[amsat-bb] Effect of Earths Radiation on Satellites

[Clive Wallis <clivew@xxxxxxxxxxxx>]

Hi,

I have been trying to correlate the effect of solar eclipses on the 
internal temperature of OSCAR-11.  Although the temperature does 
follow the average amount of sunshine, there seems to be some other 
effect which is also influencing the temperature.  Perhaps the 
satellite is spending progresively  different amounts of time over 
the hotter or cooler parts of the earth. 

James G3RUH and Graham VK5AGR have  mentioned that the Earth's 
radiation had a noticeable effect on the temperature of OSCAR-13.  I 
just wondered if anyone can suggest any references to the effect of 
the earth's IR radiation on satellites.

I'm looking for a simple way to roughly determine the earth's 
radiation according to position, time and date.   Any help or 
suggestion would be greatly appreciated.
