New Air Force Satellites Launched To Improve GPS (techcrunch.com)

AmiMoJo writes: This morning, the United Launch Alliance (ULA) successfully launched a Boeing-built satellite into orbit as part of the U.S. Air Force's Global Positioning System (GPS). This $131 million satellite was the final addition to the Air Force's most recent 12-satellite GPS series, known as the Block IIF satellites. The GPS Block IIF satellites were launched to improve the accuracy of GPS. Before the Block IIF series, the accuracy of GPS could be off by 1 meter. With the new Block IIF satellites in place that error is down to 42 centimeters.

    RTK GPS is accurate to within 1-2 cm lat/long and typically 2-3 cm alt. For now that is about the best accuracy a civilian can get.
