Typically coning motion has been used as the input to test the effectiveness of attitude algorithms. Jacobian elliptic functions are also shown to meet the criteria for a test input. Simulations using several of these inputs are performed on Miller's algorithm. Analytical evaluation of a Jacobian elliptic function input would be prohibitive. To alleviate this problem Richardson extrapolation is used to numerically evaluate the algorithms for each test input. Additionally, a method for improving all of the attitude algorithms using interpolation is presented. References: 5
