| Abstract: | To adapt to the development requirements of hierarchical network and using SpaceWire on board, this paper designs a SpaceWire-1553B bridge, it is a remote terminal of 1553B bus, and a controller of SpaceWire network, also implements the bridge between the two bus protocol. Instructions delay time is 16.3us across the buses, and the bridge to refresh all SpaceWire equipment running status information every 0.2S, to satisfy the on-board network instruction response and telemetry update requirements. |
