Research On Flexible SINS Airborne Error Model Verification Method

SINS system error model in the ground test environment, may be airborne do not apply to the high dynamic flight status. The study Airborne state error model online to obtain more reliable calibration error model for improving the precision of inertial navigation system is of great significance.Therefore, the study of inertial device error model, the incentive error, error model airborne way authentication methods, as well as the required precision of the measurement programme needs, and other related content, as the error simulation model validation test Airborne indispensable important step.SINS system and the principle of the work on the inertial devices and flexible Flexible SINS system error model, demonstrating the validation error model Airborne significance and importance. For the Flexible SINS system error model, studies using of incentives installation error and complex incentive track error, error model to estimate the parameters of the design to the use of an airborne multi-location model calibration parameters of the model error contains proven methods, and simulation verification; through theoretical analysis and the method of combining simulation, verification, tests equipment on the selection of programmes and the needs of the accuracy of measurement solutions for the analyte error model parameters can be provided to achieve Measurement benchmark.In the part of the platform software, in-depth study of the semi-physical simulation platform design methods, as well as the overall function of the structure, design the structure of the various modules and methods. Finally, through the use of integrated development environment software design and development of various modules and functions of real time communication to achieve a flexible SINS system error model validation Airborne semi-physical simulation platform. This simulation platform has a good user interface, real-time communication, sensor simulation, and in accordance with the relevant air-calibration theory and real-time simulation completed Airborne error model calibration function. Flexible ultimately makes SINS system error model Airborne proven methods and simulation platform can be realized.
