I understand that for ground based gps receivers, the TEC is computed along the line-of-sight between the receiver itself and the GPS satellite (known as Slant TEC or STEC). Vertical TEC (or VTEC) is obtained using STEC, however it gives readings above the subionospheric point.
I have 2 questions with reference to the above paragraph:
1) For the STEC measurements, which geographic location does it correspond to? Is it the receiver's location?
2) I'm assuming VTEC correspond to the geographic location of the subionospheric point (and not the receiver). If I am right on my assumption, how can I determine this point?
Next, I have a question regarding TEC derived from satellite-based receivers.
3) For data involving formosat/cosmic radio occultations yielding TEC, which is the point on earth that the data correspond to?
Thank you in advance for the clarifications
