Near Real-Time TEC Maps
Welcome to the Transionospheric Radio Link - Near-real-time TEC maps service
Overview
The service "Transionospheric Radio Link - Near-real-time TEC maps" aims to provide maps of the Total Electron Content (TEC) no more than 5 minutes after observation (near-real-time). Supplementary materials are measurements from ionosondes (URSI parameters), height of maximum electron density in the F2 layer (hmF2). The Smoothed Sunspot Number (SSN) and the solar flux density from the entire solar disk at 10.7 cm (F10.7) are solar parameters contributing to this service. They are proportional to the level of ionisation in the ionosphere and therefore commonly used for TEC models.
This service addresses the needs of trans-ionospheric radio links users. This includes primarily Global Navigation Satellite System (GNSS) users and service providers, using GNSS single frequency services (e.g. EGNOS users and typical GNSS mass market users), GNSS multi-frequency services (e.g. aeronautical systems, geodetic users, Real-Time Kinematik) and users of satellite data communications (e.g. Search and Rescue, Air Traffic, etc.) and other space-based services affected by the ionosphere (e.g. radars, altimetry, radioastronomy, etc.).

User Manual
The Total Electron Content (TEC) is defined as the integral of the electron density along the ray path between satellite and receiver. Thus, TEC provides the number of electrons per square metre. The most frequently used unit is 1TECU = 1x1016 electrons / m2.
