Abstract:	The objective of this paper is to analyze and compare the spectral characteristics between high latitude and equatorial scintillations based on data from our scintillation monitoring network from Alaska, Hong Kong and Singapore. Ultimately, the results can be used to improve the receiver tracking algorithms at each region independently. The spectrum analysis tool we used in this paper is an adaptive periodogram technique (APT) introduced by our previous studies. We have shown that APT can correctly identify the frequency components in a signal, and it can provide spectrums with high time resolution and frequency resolution. By applying APT, we were able to analyze and compare the selected scintillation data from each monitoring site in the spectral domain. The results show that during large scale phase scintillation events, the high frequency components tend to have larger magnitude and last longer at high latitude regions than at low latitude and equatorial regions.
