Space radiation environment and its effects on satellites: analysis of the first data from TEDA on board ADEOS-II

The Advanced Earth Observing Satellite II (ADEOS-II) was launched into sun-synchronous, sub-recurrent orbit on December 14, 2002, and its operation terminated unexpectedly on October 24, 2003. While in orbit, the Technical Data Acquisition equipment on board ADEOS-II monitored the space radiation environment and its effects, including total-dose and single-event upset, recording them on 16 M and 64 M-DRAM memories. In this paper, we analyze the first data results from these monitors.
