The Galileo ionospheric model unveiled : A new step towards better performance

Today Galileo, the global satellite navigation programme of the European Union, has published a detailed description of the model used to compensate for the errors arising from interference when navigation signals broadcast by Galileo and other global satellite navigation systems such as GPS pass through the ionosphere.
 
This model is a result of years of intensive research efforts to improve the modelling solutions used for classical telecommunication services. The algorithms defined in this model can be built into receiver equipment such as in-car navigation systems to enable them to reach extremely high levels of accuracy globally when using single frequency services, even during the peaks solar activity during the periodic 11-year solar cycle when signals are subject to the most interference. 
 
Extensive testing has confirmed the quality of the model which has recently been recommended at international level for broader adoption by other constellation providers around the world.
