Teledesic, the satellite communications company backed by Bill Gates and Craig McCaw, has signed up Lockheed Martin to launch the majority of its satellites into space.
The aerospace giant will use two heavy lift launch vehicles, the Proton M and the Atlas V, to send the satellites into orbit.
Teledesic also said it had finalised the design of the system's communications network with its prime contractor, Motorola. Last year, Motorola dramatically ditched a $12.9 billion plan to develop Celestri, its own satellite venture, to take a stake in Teledesic.
As part of the deal, Motorola will pay Teledesic $150 million in cash, but will receive an initial $250 million for its contract work.
