Abstract: The single event latch-ups were frequently recorded in devices onboard a near Earth satellite. The temporal and spacial distributions of the SELs is investigated in this paper by analyzing the variation of the satellite’s orbital elements including the semi major axis, the inclination, the local time of the descending node, and the solar incidence. Details of the space and time characteristics are discussed. For mitigating the SEL effects, an operation method in TT&C (Telemetry, Tracking and Command) is presented by programming a telecontrol schedule run in automation. It is shown that the SEL geographic location has a clear distribution with the proportion of 3:2:1 according to the South Atlantic Anomaly area, the two polar regions, and other places, respectively. The average SEL occurrence rate of the device SEL is above 0.134 d^-1 in the whole orbiting time. For a longer time span, when the sun is active, the rate is lower than 0.103 d^-1 in the solar maximum, and is about 0.165 d^-1 in the solar minimum. In an annual phase, the SEL occurrence rate reaches its peak value of 0.200 d^-1 in December when the Earth goes near the perigee and the sun has a greater influence; this rate drops to 0.072 d^-1 in July when the Earth moves close to the apogee and the sun has a smaller influence. The operation response to SELs in the TT&C relies on the automatic running of a cognitive telecontrol program with an average span of 130 s.
