Many of spacecraft anomalies are caused by discharge on solar array. We investigate two methods to mitigate discharge on the solar array of spacecraft in geostationary orbit (GEO). The first method is to have discharge at safer points before the discharge occurs on solar cells. The second method is not to make the potential of the spacecraft negative. The mitigation prototypes were designed from the...
Recently, an arcing on satellite solar array due to interaction between space plasma and the array threatening safety of spacecraft is a big issue. The arcing causes degradation of solar array at malfunction of instruments on satellites. The discharge is caused by differential potential between satellite body and insulator surfaces like coverglass of solar array, which are charged by ambient plasma...
