Space Systems/Loral Power Equipment for Space Station to be Launched On Upcoming Space Shuttle Flight.Business/Aerospace Editors NEW YORK--(BUSINESS WIRE)--Nov. 20, 2000 Batteries and power electronics to be launched on Space Station Flight 4A aboard Space Shuttle Endeavor When the Space Shuttle Endeavor is launched later this month on Space Station Flight 4A, on board will be a set of powerful batteries and power electronics built by Space Systems/Loral (SS/L SS/L Space Systems/Loral (Palo Alto, CA) SS/L Space Station/Loral ), the first such flight set for the U.S. photovoltaic module which is to be delivered for installation on the International Space Station. SS/L's equipment, built under a contract with Rocketdyne Propulsion & Power Division of the Boeing Company, will be used to store energy and regulate electrical power on the Space Station. SS/L will provide a total of 48 Battery Orbital Replacement Units (ORU ORU Oral Roberts University (Tulsa, Oklahoma) ORU Organized Research Unit(s) ORU Orbital Replacement Unit ORu Old Russian (linguistics) ORU Orbital Replaceable Unit ), 24 Battery Charge Discharge Units (BCDU BCDU Battery Charge/Discharge Unit BCDU Bomber Command Development Unit (Royal Air Force) BCDU Bus Control Display Unit BCDU Battery Charge Discharge Unit ), and eight Sequential Shunt Units (SSU SSU Small Subunit SSU Sonoma State University SSU Savannah State University (Savannah, Georgia) SSU Shawnee State University (Ohio) SSU Salisbury State University ) for the final on-orbit configuration of the Space Station. In its orbit around the earth, the Space Station encounters periods of sunlight and solar eclipse. During sunlight operation, the SSU regulates the electrical power from the solar panels. Some of the power is used by each BCDU to charge two Battery ORUs, with the rest of the power available for other uses on the Space Station. The nickel-hydrogen batteries store electrical energy for use during the solar eclipse period encountered during each orbit. The BCDU also conditions and regulates the battery discharge power for use by the Space Station during the solar eclipse period. The launch will be the first delivery of SS/L's Battery ORUs and BCDUs to the International Space Station, scheduled for launch on the Endeavor (Mission STS-97) on November 30. This mission will carry the P6 Integrated Truss Structure The Integrated Truss Structure forms the backbone of the International Space Station, with mountings for unpressurized logistics carriers, radiators, solar arrays, and other equipment. , consisting of 12 Battery ORUs, six BCDUs, and two Sequential Shunt Units (SSUs) manufactured by SS/L. An earlier SS/L-built SSU was carried to the Space Station on May 27, 1999. Space Systems/Loral is a premier designer, manufacturer, and integrator of powerful geostationary Aligned with the earth. Refers to satellites (GEOs) that travel at the same rotational speed as the earth (they are geosynchronous) and are always the same distance from the earth. See GEO. satellites and satellite systems. SS/L also provides a range of related services, including mission control operations and procurement of launch services. Based in Palo Alto, California “Palo Alto” redirects here.
