Following its April launch, the U.S. Air Force’s Communication/Navigation Outage Forecasting System (C/NOFS) satellite is now gathering data that scientists hope will enable better forecasting of ionospheric interference with radio communications. This interference, known as scintillation, occurs when radio waves traveling through the ionosphere at 50-360 miles altitude become distorted or lost. The phenomenon can cause serious transmission problems for communications or Global Positioning System (GPS) satellites.
