The ESS [Extendible Support Structure] assembly consists of an Electronic Control Unit(ECU), a drive mechanism assembly, and two identical independently-deployable wing assemblies. Each wing includes a deployment mechanism, a truss structure supporting two SAR antenna panels, and a variety of sensors. During launch, the ESS is supported by the SAR antenna panels which are restrained against the Spacecraft Support Structure by Antenna Tie-Down at six locations per wing.

CONT

Hexapod is a support facility to be mounted on an EXPA of the ISS. The facility will be used for the Stratospheric Aerosol and Gas Experiment III(SAGE III). The facility has a bottom plate and a top plate. The two plates are connected by 6 linear actuators. Hexapod receives the pointing data from SAGE III and the actual base position from the ISS-EXPA. From this data the HEXAPOD control algorithm calculates the next position for each leg. Each linear actuator is driven by a double winding Brushless DC Motor, while the position is monitored by an incremental encoder. To sustain the launch load a launch support structure has been designed, which is released by dedicated electromechanical devices. Hexapod is controlled by a dedicated electronic unit... which interfaces to the Station via the MIL BUS 1553B.

OBS

Hexapod pointing device: term officially approved by the International Space Station official approval Group (ISSOAG).

PMA-2[, ] the second unit was temporarily attached to Unity before launch and provides the initial docking interface for Shuttle missions with ISS [International Space Station]. One end is attached to Unity by a Passive Common Berthing Mechanism, while the other end uses an Androgynous Peripheral Attach System to connect with the Shuttle external airlock and docking system. This unit has a hatch and an 8-inch view port. Attached to the exterior of PMA-2 are MDM [Multiplexer/Demultiplexer] computers, providing early command and control of the Unity node. This allows the Shuttle crew to control the Shuttle-end PMA-2 docking mechanism from the orbiter's aft flight deck. PMA-2 is planned for relocation on a later ISS assembly mission, and further details on activities relating to this unit will be updated when this occurs.

Subject field(s)
  • Spacecraft
CONT

The Extendible Support Structure(ESS) deploys and supports the SAR antenna panels in its mission configuration. The ESS assembly consists of an Electronic Control Unit(ECU), a drive mechanism assembly, and two identical independently-deployable wing assemblies. Each wing includes a deployment mechanism, a truss structure supporting two SAR antenna panels, and a variety of sensors. The ESS subsystem also includes command and telemetry to control and monitor the ESS prior to and during deployment. During launch, the ESS is supported by the SAR antenna panels which are restrained against the Spacecraft Support Structure by Antenna Tie-Downs at six locations per wing. Deployment of the ESS is initiated by a ground command sometime after the release of the antenna tie-downs. Following deployment, the ESS is capable of supporting the SAR antenna panels such that the peak-to-peak deviation due to thermo-elastic distortion is not greater than 1. 1 mm over the entire antenna surface.

OBS
