GPS IIF Detector Software Needs Upgrade

Aviation Week and Space Technology:

 

The first Boeing-built GPS IIF satellite in orbit will require software fixes to reduce degradation in the cross-links for its nuclear-detection payload, says Lt. Gen. Tom Sheridan, U.S. Air Force program executive officer for space.

 

Designated SVN-62 by the Air Force, the satellite was launched May 27 and accepted into operation last week, having passed its navigation systems testing. The best-known task for the GPS constellation of 31 spacecraft is to provide navigation, positioning and timing information for more than 1 billion military and civilian users.

 

But the network also carries detectors to warn of a nuclear blast; this is the system suffering the crosslinks degradation, Sheridan says.
