A two-dimensional cross section of the principal ionospheric dip has been reconstructed by satellite radiotomography for the first time. The dip was observed to have a complex structure, with many extrema, on several occasions. A new phase-difference radiotomographic approach is capable of reconstructing global sections of the plasma environment of the earth.
