摘　　要：导航单元是空投系统能够精确地将物资投送到指定地点,并安全实施雀降的重要保证。在总结国外相关导航方案的基础,同时结合特殊条件下的空投要求,提出了将IMU/GPS同时辅以激光测距计的组合方式应用于空投系统。利用卡尔曼滤波技术,得到高精度的速度、位置信息,并通过Matlab仿真对导航结果进行了验证。结果证明满足了空投对导航精度的要求。Navigation unit is the guarantee that airdrop system can deliver supplies to the designed place accurately and implement landing safely. On the basis of relevant foreign navigation scheme and dropping requirements for the special conditions, the scheme is proposed that combine IMU/GPS and laser distance meter for the airdrop system. Kalman filtering technique is used to obtain High-precision speed and position information, and simulation results are proved to meet the requirements of precision airdrop to the navigation.
