During my work of space vehicle orbit determination, I have been confronted with a difficulty that hasn't been solved until now. When calculating the transition matrix that translate the process noises to the state parameters of position and velocity,how can I work out the partial derivatives of the process noise with respect to the position and the velocity parameters?May I take the atmospheric drag model as the process noise explicit expression,if I take air drag acceleration as a process noise? WAITING for your helpful answer.
