摘要

David Smith reports on concerns about the future of the current GPS system, a new microwave landing system for Heathrow airport, a plan for improving Irish airspace management and the CAA's preparations for the London Olympics.rnUS government officials are concerned that the quality of the Global Positioning System (GPS) could begin to deteriorate as early as next year. This could result in regular blackouts and failures or even millions of people worldwide being given inaccurate directions. The satellites are overseen by the US Air Force, which has maintained the GPS network since the early 1990s. According to a government study, mismanagement and a lack of investment means that some of the crucial GPS satellites could begin to fail as early as next year.
