Simulation of ESD effects on PCB bus of spacecraft autonomous navigation system

Importance of an investigation of the ESD effects on a printed cictuit board (PCB) bus of spacecraft autonous navigation system is highlighted. Simulation results of the ESD signals propagation along the conductors of the PCB bus are presented. The ESD current source according to the IEC 61000-4-2 was used. The peak voltage of 471 V in the active conductor of the bus with 50 Ohm terminations was obtained. The crosstalk peak voltages in the passive conductors were in the range of 1-32 V.
