The Pentagon has issued $16 million contracts to Boeing and Lockheed Martin to study a third generation of GPS navigation systems that could come into use after 2010. A primary concern is cost. Just about everything military (ships, bombs, missiles, planes, tanks) uses GPS and that means tens of thousands of GPS receivers will be purchased. That would mean that every $100 of extra cost would translate into millions of dollars in extra expenses.--Stephen V Cole
