GPS to Receive $8 Billion Upgrade
Friday, May 28, 2010 at 7:55AM
Boeing’s Space and Intelligence Systems and Lockheed Martin are constructing 30 new satellites to be place between the 24 GPS satellites already orbiting approximately 11,000 miles above the surface of the Earth. The new satellites will allow for six spare satellites to be available if needed and will triple the signals available for commercial use. The equipment on the satellites will include more accurate atomic clocks able to keep time to a fraction of a billionth of a second.
The upgraded system will significantly increase the accuracy, allowing a location to be pinpointed to within just a couple of feet instead of the current +/-20 feet margin of error. It will also make the system faster, and there will be provision to prevent disruptions such as accidental jamming of GPS signals.
