“…According to these data, in all the links the received optical power value is much higher than the RX sensitivity (−37.5 dBm [26]). As aforementioned, only links between BC and RTs are realized, as the exchange of data between two RTs is always controlled by the BC, in compliance with the standard [23].…”

“…As shown in Fig. 3a, each TRX is composed by three functional parts [26]: the signal adaptation, the TX and the RX. The adaptation module converts the MIL-STD-1553B bipolar differential Manchester-encoded signal into an unipolar single-ended On-Off Keying (OOK) signal, and vice-versa.…”

“…By using a Personal Computer (PC) connected to the TM, we can then extract the relevant information about the status of the connections. In particular, a home-made software routine on the PC reads the logbook of the TMs and converts the various words from the hexadecimal format into a binary format [26]: by analyzing the data streams at bit level, this allows us to monitor the communication performance of all the units on the bus and derive exact information about the status of the OWC-MIL-STD-1553B connections. Before the test of the complete network, we performed a preliminary analysis and assessed the bidirectional commu-nication of the three optical links, individually (i.e., pointto-point link).…”

In a Spacecraft (SC), a huge amount of cabled electrical connections is needed by many different units to exchange digital data. This increases the overall mass, the space occupancy, and the routing design time. Here, we propose and demonstrate an Optical Wireless Communication (OWC) system that can perfectly replace the MIL-STD-1553B cables inside the SC, providing wireless communication among the satellite units, with full backward compatibility with pre-existing units and protocols. We present the experimental demonstration in the challenging environment of a populated mockup of a real SC, where we connect four different units and exploit the Non Line-of-Sight (NLOS) configuration, i.e. take advantage of the scattering from the walls to overcome the shadowing effects. This OWC technique can effectively reduce the overall weight (more than 50%) and cost of the SC data network. The proposed transceivers are based on a transparent, fully analog solution and are made of Commercial Off-the-Shelf (COTS) components, with features compatible with the space environment. The on-field experiment shows that this is a practical solution for the data networks in future SCs.

Given the increasing need of avionics communications and ship electromechanical communications for reliability and real-time transmission, current scheduling schemes waste bandwidth resources. They increase delay because of the low concurrency and the inefficiency of data transmissions in FC-AE-1553 multi-level switching networks. In this study, we first analyze the characteristics of different tasks in the field of avionics communication and establish the FC-AE-1553 network model. We then propose a multi-task hybrid scheduling scheme that includes a static scheduling scheme based on the flow and common divisors of the periods to improve the utilization of bandwidth while ensuring the periodic transmission of deterministic tasks. Further, we exhibit a dynamic bandwidth allocation scheme based on flow and credit ranking to increase throughput and fairness while decreasing the delay of burst tasks. Specifically, to ensure the periodic transmission of deterministic tasks, we divide the transmission time slots according to the common divisor of the period and schedule them in ascending order of period and flow. We update the weights of the credit ranking and flow online, and schedule them in descending order of weight size. The experimental results show that our schemes improve the bandwidth utilization of deterministic tasks by 10% and can balance the throughput and delay of the network. By improving the bandwidth utilization of deterministic tasks, we can provide a better quality of service for burst tasks. When the network can balance its throughput and delay, this shows that the network is efficient and stable.
