Measurements of trans-ionospheric propagation parameters in the polar cap ionosphere /
Measurements of absolute TEC (Total Electron Content), were made for the first time from the polar cap station located at Thule, Greenland in early 1984 using dual-frequency group delay measurements from high orbit satellites. Measurements of L-band amplitude scintillation and dual-frequency differe...
