The German Aerospace Center (DLR) has tracked and recorded the first operational L5 GPS signal as transmitted by the first GPS Block IIF satellite launched on May 27. The accompanying spectral image of the signal was received at about 15:10 UTC (GMT) today (June 17, 2010).

With transmissions centered at 1176.45 MHz, GPS L5 lies in a protected ("safety of life") aeronautical radionavigation system (ARNS) band. The U.S. Air Force announced earlier that it will broadcast the L5 signal "intermittently" during a testing period.
