  • METHOD FOR SOLVING ATTITUDE OF RIGID BODY BASED ON FUNCTION ITERATIVE INTEGRATION
    Publication number: 20210404811
    Abstract: The present disclosure provides a system and a method for solving an attitude of a rigid body based on function iterative integration, including: step 1, fitting a polynomial function of an angular velocity according to a gyroscope measurement value over a time interval; step 2, iteratively calculating a Rodrigues vector by using the fitted polynomial function of the angular velocity and a Rodrigues vector integral equation; and Step 3, and obtaining an attitude change over the time interval in terms of quaternion according to the final iterative result of the Rodrigues vector.
