Smartphone data could lead to improved GPS accuracy through ionosphere maps

Analyze This: An ionosphere map from smartphone data may help improve GPS

Smartphones are helping chart an erratic region of Earth’s atmosphere that can mess with navigation systems and other tech. That region is the ionosphere — a sea of charged particles on the edge of outer space. There, the sun’s radiation cooks gases in the air. This rips electrons off neutral atoms and molecules, creating free-roaming charged particles. Levels of these charged particles shift with changing sunlight and solar activity. So the ion…
