Two air-bearing motion dynamics testbeds enable experiments of spacecraft maneuver dynamics and contact dynamics.
Integrated Flat Floor
- 5.9 m x 3.6 m acrylic flat floor within the frames of the Maneuver Kinematics Simulator
- Enables coordinated use of gantry mechanism with
air-bearing vehicles for kinematics/dynamics experiments such as robotic capture of debris objects
High-Precision Air-Bearing Table
- 3.6 m x 1.8 m tempered glass plate on optical bench with pneumatic vibration isolators
- Enables experiments in contact dynamics, spacecraft controls, formation flight, docking/capture, etc.
- Planar air-bearing vehicles (ABV) for formation flight and docking / capture experiments
- Propulsion: custom thrusters using compressed N2
- Attitude control: Thrusters or custom reaction wheels
- On-board computer: Intel i5
- Endurance: ~20 minutes
- Aluminum frame allows easy attachment of capture tools, docking interfaces, sensors, robot manipulators, etc.
- Hilio D12 LED high-intensity light panel used to simulate orbital lighting conditions
- Light panel is daylight balanced
- Equivalent to 2000 W incandescent light
- Intensity sufficient to oversaturate dynamic range of cameras, produce stark light/shadow differences, and blind laser range finders.
- Lens inserts used to change the beam angle between 15° and 60°.
- 12-camera OptiTrack Prime 17W system tracks objects within the ORION Lab with sub-millimeter and sub-degree accuracy
- Objects are defined by four infrared reflectors
- Real-time streaming of tracking data on the lab network
- Used in closed-loop control of the Maneuver Kinematics Simulator
- For formation flight and docking experiments, OptiTrack can be used as stand-in for relative navigation sensors
- For sensor testing, the OptiTrack data serves as ground truth
- ORION Control Room has a control station for the testbed and multiple workstations for equipment operators and test engineers
- Teleoperation console equipped with multiple input devices to support experiments in the teleoperation of ground, air, and space robots and vehicles.
- Operator at teleoperation console do not have direct sight of the testbed and all video and telemetry channels can feature artificial time delays.
- Use of multiple swarm satellites equipped with 3D cameras (stereoscopic / time-of-flight) to produce point-cloud model of resident space object
- Point cloud will be processed to:
- Characterize target motion (tumbling axis and rates)
- Map geometry of target
- Identify surface features for capture, servicing, neutralization, etc.
- Capability enables swarms of small satellites to inspect, characterize, safely approach and engage non-cooperative resident space object
- Applications:
- On-orbit servicing
- Debris removal
- Inspection
- Protection and defense
