In this research two years January 2015-December o 2016 tropospheric scintillation records dig out from Astra 2E 2F 2G at E o o Satellite path link observation at Lat N Long E at Ota southwest o Nigeria at GHz and an elevation angle . The result and analysis were likened with some reliable tropospheric scintillation estimate models in order to acquire best model for Ota environment. The result findings revealed that the Karasawa model provides the minimum percentage error for scintillation fades and enhancements of approximately at unavailability of time and at unavailability of time respectively. Hence Karasawa model is the most found suitable for the estimation of transmission loss in this region. Also scintillation intensity is noticed to be high throughout the non-rainy season likened to rainy season months. Conversely the model must be verified more by means of higher frequency band like Ka and V bands to affirm the accurateness of the model. The statistics provided in this work will assistance in fade margin for performance and antenna sizing required for .
