Performance Analysis of Twins4Space: Latency and Data Rates in a
SpaceWire Network
Abstract
Modular space systems are an innovative and future-oriented
concept, offering the flexibility to adapt to diverse mission
requirements. In our previous paper, we introduced the Twins4Space
project, a modular and flexible architecture utilizing a SpaceWire
network to connect distributed nodes. In this paper, we focus on the
empirical performance evaluation of the system, presenting detailed
measurements of its communication layer. Key performance indicators such
as SpaceWire Time-Code latency and network data rates are assessed,
which are essential for maintaining predictable operational conditions
within decentralized nodes. Our findings demonstrate that Twins4Space
can effectively meet the rigorous demands of future space applications,
providing robust communication and swift reconfiguration capabilities.
Furthermore, areas with optimization potential are identified, offering
opportunities for further performance improvements. This validation
underscores the practical potential of the Twins4Space approach in
enhancing the efficiency and reliability of space mission
infrastructure.
