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. |
R1 (Minor) Radio Blackout Impacts
HF Radio: Weak or minor degradation of HF radio communication on sunlit side, occasional loss of radio contact.
Navigation: Low-frequency navigation signals degraded for brief intervals.
