摘要
为提高导航精度和抗干扰能力,设计"CDMA+捷联惯导(INS)"组合导航系统。该系统利用INS数据进行参考轨迹确定。CDMA独立数据采集,在INS参考位置基础上提取到达时差(TDOA)信息,用TDOA算法精确定位,校正INS积累误差,实现了隐蔽性好,抗毁能力强,经济实用等特点。
In order to improve navigation accuracy and anti-jamming capability,＂CDMA ＋ INS＂ navigation system is designed.The system used INS data to determine the reference trajectory.CDMA collected data independently,got TDOA information from the reference position by INS.Precise positioning based on TDOA algorithm,can improve accumulation error of INS,hiding capability,invulnerability ability,and achieve economic and practical features are realized.
