However, the rigorous mathematical proof of stability of a further detailed coupled controller is currently ongoing research and therefore intended as future work. This process was studied, however, for set values of tf, providing a means of determining the fuel optimal trajectory by sweeping through tf values. Additionally, this method for computing the total ΔV prevents double-counting should any acceleration terms act in opposite directions. Additionally, the Chaser is assumed to have a controller which will enable it to follow the desired trajectory. Additionally, though both the linear and logarithmic spacing time steps averaged to 1.8 s (180 s trajectory broken into 100 time steps), the SD of the time steps is 1.7 s for the logarithmic spacing and 2.8 s for the linear spacing. Consequently, the linear spacing tasked the solver with finding the time steps between points that were uniformly distributed over the desired radial span. 1 through Eq. 6. These equations describe the velocity profile that the Chaser satellite must follow if it is to remain along the docking axis of the Target, which is taken to be rotating at ωTAR.

Should thrusters be used instead, an additional fuel penalty would be necessary to account for the need to maintain the appropriate docking attitude. Several reference frames are used to describe the motion of both the Target and Chaser: those of the Target (TAR), docking port (UDP), inertial (INT), and Chaser (CHA). With this set of initial conditions, the Chaser begins its approach by adjusting its trajectory from one that is orthogonal to the docking axis to an accelerated trajectory inward along the docking axis. That is, the force and torque in an inverse direction reacts on the end-effector of the chaser. For this analysis, the Chaser is assumed to have the ability to fire its thrusters at any magnitude as required.

The accelerated trajectory requires the chaser’s thrusters to generate four types of acceleration. The constraint of maintaining synchronicity throughout the terminal approach to the rotating Target forces the Chaser to follow an accelerated profile, i.e., the Chaser must use its thrusters throughout the maneuver. болка в гърба и тежест в гърдите . The Chaser maintains synchronicity along its approach by keeping its axis system aligned along the docking axis. The computation of the velocity of the Chaser satellite at each time step enables both the propagation of the Chaser’s position with time and the determination of the change in velocity at each time step necessary to maintain synchronicity. Solving for optimal dt steps between logarithmically spaced radial points, therefore, mitigates this effect without the need to increase the number of time steps (and the associated computational cost) and enables trajectory generation for range of tumble types.

Equation 4 determines the rate of change of the Target’s quaternion resulting from its tumble. In order to determine fuel optimal trajectories, a process must be created to compute the fuel requirements for various tumble types. The solver can, therefore, be used to determine fuel optimal trajectories for the Chaser satellite to follow as it approaches the Target. The number of time steps is taken as 100 for this paper to balance the computational requirement and the accuracy of the resulting optimal trajectory, since a forward propagation using Euler’s equations is used to determine the states of the Chaser and Target over time. Equation (34) can be used to compute the drag coefficient CD of a sphere. 2. Fit a parameterized approximation to the fuel optimal trajectory. Try fitting different curve expressions to the fuel optimal radial trajectory. This cost is considered to be small because of the ability of the Chaser to change its orientation through rotating its inertia over the same duration as the whole mass must move in the synchronous approach.
