Radio waves propagating through small scale plasma density irregularities produce fluctuations in both amplitude and phase of the signal. These fluctuations are called ionospheric scintillations. Due to their spatial diversity, GPS satellites allow scintillation measurement from different azimuthal sectors. Reliability of derived scintillation indices depend on the scintillation estimators used. Here we compare two different estimators for phase scintillations for data obtained from Canadian High Arctic Ionospheric Network (CHAIN) GPS receivers at high latitudes. These stations are specifically chosen to represent polar cap, near to the auroral boundary, and sub-auroral regions . Results of the comparison and its implications will be discussed.
