Don't count on your navigation unit seeing a sudden improvement anytime soon, but Raytheon has announced that it's landed an massive $886 million contract from the U.S. Air Force to develop a new element of GPS called the advanced control segment (or OCX, somehow). Once complete, that promises to not only provide a range of enhancements for military GPS use (including anti-jam capabilities and improved security), but improved accuracy and reliability for civil GPS users as well. Details are otherwise a bit light, and this contract only represents the first of two development blocks, but it looks like GLONASS and Galileo may have to step up their game a bit further if they want to stay competitive in the great sat-nav race.
