Research of the inertial navigation system with variable damping coefficients horizontal damping networks

This work discusses the choice principles and methods of optimal 2-order horizontal damping network (HDN) in inertial navigation system, gives out optimal 2-order horizontal damping networks in various damping coefficients, and reduces the integrated inertial mathematic model of navigation system. By simulation, it shows that the inertial navigation system with variable coefficients horizontal damping networks has higher precision in motion voyage.
