial navigation system(GFINS) with multiple MEMS accelerometers was proposed to replace the MINS system and small GPS integrated navigation systems to achieve the navigation target.In order to restrain the rapid growth of angular veloci... |
