Detailed Description

Structure container for the quaternionic orbital elements, which is made of four quaternionic parameters: \( [q¹, q², q³, q⁴] \).

Note

For more information on the quaternionic orbital elements, refer to "Alternative Set of Nonsingular Quaternionic Orbital Elements", by J. Roa and J. Kasdin, Journal of Guidance, Control, and Dynamics, Vol. 40, No. 11, November 2017.
