Northrop Grumman solar arrays power OneSat satcoms
Airbus Defence and Space has awarded Northrop Grumman a contract for the design, development and production of 24 ship sets of solar arrays for its OneSat satellite product line.
The solar arrays are a 20kW-class system that deploys over 18 meters in order to provide energy to the satellite, says Northrop. They will power the OneSat communication satellites in geosynchronous orbit.
The solar array technology features Northrop Grumman’s Compact Telescoping Array (CTA) design, which uses a telescoping boom system to deploy an “accordion-folded” flexible solar array blanket. The design is aimed at missions that require extremely compact stowage volume for spacecraft launch while remaining lightweight. Northrop Grumman states that CTA creates enough space to allow three full spacecraft to be launched on a single rocket.
