next-generation Global Positioning System satellite begun testing

New GPS signal for civil users

The next-generation Global Positioning System satellite launched two weeks ago has begun testing the new civilian navigation signal debuting operationally on this spacecraft.
The GPS 2F-1 craft was successfully delivered into an orbit 11,000 nautical miles above the planet May 27 by a United Launch Alliance Delta 4 rocket.
The Space and Missile Systems Center’s Global Positioning Systems Wing says test transmissions of the L5 signal started June 5.

This signal will be broadcast from all future GPS satellites as part of the Air Force’s efforts to upgrade and expand the capabilities from the navigation system.
The L5 signal is a key element of efforts to modernize the GPS constellation for civil users…
All 12 satellites in the new Block 2F series of GPS satellites to be deployed in the coming years will support the L5 signal.
