A series of river trials are carried out to verify the feasibility of the velocity matching method and the velocity plus attitude matching method. First of all, a hardware-in-the-loop simulation system is designed in this paper. Secondly, the kalman filter models for velocity matching and velocity plus attitude matching are introduced. Four types of river trials are done, respectively, velocity matching...
With the development of the dynamic base transfer alignment how to resolve accuracy evaluation is significantly important to determine transfer alignment program and value navigation system performance. The smoothing algorithm is a method to evaluate accuracy evaluation. This paper deeply analyzes the method which adopts fixed-point and fixed regional smoothing technology to evaluate the accuracy...
