The GPS L1 and L2 signals propagate through the ionosphere at different speeds due to the dispersive nature of the ionospheric plasma The accumulated delay between the two signals is

How do ionospheric irregularities affect satellite communication and navigation?

Ionospheric irregularities can affect satellite communication and navigation by causing scintillations of radio signals. The scintillations are routinely measured using ground-based networks of receivers. This study presents observations of ionospheric irregularities by Langmuir probes on the Swarm satellites.

Can we predict the ionospheric propagation parameters needed in planning satellite systems?

c)that experimental data have been presented and/or modelling methods have been developed that allow the prediction of the ionospheric propagation parameters needed in planning satellite systems;

What are the most common ionospheric measurements made using satellite beacons?

The most common ionospheric measurements made using satellite beacons are (1) Faraday rotation, (2) Delay due the ionospheric line of sight electron content, and (3) Signal scintillation. MEASURING FARADAY ROTATION

How does ionospheric scintillation affect GPS?

In the equatorial region, deep amplitude fading in global positioning system (GPS) signals frequently occurs during the strong ionospheric scintillation, it can lead to the loss of lock in GPS carrier tracking loops, and result in increased positioning error and even navigation interruption.
