OneWeb, founded in 2014 by entrepreneur Greg Wyler, planned to launch 650 satellites into low earth orbit to provide universal internet but was locked in a constant struggle to raise funds.
An early entrant in a sector with challengers including Elon Musk's SpaceX, the startup's spectrum and rights will become increasingly valuable in the long run as the space business heats up, one of the sources said.
Other parties, including those targeting the spectrum, are also circling, sources have said. Canada's Telesat is interested, one of the sources said.
OneWeb's previous investors include chip supplier Qualcomm Inc and Airbus, with which it ran a satellite factory based in Florida.
