Abstract
A link system (100) for a spacecraft (10) comprises control and communication circuitry and is configured to communicate with subsystems (12) in the spacecraft (10) independent of an on-board computer (102) and configured to manage communication between the subsystems (12) and external entities (150, 160). The link system (100) is configured to determine that an anomaly has occurred in functionality of the on-board computer (102) and/or at least one subsystem (12). As a consequence of the determination that an anomaly has occurred, the link system (100) initiates a recovery procedure that comprises enabling the external entity (150, 160) to execute recovery actions in relation to the on-board computer (102) and/or at least one subsystem (12).
Claims23
A link system for a spacecraft, the spacecraft comprising:
- a plurality of subsystems interconnected with each other,
- an on-board computer configured to communicate with the subsystems and to at least convey data between the subsystems and the link system, and
- a wireless communication system configured to communicate data between the spacecraft and at least one external entity,
- wherein the link system comprises control and communication circuitry and configured to:
- communicate with the subsystems independent of the on-board computer and configured to manage communication between the subsystems and the external entity via the wireless communication system,
- determine that an anomaly has occurred in functionality of the on-board computer and/or in functionality of at least one subsystem among the plurality of subsystems, and
- as a consequence of the determination that an anomaly has occurred, initiating a recovery procedure that comprises enabling the external entity to perform recovery actions in relation to the on-board computer and/or in relation to at least one subsystem among the plurality of subsystems.
(canceled)
A method performed by a link system for a spacecraft, the spacecraft comprising a plurality of subsystems interconnected with each other, an on-board computer configured to communicate with the subsystems and to at least convey data between the subsystems and the link system, and a wireless communication system configured to communicate data between the spacecraft and at least one external entity, wherein the link system comprises control and communication circuitry that performs the steps of:
- determining that an anomaly has occurred in functionality of the on-board computer and/or in functionality of at least one subsystem among the plurality of subsystems, and
- as a consequence of the determination that an anomaly has occurred, initiating a recovery procedure that comprises enabling the external entity to perform recovery actions in relation to the on-board computer and/or at least one subsystem among the plurality of subsystems.
