(Reuters) - U.S. Deputy Defense Secretary Robert Work on Tuesday said he was still not confident about completion of a long-delayed, over-budget ground-based system being developed by Raytheon Co to control new GPS satellites built by Lockheed Martin Corp. "Before I say I'm confident that we've turned the corner, I'm going to have to see more data," Work told reporters aboard a military aircraft en route to Buckley Air Force Base in Aurora, Colorado
