Abstract: A wire clamping system includes a base and an insert. The base includes a first base wall; a second base wall; and a cavity defined by the first base wall and the second base wall. The cavity has a lower portion. The insert is configured to fit within the cavity, and includes a first end shaped to be substantially flush with the cavity; a second end opposite the first end; and at least two passages therethrough. At least two bolts are configured to be received by the second end of the insert and at least two holes positioned in the lower portion of the cavity. Securing the at least two bolts to the at least two holes in the cavity causes the first end of the insert to move towards the lower portion of the cavity.

Abstract: Drift-based rendezvous control system for controlling an operation of a spacecraft to rendezvous the spacecraft to a goal region over a finite time (FT) horizon. The system including accepting data including values of spacecraft states at a specified time period within the FT horizon. A processor at the specified time period selects a set of drift regions corresponding to a desired goal region at a location on an orbit where the target is located at the specified time period. Update a controller having a model of dynamics of the spacecraft with the accepted data. Formulate the set of drift regions as a penalty in a cost function of the updated controller. Generate control commands resulting in a real-time drift-based control policy where upon entering the drift region, the thrusters are turned off in order to minimize an amount of operation of the thrusters while rendezvousing with the desired goal region.

Abstract: Systems and methods controlling an operation of a vehicle in real time to rendezvous the vehicle with a target over a finite time horizon having multiple specified time periods. Select a set of unsafe regions from stored unsafe regions, the set of unsafe regions represents regions of space around the target in which any operation of the PSNO thrusters does not avoid collision with the target, guaranteeing collision trajectories with the target. Formulating the set of unsafe regions as safety constraints, and updating a controller having a model of dynamics of the vehicle with the accepted data. Generating control commands by subjecting the updated controller to the safety constraints to produce a rendezvous trajectory that avoids the set of unsafe regions, guaranteeing an operation of at least the PSNO thrusters, in the event of partial vehicle thruster failure results in a trajectory that does not collide with the target.

Abstract: A system for controlling an operation of a vehicle to rendezvous with a target over a finite time horizon, wherein the vehicle and the target form a multi-object celestial system. A processor to formulate passive unsafe regions as passive safety constraints. The passive unsafe regions represents regions of space around the target guaranteeing collision trajectories with the target, in an event of total thruster failure. Update a controller having a model of dynamics of the vehicle with received data, and subject the updated controller to the passive safety constraints to generate control commands that produce a collision free rendezvous trajectory which avoids unsafe regions for the specified time period, guaranteeing a collision free trajectory with respect to the target in the event of the total vehicle thruster failure, so the vehicle does not collide with the target. Output the control commands to activate or not activate thrusters of the vehicle.

The energy absorbing portion has a first load-bearing web integrally bound to a second load-bearing web. The energy absorbing portion is coiled in a spiral shape in an undeployed configuration. The energy absorbing portion is deployable from the undeployed configuration to a deployed configuration when the first end is pulled away from the second end due to a force exceeding a minimum predetermined force threshold such that at least a portion of the first load-bearing web tears away from at least a portion of the second load-bearing web. The first load-bearing web and the second load-bearing web are integrally bound in the energy absorbing portion by a plurality of binder threads.
