Abstract: System and methods for managing boundaries of a vehicle being guided toward a target are provided. In some aspects, a system includes a first gate module configured to receive primary positional information of the vehicle and secondary positional information of the vehicle, to compare the primary positional information with the secondary positional information, and to generate a first pass indicator or a first fail indicator based on the comparison. The system also includes a first boundary module configured to confine navigation of the vehicle to within one of a plurality of termination boundaries based on which of the first pass indicator and the first fail indicator is generated. Each of the plurality of termination boundaries is confined within a range boundary of the vehicle and offset from the range boundary at a different magnitude.

Abstract: System and methods for managing targets of a vehicle is provided. In some aspects, a system may include a boundary check module configured to receive boundary information from a flight safety system. The boundary information comprises a selected termination boundary of a plurality of termination boundaries confining navigation of the vehicle. Each of the plurality of termination boundaries is associated with a target of a plurality of targets of the vehicle. The system may further include a target modification module configured to select the target associated with the selected termination boundary, and a target guidance module configured to provide the selected target to a guidance and control system of the vehicle.

Abstract: A system for reducing plasma induced communication disruption utilizes an electrophilic gas injectant, bent reentry vehicle nose shaping and a number of flaps configured to provide 3-axis steering capability. Injecting electrophilic gas injectant into plasma accomplishes reduction of plasma induced communication disruption by removing free electrons in the plasma which causes the communication disruption. For reentry vehicles, a bent biconic nose also reduces plasma effect during reentry. By combining electrophilic gas injection and bent nose shaping, the system reduces and/or eliminates plasma induced communication disruption, such as, GPS communication blackout, for a reentry vehicle during reentry. Furthermore, the 3-axis steering capability renders the reentry vehicle more maneuverable. Performance of the reentry vehicle during reentry, such as, target accuracy, is thus improved.
