Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back The method of inertial navigation systems output errors calculation without input errors simulation V.S. KIRILLOV The output errors calculation method of inertial navigation systems of different algoritms, operating principles and information gauges types with input errors modeled as Gaussian Marcovian processes is developed. This method is based on the transformation to output errors correlation equations. It doesn’t request input errors simulation. The differential equations system for correlation is solved by appropriate for rigid systems and possessing L-stability property numerical method (In the article the second order Gyre method is used). The comparison with analytical solution for platform inertial navigation system with the geographical basic and navigation trihedron and motionless located on the equator object. Keywords: inertial navigation system, stochastic dynamical system, Langeven equations, Gaussian marcovian process, transformation to correlation equations, rigid system, L-stability, second order Gyre method.
