Technical data


The U.S. Air Force has decided to accept the first GPS III satellite even if some of its components may be flawed. The programme's latest setback may affect a decision on whether to open the final 22 satellites to competition from Lockheed rivals Boeing Co. and Northrop Grumman Corp.

The mistake by subcontractor Harris Corp. forced another delay in the delivery of the first of 32 planned GPS III satellites. The parts in question are ceramic capacitors.
