Ionosphere total electron content (TEC) map

Understand where potential GNSS signal interference may be more prevalent.

Fact 1

TEC is the number of free electrons between two points, such as the receiver and satellite.

Fact 2

Affected by solar activity, the more TEC, the longer the period of GNSS interference.

Ionosphere scintillation map

Identify where atmospheric irregularities are strongest and interfering with GNSS signal delivery.

Fact 1

Space weather, such as sunspots, cause distortions in the Earth's upper atmosphere.

Fact 2

These fluctuations can result in GNSS signal errors.
