摘要

Aiming at the dynamic test requirement of SINS/GNSS integrated navigation system for air-to-air missile in laboratory, a test method for simulating the air motion environment in laboratory is proposed. The performance evaluation tests of missile-borne navigation system based on dynamic transfer alignment and ballistic integrated navigation can be carried out in laboratory. This test method solves the problem that the estimation accuracy of misalignment angle can not be accurately evaluated due to the insufficient excitation of angular velocity and acceleration in ground test, and makes up for the insufficient coverage of ground test of integrated navigation system. The solution of key technical problems in the construction of test system is given, the alignment and integrated navigation algorithm used in the test are explained. Finally, the precision test of transfer alignment and integrated navigation is carried out by using optical fiber inertial navigation and satellite navigation receiver. The test results show that the test method proposed is feasible and practical.
