ORUs are parts of the main systems and subsystems of the external elements of the ISS, none are intended to be installed inside the pressurised modules. Examples of ORUs are: pumps, storage tanks, controller boxes, antennas, and battery units. Such units are replaced either by astronauts during EVA or by the Dextre (SPDM) robotic arm.

2019年8月30日 · The complex Electric Power System (EPS) onboard the International Space Station (ISS) provides all the power vital for the continuous, reliable operation of the spacecraft. NASA Glenn Research Center’s Space Operations Division is leading the sustaining engineering and subsystem integration of EPS hardware.

External payloads will be interacting with ISS robotic systems in one way or another. Robots on ISS provide a lot of flexibility, but that also brings increased options and complexity that must be taken into account. The purpose of this presentation is to provide an overview of the robotic

ORU provides power to the OGA electrolysis cell stack. The PSM ORU provides a variable range of 10-46.9 amps of current to the OGA cell stack during Process mode and 1.0 amps (A) during Standby mode (2% oxygen production rate). The ISS OGA was originally designed to generate oxygen at a nominal rate

On the international space station (ISS), power quality specifications are designed to ensure system stability and operability of electronic hardware. System-level test data and model analysis results are verified against the power quality specifications.

2002年12月11日 · This handbook provides guidance on selecting the appropriate ORU items to ensure that a flight system is supportable on-orbit. It addresses: • The need for an ORU selection process. • The ORU selection as an integral function of systems engineering and the supportability engineering processes.

part of the International Space Station (ISS) Environ-mental Control and Life Support (ECLS) system. The CDRA provides carbon dioxide (C02) removal from the ISS on-orbit modules. Currently, the CDRA is the sec-ondary removal system on the ISS, with the primary sys-tem being the Russian Vozdukh. Within the CDRA are
