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 measure-ment 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 meas-urement output in the observation epoch of continuous normal GNSS signal.With the GNSS signal inter-rupting 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.
