“…For that purpose, the CAN protocol was selected since it is one of the most promising fault-tolerant distributed communication protocols being adopted in the micro/nano-satellite community [27]. One of the main advantages of CAN protocol is its maturity level in harsh environments, such as automotive application as discussed in [28]. There are several CAN implementations that can be embraced for space applications.…”

Bus saturation is deemed as one of the primary causes of delays in the data propagation between spacecraft components. However, the conditions under which bus congestion can affect measurements variability were not well characterized before. This work presents a bus saturation model and a set of experiments to characterize the bus performance of satellite missions for different traffic load, data rate, and synchronization periods. The results showed an increase of measurements variance of up to 18% caused by bus saturation. Additionally, an algorithm was proposed to reduce data delay by controlling saturation on the communication channel at operational level.

“…Besides in vehicle application, CAN also has been implemented as a Satellite bus communication [11,12] and Remote Terminal Unit (RTU) in Supervisory Control and Data Acquisition (SCADA) [13]. CAN is a multi-master communication network in which each node has a specific identifier (ID).…”

“…ECC test indicates that data transmission using CAN frames over IP managed to correct the corrupted data up to 10 %. Satellite bus utilizing CAN has limited transmission speed at 1 Mbps [11,12]. But with CAN frame over IP, data transmission can be done via Ethernet with transmission speed up to 10/100 Mbps.…”

“…Current spacecraft systems lend to bespoke and/or proprietary methods of deploying communication networks such as MIL-STD 1553B and Controller Area Network (CAN 2.0) [3]. A full protocol stack could provide the underpinning intercommunications between future spacecraft subsystems while running over a common physical medium that distributes electric power.…”

This is a high-level study into the validation of a unified electric power and communications architecture for modern spacecraft systems. We leverage from blending the European Cooperation for Space Standardisation (ECSS) SpaceWire and the IEEE 802.3 Power over Ethernet (PoE) standards for a common onboard power and communications interface. The focus of the work has been communication performance. The requirements from the protocols of both standards were analysed and combined to create a full protocol stack for SpaceWire PoE. The stack is implemented on an embedded platform represented as a proof-of-concept SpaceWire PoE system. The results of functional testing demonstrate SpaceWire PoE as a valid solution that meets the requirements of both protocols. For the 100 Mb/s links, the SpaceWire PoE throughput is on a par (97.39%) with Ethernet (97.52%) and SpaceWire (99.2%). Shared communication and power architecture is intended for decentralised operation achieving greater autonomy of the integrated subsystems. This potentially may lead to standardisation of electrical, mechanical and communication interfaces across spacecraft subsystem manufacturers, easing harness complexity and routing during the assembly, integration and test (AIT) phase of the spacecraft as well as saving mass and launch cost.
