Satellite to Increase Accuracy of GPS Signals Is Launched
A rocket lifted off early Sunday, carrying into orbit a satellite designed to increase the accuracy of Global Positioning System signals for military and civilian users.
The satellite will replace an older model that is running low on power, according to Air Force Col. Allen Ballenger, system program director for the NAVSTAR GPS Joint Program Office.
The $45-million satellite has a life expectancy of about 10 years and is expected to be operational in 25 days or less. The Air Force pegged the mission cost at roughly $100 million, including the satellite, the rocket and launch services.
The launch had been delayed several times because of problems with the satellite, built by Lockheed Martin, and the Boeing Delta II rocket.
Components on the satellite were replaced after problems were discovered on a satellite already in orbit. Two of the rocket’s nine solid-rocket boosters were replaced after problems were discovered this year.
