Total Electron Content

Australian region Total Electron Content map

Product Description

2D map showing near real-time ionospheric Total Electron Content (TEC) conditions over the Australian region. Map produced by combining regional GNSS data with the IRI-2007 ionospheric model driven by real-time foF2 observations from IPS ionosondes distributed throughout the region. The ionosphere is modelled as a thin shell at a fixed height of 400km. Slant delay from GNSS satellite to GNSS receiver can be estimated from this map, for ionospheric correction.

Target Users

Include industries relying on high-accuracy GNSS positioning: agriculture, surveying, construction, drilling.

Data Source

Ground-based dual-frequency GNSS receivers and ionosondes
