Levels of Spacecraft Autonomy

摘要

As autonomous systems are being developed in multiple industries it has been recognized that a phased approach is needed both for technical development and user acceptance. Partially in response, the automotive and aircraft industries have published five or six Levels of Autonomy in an attempt to broadly characterize the amount of autonomy technology that is present in any particular vehicle. We have developed a similar six Levels of Spacecraft Autonomy for similar purposes. Here, we propose extending these ideas to spacecraft constellations, clusters, swarms, ground stations for spacecraft, and strategic collaboration among space and ground assets. We intend these levels of autonomy to be used to characterize and describe high-level capabilities for any given satellite for education and communication with lawmakers, government officials, and the general public. All of the proposed levels mimic those of the automotive and aircraft levels in an attempt to maintain consistency and a common understanding with our intended audiences.
