The solar wind plays havoc with GNSS ground and space segments – destroying electrical transformers and the electronic systems on satellites.
In fact, space weather is the single largest contributor to single-frequency GPS errors and also to differential GPS.2. And right now, we have only three years until the next Solar Max.

Block IIR-M satellite. Lockheed Martin photo.Signal anomalies characterized by the U.S. Air Force as “out of family” transmissions will keep the latest GPS satellite from being declared healthy for months, if ever.
The report on space vehicle number (SVN) 49 by the GPS Wing’s chief engineer, Lt. Col. David Goldstein to the European Navigation Conference in Naples, Italy, on May 4 mixed bad news with glad.
Also known as Block IIR-20(M), the spacecraft carries the demonstration payload for the new civil GPS L5 signal. The March 24 launch probably represented the last chance to meet an International Telecommunications Union (ITU) deadline for securing primary rights to use of the RF band by GPS.

In his April 27 speech to the National Academy of Sciences (NAS) annual meeting, President Barack Obama twice singled out the Global Positioning System as an example of the need for renewing the U.S. commitment to basic scientific research and education.
“The calculations of today’s GPS satellites are based on the equations that Einstein put to paper more than a century ago,” Obama said, having noted that “no one can predict what new applications will be born of basic research. . . .”
