Quality Assessment of Ionospheric Correction

Welcome to the Transionospheric Radio Link - Quality Assessment of Ionospheric Correction service

Overview

The service "Transionospheric Radio Link - Quality Assessment of Ionospheric Correction" aims to provide information on whether standard corrections to GNSS signal are applicable, including for the TEC core products a-posteriori and estimated parameters and near-real-time alarms to indicate the level of degradation of ionospheric correction models with respect to the actual state of the ionosphere. This latter assessment shall be established by considering the update rate for the different service users among the following:

  • Users of GNSS Single frequency services with average accuracy, no integrity (e.g. typical GNSS mass market user)
  • Users of GNSS Single frequency services with average accuracy, using integrity (e.g. EGNOS user)
  • Users or multi-frequency GNSS systems with very high accuracy (e.g. GNSS geodetic users, RTK).

This service is implemented through a combination of products, tools and alerts which can be found through the following sections along with expert support provided by the teams constituting the SWE Network. Should you require further guidance in the use of this service, or have specific questions about any aspects of the service presented here, don’t hesitate to contact the Helpdesk.

User Manual

Many applications use ionospheric correction models to estimate the ionospheric dependencies. The accuracy of this estimation depends on the actual state of the ionosphere. Degradation of the accuracy occurs during perturbed conditions, e.g. ionospheric storms or scintillations. Therefore, this service provides TEC core products a-posteriori and estimated parameters and near-real-time alarms to indicate the level of degradation of ionospheric correction models with respect to the actual state of the ionosphere.
