Spaceflight Now | Delta Launch Report | GPS modernization begins with Delta rocket launch

A new modern GPS has been launched-the first of many to replace the older satellites. It is backwards compatible with most older receivers. I'm hoping the accuracy of my GPSr will improve. It should take a while for an entire constellation of new satellites to be put in place, but this is a start.

"The advancements for the military will provide warfighters with a more robust jam-resistant signal and enable better targeting of GPS-guided weapons in hostile environments, while the new civilian signal removes navigation errors caused by the Earth's ionosphere.

"I think this is a pretty huge step. We have essentially been operating on the original-design signals of GPS for over a decade, and this is going to be the first time we are actually adding new signals from space," said Col. Allan Ballenger, GPS system program director at the Space and Missile Systems Center. "
