    Is There a Closed-Form Solution for Attitude Update Equations?

    Hmm, my series is a result of some facts: Omega is a skew-symmetric matrix C is an orthogonal matrix where you have take the transpose of the Peano-Baker series. C itself is the final result. In attitude determination problem, the propagation of C itself and obtaining the C at any instant of...

    Is There a Closed-Form Solution for Attitude Update Equations?

    The last solution that I wrote is solution to \dot{\mathbf{C}}_b^i = \mathbf{C}_b^i \mathbf{\Omega}_{ib}^b starting from the Peano-Baker series itself. And I think I should be able to expand the same thing out by using your formal solution which is no different...

    Is There a Closed-Form Solution for Attitude Update Equations?

    @Kosovtov: Thanks, to be truthful I am not sure it's very helpful, but the furthest that I can go is to write \mathbf{C}_b^n(t) = \mathbf{I} + \int_{t_0}^t \mathbf{\Omega}_{rb}^b(\sigma_1} d\sigma_1 + \int_{t_0}^t \left(\int_{t_0}^{\sigma_1} \mathbf{\Omega}_{rb}^b(\sigma_2} d\sigma_2...

    Is There a Closed-Form Solution for Attitude Update Equations?

    My sub- and super-script is used to denote the frames which we are working on. For all transformation matrix (or direction cosine matrix, here) \mathbf{C}_a^b denotes the rotation/transformation matrix from Frame a to b. And for all angular velocity skew-symmetric matrix \mathbf{\Omega}_{ab}^b...

    Is There a Closed-Form Solution for Attitude Update Equations?

    Hi guys, I am doing navigation mathematics and I met all kinds of references regarding how the attitude update equation should be solved. However, none of the references that I found makes any sense to me. I wonder if someone could enlighten me with this math. The attitude update equation for...
