This paper aimed to propose diversity method for mitigating tropospheric attenuation in Thailand. Thailand experiences one of the strongest satellite attenuation conditions in the world. Three kinds of data - cloud calculation data, thaicom2&3 satellite beacon data, and rainfall data - indicate how severe tropospheric attenuation is at a moment, calling for some diversity methods to be applied Thailand's attenuation data to increase the efficiency of future satellite communication in Thailand, especially at high Ka band frequency and above.
