Design Study and Simulation on Ship Navigation of RDSS/SINS Tightly Coupled Integrated System
Abstract:Double-star navigation is a regional global navigation system . In order to improve the accuracy of the RDSS/SINS integrated navigation , in this paper ,the integrated navigation system using original measurements of pseudo-range and pseudo-range rate was introduced. Introduces the basic theory of Double-star navigation and builds the math model, the state and observation equation. The simulation results show that this integration method can improve the navigation precision effectively.
Keywords: RDSS SINS tightly coupling pseudo-range and its rate
