Abstract

Modularized design takes great advantage to micro-small satellites. Many modules and subsystems are manufactured individually, needs a distributed on-board data system. A kind of distributed OBDS is carried out, all the modules and subsystems connect to data bus network by ESN. Many kinds of bus can be used in satellite, and CAN, UART and 802.11 represents three typical different kind. The ESN structure is given. Take CAN bus for example, the paper details the process of bus initialization, noting some facts for PnP function.
