China has disclosed that it intends to build a GPS-like global navigation system. Named Compass, the $2 billion system would have 30 satellites in medium earth orbits similar to the current GPS. Five additional satellites will provide WAAS-like and other functions, with a forecast 10-meter accuracy free to all users. Western experts predict likely operation between 2015 and 2020.
While it may be hard to believe that the global positioning system (GPS) is already more than a quarter century old, it may be equally difficult to imagine that by 2020 there will be more than 100 navigation satellites crisscrossing in outer space, high above us. Yet the first is true and, barring unforeseen eventualities, the second will also be true.
Since it was disclosed late last month that President Bush has directed the Department of Defense to draw up plans for temporarily disabling the U.S. network of GPS satellites during a national crisis to prevent terrorists from using the technology, operators have been seeking more details and clarification of the policy. How U.S. policy would apply to Galileo, Europe’s planned GPS network, is unknown.
The Aeronautical Repair Station Association (ARSA) is conducting an industry-wide survey to quantify the effect of aviation maintenance on the economy. The confidential, Web-based survey is open to ARSA members and non-members.
They say that politics makes for strange bedfellows. So, it seems, does loran, which has recently been recognized by four quite disparate groups: the U.S. Congress, the government of France, the telecommunications industry and the National Air Traffic Controllers Association (NATCA). But in Washington, inter-agency budget struggles cloud further progress with the system.
Inmarsat announced it has been selected to manage the company that will look after Galileo’s global network operations, including performance monitoring and operations security.
