Product Description: 2-D product showing the recent conditions of ionospheric Total Electron Content that impact GNSS-derived position accuracy. Vertical TEC and slant-path values of the line-of-sight electron content to the GPS satellites in view are given. This ionospheric product is designed to estimate the signal delay for single and dual frequency GNSS applications. Target Users: Product users include industries relying on high-accuracy GNSS positioning, such as airlines, agriculture, surveying, construction, and drilling. |
