IONO4HAS-Home Networks Tests Results Products +Info

Assessing the IONO4HAS model

The IONO4HAS tool performance and quality is evaluated through positioning 22 different rover receivers using different techniques. Rovers are grouped to form networks in dedicated regions (coded by colours):

In Europe: Spanish network , Belgium network, Finnish network and Eastern network.
In South America: Brazilian network.

Yesterday's ionospheric residuals

This test is computed from the yesterday's ionospheric modelling residuals at the rover receivers.

Real-time ionospheric rover solution using the unambiguous STEC residuals

These plots are generated for each rover receiver, depicting the rover solution in blue, and in red the residues for all the other receivers within the same network, used in the IONO4HAS model.
