| description | In this paper, the dynamics of the relative motion problem in a perturbed orbital environment are exploited based on Gauss’ and Cowell’s variational equations.
The inertial coordinate frame and relative coordinate frame (Hill frame) are studied to describe the relative motion. A linear high fidelity model is developed
to describe the relative motion. This model takes into account primary gravitational and atmospheric drag perturbations. In addition, this model is used in the
design of a control, guidance, and navigation system of a chaser vehicle to approach towards and to depart form a target vehicle in proximity operations. Relative
navigation uses an extended Kalman filter based on this relative model to estimate the relative position and velocity of the chaser vehicle with respect to
the target vehicle. This filter uses the range and angle measurements of the target relative to the chaser from a simulated LIDAR system. The corresponding measurement models, process noise matrix, and other filter parameters are provided. Numerical simulations are performed to assess the precision of this model with respect to the full nonlinear model. The analyses include the navigation errors and trajectory dispersions. |
