Docking a spacecraft
Approach the station, match orientation and settle into the docking collar. Automatic guidance uses the same limited thrusters as your manual commands.
The model and its limits
Linear Hill relative-orbit dynamics, six-axis RCS commands and finite propellant. Capture requires low relative speed, small offset and attitude error; station contact uses a simplified response.
Equations used in the module
Equations x_ddot = 3 n² x + 2 n z_dot + a_x; y_ddot = -n² y + a_y; z_ddot = -2 n x_dot + a_z; dm/dt = -F / (Isp g0)
