Abstract

A satellite communication system that includes a terrestrial base station and a satellite. The satellite communicates with the terrestrial base station using a signal that has a frequency in the range from the S band to visible light. The satellite is configured in a COBRA orbit.

Claims

a terrestrial base station; and

a first satellite communicating with said terrestrial base station using a signal, in the frequency range from the S band to visible light wherein said first satellite is configured in a COBRA orbit.

2. The satellite communication system of claim 1, wherein said communicating includes transmitting said signal between said terrestrial base station and said first satellite;

and

wherein an optimal location for transmitting said signal is determined based on a frequency of said signal and the attenuation of said signal at said frequency.

3. The satellite communication system of claim 2, wherein said attenuation is based on the cloud water content persistent in a region including said optimal location.

4. The satellite communication system of claim 3, wherein said optimal location is defined by longitude and latitude.

5. The satellite communication system of claim 3, wherein said cloud water content is determined based on an exceedance probability.

6. The satellite communication system of claim 3, wherein said cloud water content is determined based on a cloud water content formula.

7. The satellite communication system of claim 3, wherein said optimal location is based on the probability density function of an elevation angle.

8. The satellite communication system of claim 8, wherein said communicating includes receiving said signal between said terrestrial base station and said first satellite;

and

wherein an optimal location for receiving said signal is determined based on a frequency of said signal and the attenuation of said signal at said frequency.

9. The satellite communication system of claim 8, wherein said attenuation is based on the cloud water content persistent in a region including said optimal location.

10. The satellite communication system of claim 9, wherein said optimal location is defined by longitude and latitude.
