IONOLAB-TEC service is a JAVA based application which uses the Reg-Est algorithm—a novel TEC estimation algorithm providing the user with high resolution (30 sec) and robust TEC estimates. 

IONOLAB-TEC provides TEC estimates in graphical form or in Excel files with 2.5 min time resolution for faster processing. You may estimate TEC using pseudorange only or carrier phase corrected TEC.

IONOLAB-TEC uses CODE DCB biases and satellite ephemeris data where available. Otherwise, IONOLAB-TEC estimates the receiver bias with Scaling TEC on IONEX maps.

If you need 30 s resolution or for a zoomed-in time period within 24 h, or if you want to report a suspicious TEC estimate: please contact.
