摘要
在导弹编队基线测量是导弹集群攻击的前提下,针对导弹编队基线测量问题,提出了一种基于北斗三号DGNSS/RDSS/INS的高性能轻量级基线测量方法。以北斗RDSS区域短报文作为编队数传链路,基于北斗三号DGNSS/INS建立伪距单差观测模型,在GNSS信号连续正常或信号中断情况下,进行DGNSS与INS组合导航实现稳定的基线测量输出。仿真结果表明:在GNSS信号连续正常的观测历元中,DGNSS/INS组合导航可以实现稳定的基线测量输出。在GNSS信号中断20 s以内,DGNSS/INS组合导航在东向(E)、北向(N)的基线测量误差小于2.5 m(1σ),天向(U)的基线测量误差小于3.0 m(1σ)。与RTK算法相比,伪距单差模型对算力的要求降低了70%~80%。
Missile formation baseline measurement is the premise of missile cluster attack.In view of the problems in missile formation baseline measurement,a high-performance lightweight baseline measurement method is proposed based on BDS-3 DGNSS/RDSS/INS.Taking the BDS RDSS short message as a formation data transmission link,a pseudo-range single-difference observation model is established based on the BDS-3 DGNSS/INS.Under conditions of continuous normal GNSS signal or signal interruption,the DGNSS and INS integrated navigation is capable of achieving a stable baseline measurement output.The simulation results show that the DGNSS/INS integrated navigation can achieve stable baseline measurement output in the observation epoch of continuous normal GNSS signal.With the GNSS signal interrupting in 20 seconds,the baseline measurement error of DGNSS/INS integrated navigation in the east(E)and north(N)directions is less than 2.5 m(1σ),and the baseline measurement error in the up(U)direction is less than 3.0 m(1σ).The requirement of pseudo-range single-difference model is reduced by 70%~80%compared with the RTK algorithm.
