Comparison of four methods for transionospheric scintillation evaluation

There are a variety of methods employed for determination of phase and amplitude scintillation on satellite signals which generally employ different models and theory. The paper shows that in spite of this, very similar results can be found in most circumstances for four different methods for a very wide range of physical input parameters for weak scintillation conditions. Further comparison between results for different methods can help to determine their modeling errors and hence can also lead to more accurate determinations using improved models.
