| Abstract: | Based on the developments of GPS attitude determination, a new INS/GPS integrated navigation system is designed, which adopts the position, velocity and attitude as its measurement variables. The paper deduces the observation equation of this new integrated navigation system in detail and applies this INS/GPS integrated navigation system into an aircraft. Simulation results show that the evaluation precision and the quickness of the navigation parameters were effectively improved in the new integrated navigation system. |
