Abstract
The MIL-STD-1553B is one of the most used data buses for communication over aircraft and satellites. It requires a large amount of cables to connect all the onboard devices, therefore one of the most challenging issues in Spacecrafts (SCs) design is how to arrange all of them. Moreover, these wired communication systems represent up to 10% of the total mass of the satellite, introducing constraints on the cost of the mission launch and reducing the available room inside the satellite. We present here a novel system that can transport the MIL-STD-1553B signal over optical wireless, effectively removing wired connections. This can save weight and space while maintaining high performance and backward compatibility. We achieved these results by developing an innovative transceiver (TRX) board. The presented Optical Wireless Communication (OWC) system does not suffer from sniffing/jamming or from multipath interference. Moreover, it encompasses only Commercial Off-the-Shelf (COTS) components, so that no special technological development is needed and we can keep its cost low. Here, we first shortly summarize our approach and then discuss how it can be used to deploy OWC links over a SC. To this aim, our system can interface the MIL-STD-1553B data bus with the OWC devices without any modification of the protocol and of the bus architecture.
