ISS Science for Everyone

Science Objectives for Everyone
Controlling several remote space assets at once, such as robots aboard the International Space Station, is a difficult and time-consuming task. The Supervision of Autonomous and Teleoperated Satellites - Interact (SATS-Interact) experiment is designed to improve this remote control by allowing one person to supervise a remote team of small satellites working on a common mission.

    Experiment Description

    Research Overview

    • Simultaneous teleoperation of multiple remote space assets is currently a laborious task undertaken by multiple skilled operators who directly translate their actions to commanding remote space assets. This process alternates between periods of direct teleoperation and assessment of its results and progress to mission objective. This process is not efficient and requires substantial effort on the part of human operators resulting in loss of productivity and risk to valuable space resources.


    • Supervision of Autonomous and Teleoperated Satellites (SATS) is a research effort aimed at reducing the complexity of teleoperation of multiple space assets. SATS will develop a user interface and control methodology, called Interact, which will be applied to commanding multiple space resident nanosatellites from the ground overcoming the inefficiencies of direct remote manipulation which is also burdened bu communication delays and blackouts.


    • Efficient visualization of telemetry and innovative command and control interface will simplify teleoperation and enable a continuous dialog between human and artificial team members (space assets) working on a common mission. This will reduce the complexity of current missions relying on remote supervision and coordination of space assets and enable more complex missions supported by capable robotic agents working in teams on a common task under supervision of a just a few human users.

    Description

    Supervision of Autonomous and Teleoperated Satellites (SATS) is a research effort aimed at drastically improving remote operation of space assets by enabling one user to control multiple maneuvering satellites. SATS effort is developing Interact, a command and control user interface, which enables one user to supervise the tasking and monitor the activity of a team of remote nanosatellites working on a common mission.

    Simultaneous teleoperation of multiple remote space assets is currently a laborious task undertaken by multiple skilled operators who directly translate their actions to commanding remote space assets. This process alternates between periods of direct teleoperation and assessment of its results and progress to mission objectives. This process is not efficient and requires substantial effort on the part of human operators resulting in loss of productivity and risk to valuable space resources.

    SATS applies data and information visualization techniques inside an immersive environment to fuse data and telemetry coming from multiple remote sensors to drastically improve situational awareness of the human operators and increase information absorption towards more efficient decision-making . The interaction between human and robotic team members is implemented as a spatial dialog where multimodal interaction techniques are used to convey tasking intent to implement human-in-the-loop and human-on-the-loop command and control frameworks.

    Applications

    Space Applications

    A new user interface and control system called Interact allows ground-based users to operate space-based assets more efficiently. The software provides a direct interface that can overcome communications delays and blackouts. Supervision of several assets working as a team provides a more efficient way to assemble spacecraft, refuel or repair satellites, or conduct emergency repairs on the International Space Station.
     

    Earth Applications

    Research under the SATS program could apply to remote control of various autonomous robots, including those working underwater, in hazardous conditions and in industrial settings. The Interact command software could lead to more effective human supervision of these remote-controlled robots, which could improve efficiency and safety.

    Operations

    Operational Requirements

    • 6 SPHERES Test Sessions with 3 satellites


    • Sessions 1, 2, 3: On-board interaction -


    • Session 1: Check out new GUI upgrades


    • Session 1 to Session 2: 2 to 3 weeks later


    • Session 2 to Session 3: 6 to 8 weeks later


    • Sessions 4, 5, 6: real-time ISS-ground command and data handling


    • Session 4: Check out new real-time C&DH capability


    • Session 4 to Session 5: 2 to 3 weeks later


    • Session 5 to Session 5: 4 to 8 weeks later


    • Usage of regular consumables (CO2 & Batteries) during test sessions


    • SPHERES GUI Upgrades


    • GUI Executable Upgrades


    • One time for "on-board interaction"


    • One time for "real-time C&DH"


    • Matlab installed for use aboard ISS


    • SPHERES Program File (SPF) < 1MB (standard SPHERES procedures)
    • Downlink:


    • Video of the tests (2 Camera vies, as per standard SPHERES procedures)


    • SPHERES Data & Log Files (SDF, SGF, SLF) (standard SPHERES procedures)

    Operational Protocols

    Interact will follow the standard SPHERES procedures with the following differences:
    On-board interactions
     

    • 1.001 Setup: no changes


    • 2.001 Run Tests:


    • Will follow the standard procedures; in the "Test Overview" the crew will be instructed to interact more with the satellite and observe the animation tools on the screen. These tests will be designed to follow all the standard SPHERES procedures.


    • The crew "interactions" will use keyboard "run-time" commands, which have been exercised by the SPHERES team in the past, therefore no new procedures or crew actions will need to take place.


    • 2.002 Consumables: no changes


    • 2.003 Shutdown: no changes


    • "Real-time command and control"


    • 1.001 Setup:


    • May need a step to confirm real-time data availability


    • 2.001 Run Tests:


    • Follow standard procedures; once a test is started the crew will "observe" the satellites as they do for "autonomous" tests, except in this case the satellites will move based on real-time commands from the ground. As with autonomous tests, the crew will have the ability to stop the test at any time.


    • 2.002 Consumables: no changes


    • 2.003 Shutdown: no changes
