Analysis of the heat load imposed upon a satellite by the |
|
energetic particle population trapped in the |
|
magnetosphere indicates that this source of heat can |
|
provide as much as 0.5 W/M-sq for short periods. During |
|
times of magnetic storms, this value can further increase |
|
by half an order of magnitude. This heat source should be |
|
considered for any space system with elements designed to |
|
run below 100 K and becomes nonnegligible for systems |
|
with passively cooled elements (radiators) designed to |
|
run below 75 K. Below 60 K, this may be a major concern |
|
in the design of the thermal system. In general, the |
|
heating due to trapped energetic particles is small in |
|
low altitude orbits, moderate in geosynchronous orbits, |
|
and severe in intermediate orbits such as the GPS orbit. |
|
Average heating in high inclination orbits is lower than |
|
in low inclination orbits. Keywords: Space cryogenics, |
|
Satellite heating, Particle heating. |
